1.4 Parameters

The parameters in the following table are defined in the SCTP section in the SS7 stack configuration file, for example ss7.cnf or sctp.cnf.

Note:: The symbol “Def:” in the column “Values” means that when BASE SCTP is initialized by an old configuration file, which does not support the parameter, this default value is used by SCTP. The default value of the configuration parameter grants backward compatibility behavior.
The symbol “Rec:” in the column “Values” should be treated as a recommended value for the fixed network without lingering disturbances and, therefore, this value doesn't fit all networks, traffic and equipment types, which might be used by customer. The value of the parameters should be set according to the network's quality/capacity/noisiness. It depends on practical experience for the particular case. Parameters recommended for SS7CAF applications see in [E6].

Number Of Associations	Min: 1 Max: 4 096 Since R9D: Max: 8 192 Since R10AE: Max: 16 249 Rec: 512 Def: -	No	The maximum number of associations to be handled by SCTP instance in this configuration. Please note, that each configured association requires certain amount of memory for its handling. It is recommended to limit number of association according to real needs. Refer to [E1] for details.
Interval For Lost User Handling in milliseconds	Min: 0 Max: 3 600 000 Rec: 5 000 Def: 5 000	Yes, applies to all users beginning from the next interval.	Number of milliseconds for the interval, which begins when the connection with SCTP user is lost. During this interval SCTP waits for the reconnection. If it does not happen during this time, the user will be considered as “dead” and all associations related to it will be destroyed. This interval is also applied during broken connection between SCTP instances in case of association movement (Horizontal Takeover and Individual Association Movement). Value 0 means that the user or the other SCTP is considered as “dead” right after the lost connection.
Key Change Period in milliseconds	Min: 1 000 Max: 180 000 Rec: 4 000 Def: -	Yes, applies to SCTP module beginning from the next interval.	Set up how often the secret key used to compute the MAC on the State Cookie is changed.
Number of Local IP Adresses and DNS Hostnames	Min: 0 Max: 512 Rec: 0 Def: 0	Yes, takes affect on newly created endpoints only.	Total number of available addresses and DNS Hostnames. The exact set of addresses, used by SCTP for creation of endpoint, is the intersection of set of addresses provided by SCTP user, set of addresses provided below and a set of addresses provided by operating system. Configuration parameter Multi-home Robustness allows SCTP to create endpoints for IP addresses which are listed below but not provided by SCTP user and/or operating system. Value 0 means that any IPv4 and IPv6 addresses that are provided by SCTP user and operating system can be used. Note: the maximum number of local IPv4 addresses and the maximum number of local IPv6 addresses that can be supported by SCTP are limited by 255. The configuration that includes more than 255 IPv4 or IPv6 addresses will be passed but only 255 IPv4 or IPv6 addresses of them will be used as available.
Local IP address or DNS Hostname in Internet Standard format	Min: - Max: - Rec: — Def: All local IP addresses available	Yes, takes affect on newly created endpoints only. Note: IP addresses can not be removed from the registered endpoints. Already established endpoints and associations continue to use IP addresses, which even removed from this list. If IP addresses are removed from the system also, SCTP associations will detect changes in the status of network.	Local IP address available. The format of the IP address should be of Internet Standard format: "a.b.c.d", example 150.168.200.18 for IPv4 addresses or "a:b:c:d:e:f:g:h", example 2031:0:130F:0:0:9C:8A:130F for IPv6 addresses Note: IPv6 addresses in the compressed format are allowed, example: 2031:0:130F::9C:8A:130F. Local DNS available. Text string composed of the alphabet (A-Z), digits (0-9), minus sign (-), and period (.). No blank or space characters are permitted as a part of the name. The first character must be an alpha or digit character. The last character must not be a minus sign. DNS Hostname must not be in #.#.#.# dotted-decimal form.
The field Local IP address or DNS Hostname is repeated Number of Local IP Adresses and DNS Hostnames times.
Size of Outgoing IP Buffer in number of bytes	Min: 1 500 (including IP header size, that is 20 bytes in the IPv4 case and 40 bytes in the IPv6 case) Min: 1 300 (including IP header size, that is 20 bytes in the IPv4 case and 40 bytes in the IPv6 case) Max: 65 535 (including IP header size, that is 20 bytes in the IPv4 case and 40 bytes in the IPv6 case) Rec: max(“ Maximum IPv4 PMTU” + 20, “ Maximum IPv6 PMTU” + 40) Def: -	Yes, applies to SCTP module and to all sockets as their option. This parameter can not be reduced. If default system or previous value is greater than provided, this parameter is not applied to sockets but new configuration is accepted.	Sets the maximum number of bytes which SCTP can write to IP socket. Parameter is validated for compliance to possible range. If it is smaller initially than default system value (usually 8 192 bytes), it is not applied but configuration is accepted. If outgoing SCTP packet is greater than size of this buffer this packet will be lost. So, it is strongly recommended to synchronize this value with PMTU.
Size of Incoming IP Buffer in number of bytes	Min: 0 Max: 5 000 000. Rec: 0 Def: —	Yes, applies to all sockets as their option. This parameter can not be reduced. If default system or previous value is greater than provided, this parameter is not applied to sockets but new configuration is accepted.	Sets the maximum number of bytes which is used by IP layer when receive packets from the network. If 0 is specified, the operating systems default value is used. The maximum value is operating system specific. Parameter is validated for compliance to possible range (usually 8 192). If it is smaller initially (but not zero) than the default system value, it is not applied but the configuration is accepted. Note: In case of using Distributed Endpoint between SCTP FEs on the same host functionality based on TUN interfaces, it is responsibility of operator to set the value of this parameter to greater than 0 and align it with the real IP layer properties. Otherwise the configuration will be accepted, but incomplete packets may be received, which SCTP will discard due to incorrect checksum. See chapter "Distributed Endpoint between SCTP FEs on the Same Host" in [E1] and [E3] for details. If incoming packet is greater than this parameter, IP layer will provide incomplete packet and SCTP will discard it due to incorrect checksum. But if IP layer provides complete packet and checksum is correct SCTP will forward this packet to the SCTP user even though the length of the packet is greater.
CRC-Calculation Status	Min: 0 Max: 1 Rec: 1 Def: 1	Yes, applies to SCTP module.	Defines whether CRC calculation is active or not. 0 - CRC is not active; SCTP delegates CRC calculation to lower layers 1 - CRC calculation is active; SCTP calculates the CRC. It is strongly not recommended to set this parameter to 0 on Solaris 10 platform, because this can prevent any traffic to run.
ICMP Status	Min: 0 Max: 1 Since R10P: Max: 7 Rec: 1 Def: 1	No Since R10P: Yes	Determines if SCTP handles ICMP messages or not. Bit 0 (activation): 0 - ICMP status is set to inactive; SCTP will have no possibility to handle ICMP messages. 1 - ICMP status is set to active; SCTP will open a socket and receive ICMP messages. Bit 1 (ignoring ICMP with code “protocol unreachable”): 0 – ICMP packets with code “protocol unreachable” are not ignored by SCTP and handled according to E2. 1 – ICMP packets with code “protocol unreachable” are ignored by SCTP. Bit 2 (ignoring ICMP with type “destination unreachable”): 0 – ICMP packets with type “destination unreachable” are not ignored by SCTP. 1 – ICMP packets with type “destination unreachable” (except ICMP with codes “protocol unreachable” and “fragmentation needed”) are ignored by SCTP. Note: Bit 1 (ignoring ICMP with code “protocol unreachable”) and Bit 2 (ignoring ICMP with type “destination unreachable”) do not have any effect if Bit 0 (activation) equals to zero. It is recommended to set ICMP Status parameter to 1 if PMTUD was enabled.
Bind To Device Flag	Min: 0 Max: 1 Rec: 0 Def: 0	Yes, takes affect on newly created sockets only.	Activate/deactivate Bind To Device or not. For platforms that do not support the socket option, the parameter has no effect. 0 - SCTP does not try to force the socket option BINDTODEVICE to be set when opening sockets 1 - SCTP tries to force the socket option BINDTODEVICE to be set when opening sockets
ULM Buffer Size in number of bytes	Min: 0 Max: 10 000 000 Rec: 500 000 Def: 0	No Since R10X: Yes, if Total Assured Memory parameter is set to 0. Otherwise, no.	Defines limitation for buffer that is assigned for upper layer messages. SCTP will not save confirmations and indications if the buffer is overflowed. Zero means that buffer is unlimited, hence the memory can be exhausted by SCTP. Note: In case if it is reconfigured, and new limit is lower than actual amount of buffered data, no actions will be done. It means that buffer will not be cleaned. But it will be decrease eventually. Note: See also ULM SFI part and ULM Info Ind Part.
Total Assured Memory in number of bytes	Min: 0 Max: max size, that operating system can provide Rec: Depends on other configuration parameters and system properties. For details see chapter “Memory handling” in [E1]. Def: 0	No	Defines limitation for memory usage. Zero means that memory is unlimited, then SCTP will use expandable CP pools. If parameter is not equal to zero SCTP will allocate dynamic memory during MM_INIT_req processing and will not use more than configured. It is strongly recommended to set up the parameter if operating system can not return NULL pointer for allocation request in case of low memory. Parameter may be set to zero if operating system has swap for operative memory. For more details see chapter “Memory handling” in [E1].
ULM SFI Part in percents	Min: 0 Max: 100 Rec: 70 Def: 70	No Since R10AF: Yes	Identifies the part (in percents) of ULM buffer (ULM Buffer Size), which may be filled with SCTP_SEND_FAILURE_ind messages. If this parameter is equal to zero SCTP_SEND_FAILURE_ind will not be buffered. See [E1] (chapters 2 and 5) for more details. Note: in case of reconfiguration if the new value is less than the currently used space in ULM buffer allocated for primitives, SCTP will apply the new value but the new limit will take a role only when enough buffered primitives are released. Note: in case of reconfiguration if a new value is greater than the old one, SCTP will simply apply the new value. But if there is not enough space in ULM buffer due to buffered primitives of another type, SCTP will be able to buffer new SCTP_SEND_FAILURE_ind primitives only when enough buffered primitives are released.
Port Range From	Min: 0 Max: “ Port Range To” Rec:- Def: -	No	Smallest port which can be dynamically assigned by SCTP to endpoint. Port range from value must be more than zero to assign port dynamically from range. If ” Port Range From” is equal to zero and ” Port Range To” is equal to zero, SCTP uses FE-instance number to assign port, see primitive SCTP_INITIALIZE_req in [E1] for more information. Note, that if ” Port Range From” is equal to zero, then ” Port Range To” must be equal to zero too, otherwise SCTP will return an error.
Port Range To	Min: 0, higher or equal to “ Port Range From” Max: 65 535 Rec:- Def: -	No	Greatest port which can be dynamically assigned by SCTP to endpoint. If ” Port Range From” is equal to zero and ” Port Range To” is equal to zero, SCTP uses FE-instance number to assigned port, see primitive SCTP_INITIALIZE_req in [E1] for more information. If ” Port Range To” is equal to zero, then ” Port Range From” must be equal to zero too, otherwise SCTP will return an error.
Reconfiguration settings Available since R9	Min: 0 Max: 2 Rec: 2 Def: 2	Yes, applies to SCTP module. New value of this parameter is applied to next reconfiguration session.	This parameter is used during module reconfiguration. Value of Reconfiguration settings parameter shows how reconfiguration will be applied to associations. 0 - reconfigured parameters will be applied only to new associations started from existing or newly created endpoints. 1 - reconfigured parameters will be applied to existing and new associations, except Initial RWND, which, if decreased, will be applied only to new associations (association opened after the reconfiguration on the existing or new endpoints). 2 - the same as 1. Note: In case of configuration when upgrading or when it is necessary to restart the SCTP Front End process the Reconfiguration settings parameter value is ignored and configuration parameters will be applied only to new associations established afterwards. Note: SCTP configuration is not applied to an association after the movement from another SCTP Front End in the scope of Horizontal Takeover and Individual Association Movement (Horizontal Takeover can be used for SCTP Front End upgrade scenarios and can follow SCTP Front End process restart).
PMTUD Accuracy in number of bytes Available since R9	Min: 0 Max: 32 000 Rec: 12 Def: 0 Must be divisible by 4 bytes	Yes, applies to running PMTUD process immediately	Defines the precision for PMTU discovery process. If range to find PMTU is less than PMTU Accuracy then PMTUD is complete for path. If PMTUD Accuracy is equal to zero PMTUD is disabled. If PMTUD Accuracy is not equal to zero and needed for Path MTU Discovery socket options are not supported by IP layer (see E1), such configuration will not be applied. If PMTUD Accuracy is not equal to zero and Size of outgoing IP buffer is less than max(Maximum IPv4 PMTU + 20, Maximum IPv6 PMTU + 40), such configuration will not be applied. It is recommended to set ICMP Status parameter to 1 if PMTUD was enabled. Note: In case of using Distributed Endpoint between SCTP FEs on the same host functionality based on TUN interfaces, Path MTU Discovery will work correctly for IPv6 only if the value of Maximum IPv6 PMTU is set less than the currently configured PMTU of Operating System. Path MTU Discovery will work correctly for IPv4 only if the platform routing component drops IPv4 packets with the size greater than real MTU. See chapter "Distributed Endpoint between SCTP FEs on the Same Host" in [E1] and [E3] for details.
PMTUD Interval in milliseconds Available since R9	Min: 300 000 Max: 2³²-1 Rec: 7 200 000 Def: 7 200 000	Yes, applies to SCTP module starting from next interval.	Describes time interval between PMTUD processes. Parameter is for the whole module. Maximum one association path is being discovered at any moment of time. (Parameter makes sense only if PMTUD Accuracy is nonzero)
Wait Next Probe interval in milliseconds Available since R10	Min: 0 Max: 3 600 000 Rec: 120 000 Def: 120 000	Yes, applies to SCTP module	Describes time interval to wait after a successful PMTUD probe before sending the next probe on that path. After an unsuccessful probe PMTUD procedure will wait for five times this value before sending a new probe. (Parameter makes sense only if PMTUD Accuracy is nonzero)
Number of Attempts to Discover Congested Paths Available since R10	Min: 0 Max: 255 Rec: 0 Def: 0	Yes, applies to running PMTUD process immediately	Describes Number of Attempts to Discover Congested Paths. If the number of attempts spent to discover a congested path is equal to this parameter SCTP will mark the path as discovered. If the value is equal to zero SCTP will try to discover congested paths till the congestion is ceased or the path is inactivated. (Parameter makes sense only if PMTUD Accuracy is nonzero)
Minimum IPv4 PMTU in number of bytes Available since R9	Min: 68 Max: Maximum IPv4 PMTU Rec: 508 Def: 508	New value of the parameter will be applied to all associations.	Describes lower value to find PMTU on IPv4 paths. Used to reset path MTU if Datagram Too Big ICMP message received and Next-Hop MTU field not set in this message.
Maximum IPv4 PMTU in number of bytes Available since R9	Min: Minimum IPv4 PMTU Max: Size of outgoing IP buffer - 20 Rec: 65 515 Def: 65 515	New value of the parameter will be applied to all associations.	Describes upper value to find PMTU on IPv4 paths. SCTP will not send probes with size more than Maximum IPv4 PMTU. It is strongly recommended to set the value of this parameter to Size of outgoing IP buffer minus the size of IP header. 20 bytes is the minimum value of the size of IP header which is used to validate this parameter. It is recommended to set the value of this parameter to not greater than the currently configured pmtu of Operating System. Otherwise SCTP will report SCTP_ERROR_WRITE_SOCKET each time after sending of a probe packet with the size greater than that pmtu. Nevertheless Path MTU Discovery will be continued.
Maximum IPv6 PMTU in number of bytes Available since R9	Min: 1 240 Max: If PMTUD Accuracy activates PMTU discovery process - equal to Size of outgoing IP buffer - 40. Otherwise - equal to 65 495. Rec: 65 495 Def: 65 495	New value of the parameter will be applied to all associations.	Describes upper value to find PMTU on IPv6 paths (it makes sense only if PMTUD Accuracy is nonzero). SCTP will not send probes with size greater than Maximum IPv6 PMTU. It is strongly recommended to set the value of this parameter to Size of outgoing IP buffer minus the size of IP header. 40 bytes is the minimum value of the size of IP header which is used to validate this parameter. It is recommended to set the value of this parameter to not greater than the currently configured pmtu of Operating System. Otherwise SCTP will report SCTP_ERROR_WRITE_SOCKET each time after sending of a probe packet with the size greater than that pmtu. Nevertheless Path MTU Discovery will be continued. Note: In case of using Distributed Endpoint between SCTP FEs on the same host functionality based on TUN interfaces, Path MTU Discovery will not work correctly if the value of this parameter is set greater than the currently configured PMTU of Operating System. See chapter "Distributed Endpoint between SCTP FEs on the Same Host" in [E1] and [E3] for details.
Start Delay in milliseconds Available since R9	Min: 0 Max: 2³²-1 Rec: 1 000 Def: 0	Yes	Normally SCTP does not keep a connection with other SCTP layer. However, SCTP module communicates with other instances in order to check ' FE ID' parameter. The option ' Start Delay' configures the behavior. The verification procedure is performed with help of SCTP_INFO_req(s) which are distributed to all running SCTP FE(s). If timer is expired earlier than all SCTP_INFO_conf(s) are received, SCTP checks only available answers. Delayed responds from other SCTP instances are ignored. Notice that SCTP can not be used by ULP while this timer is running, since the module is not 'started' at that moment. For more details see chapter “Automatic verification of Configuration->general(FEID)” in [E1].
Takeover Process Limit in milliseconds Available since R9	Min: 10 000 Max: 2³²-1 Rec: 30 000 Def: 30 000	Yes, applies to SCTP module	Limit for the horizontal SCTP take over process. SCTP starts timer when process is started and reports alarm to Management Module when this timer is expired.
Unloading Maximum Number of Associations Available since R9A	Min: 0 Max: 4 096 Rec: 1 Def: 4 096	Yes, applies to SCTP module	Limits the number of associations which start unloading procedure at the same moment.
Unloading General Delay in milliseconds Available since R9A	Min: 0 Max: “ Interval For Lost User Handling” Rec: 200 Def: “ Interval For Lost User Handling”	Yes, applies to SCTP module	For SCTP which takes over associations: defines the time while SCTP waits binding with redirected users. For SCTP which is going to be unloaded: defines the delay before the first burst of unloaded associations.
Unloading Burst Delay in milliseconds Available since R9A	Min: 10 Max: 100 000 Rec: 100 Def: 1 000	Yes, applies to SCTP module	Defines the interval between two bursts of associations which start unloading procedure during association movement procedure.
Would Block ceased Trigger in percents Available since R9B	Min: 0 Max: 99 Rec: 70 Def: 0	Yes	The option is provided to CP module as a threshold of triggered event: WB ceased. If default value is used callback is not registered in CP. This parameter is linked with the functionality in CP module and may depend on platform specific. See [E3] chapter 5.3.29.
FE ID Available since R9	Min: 0 Max: 256 Rec: 256 Def: CP InstanceID	No	Parameter is unique identifier for SCTP FE process. Configuration should guarantee that the value of this parameter is unique for each SCTP module in a system. If it is equal to 256, CP process instance will be assigned instead. For more information about this parameter see [E1] (chapter 2). Note: Value of this parameter should be equal to Instance Id. See [E1] (chapter 4.16).
Associations release burst timer in milliseconds Available since R10C	Min: 0 Max: 65535 Rec: 100 Def: 0	Yes	Defines the time interval between the burst of association releases. If set to 0, SCTP will just return the execution control after each burst. The parameter is ignored if Associations release burst size is set to 0.
Associations release burst size Available since R10C	Min: 0 Max: 8192 Since R10AE: Max: 16 249 Rec: 512 Def: 0	Yes	Defines the maximum number of SCTP associations that can be released without returning the execution control. After this number of associations is released, the Associations release burst timer will be started and release of associations will be continued after its expiration If set to 0, all associations will be released at once and parameter Associations release burst timer will be ignored. Note: The value of this parameters should not be greater than CP configuration parameter MSGMAXENTRIES. Note: Since configuration version R10AF, if Management behaviour bitmask bit 0 is set to 0 and Associations release burst size has non-zero value, SCTP configuration will be rejected.
Individual Takeover Process Time Limit in milliseconds Available since R10E	Min: 0 Max: 2³²-1 Rec: 10 000 Def: 10 000	Yes, applies to SCTP module	Limit for the Individual Association Movement process. If the timer was expired before the successful association movement, SCTP reports unsuccessful result and cleans all information regarding the association.
SCTP over UDP Available since R10F	Min: 0 Max: 1 Since R10AB: Max: 2 Rec: 0 Def: 0	No	SCTP bearer type. Can be UDP or IP. UDP is not recommended to be used in production. UDP may be used for testing on hosts without root access. Values: 0 - IP bearer 1 - UDP bearer, local and remote UDP ports are taken from: UDP Local Port and UDP Remote Port accordingly. 2 - UDP bearer, local and remote UDP ports are taken from endpoint and association SCTP objects. Note: in order to establish the association over UDP, both (remote and local) SCTP endpoints should be configured with UDP bearer.
UDP Local Port Available since R10F	Min: 0 Max: 65535 Rec: - Def: 0	No	UPD local port number if UDP bearer is used.
UDP Remote Port Available since R10F	Min: 0 Max: 65535 Rec: - Def: 0	No	UPD remote port number if UDP bearer is used.
Statistics 64bit Update Timer in milliseconds Available since R10G	Min: 0 Max: 2³²-1 Rec: - Def: 0	Yes	Defines the time interval between comparison of SCTP_STATISTIC_ID_REC_BYTES_LO and SCTP_STATISTIC_ID_SENT_BYTES_LO statistics with their previous values. If the previous value is greater than the current one, the appropriate statistic counter (SCTP_STATISTIC_ID_REC_BYTES_HI or SCTP_STATISTIC_ID_SENT_BYTES_HI) is increased by one, then the timer is restarted. If it is set to zero, corresponding timer is not started and statistic counters SCTP_STATISTIC_ID_REC_BYTES_HI and SCTP_STATISTIC_ID_SENT_BYTES_HI are not updated. It is recommended to set the parameter to non-zero value only if 64bit counters are needed. In this particular case the value of the timer may be calculated with the formula below: [Statistics 64bit Update Timer] 2³⁵ * 10³ / (X * N) Where X is speed in bits per second, N is a number of available for SCTP IP addresses.
DNS Host Name Resolving Interval in milliseconds Available since R10H	Min: 0 Max: 2³²-1 Rec: 86 400 000 Def: 0	Yes, applies to SCTP module starting from next interval.	The timer is used to periodically resolve all configured DNS host name addresses. The value 0 means that the timer is not started at all and if at least one DNS host name address was unresolved, the configuration is rejected. It is not recommended to configure the new timer to a low value (at least not less than 30 seconds) to reduce the load on the DNS server.
Interval For Lost Primitives Check in milliseconds Available since R10I	Min: 0 Max: 2³²-1 Rec: 5 000 Def: 0	Yes, applies to SCTP module. Note: Reconfiguration will take effect with the next timer start.	Defines the time interval since SCTP_OVERLOAD_CONGESTION_LEVEL_req or SCTP_USER_CONGESTION_LEVEL_req primitive is received after which SCTP will check with the upper layer whether corresponding congestion abatement has ceased. If the timer is configured with zero value, SCTP will not start this timer and will never check for lost primitive.
Multi-home Robustness Available since R10K	Min: 0 Max: 1 Rec: 1 Def: 0	Yes, applies to SCTP module.	Defines if SCTP should allow the user to initialize an endpoint if some of local IP addresses are absent in the system: 0 - SCTP does not initialize an endpoint if some of its local IP addresses are absent in the system; 1 - SCTP initializes an endpoint if some of its local IP addresses are absent in the system. Note: even if this parameter is configured to 1, SCTP will not initialize an endpoint if all its local IP addresses are absent in the system.
Exhaustive IP Path Statistic Calculation Available since R10L	Min: 0 Max: 1 Rec: 0 Def: 0	Yes, applies to SCTP module.	Defines whether IP path statistic "Number of control chunks received by SCTP" and "Number of received by SCTP bytes" calculation is active or not: 0 - Statistic calculation is not active, counters "Number of control chunks received by SCTP" and "Number of received by SCTP bytes" will be always equal to zero for IP paths; 1 - Statistic calculation is active, counters "Number of control chunks received by SCTP" and "Number of received by SCTP bytes" will be counted for IP paths. It is recommended to set this parameter to 0, otherwise performance penalty will be observed. Note: even if "Exhaustive IP path statistic calculation" equals to 0, counters "Number of control chunks received by SCTP" and "Number of received by SCTP bytes" still will be calculated per SCTP association and per module.
Initial RWND Setting Timeout in milliseconds Available since R10N	Min: 0 Max: 2³²-1 Rec: 0 Def: 0	Yes, applies to only newly established associations.	This timer is used by SCTP if association establishment is initiated by the remote peer and there is no matched Remote Endpoint Block. If the value is not equal to 0, SCTP uses Initial CWND defined depending on Maximum Initial CWND as Initial RWND value during association establishment and starts the Initial RWND Setting timer right after COOKIE_ACK sending. If the timer is expired SCTP sets new RWND as the current RWND + (Initial RWND from the assigned Configuration Group - Initial RWND of the association). If the SCTP user updates Configuration Group of the established association during the Initial RWND Setting Timeout SCTP stops the timer and sets new RWND as the current RWND + (Initial RWND from the provided Configuration Group - Initial RWND of the association). If the configured RWND is less than value used during association establishment then SCTP will not change RWND of the established association in order to avoid RWND shrinking. If the value is 0, SCTP will use the configured Initial RWND from assigned Configuration Group.
Maximum Number of Endpoint Users Available since R10Q	Min: 1 Max: 65535 Rec: - Def: 64	No	Defines the maximum number of endpoint users. It is recommended to configure the value as low as possible dependently on the system configuration in order to allow SCTP to allocate less memory.
Management behaviour bitmask Available since R10V	Min: 0 Max: 1 Rec: 1 Def: 0	Bit 0: yes, applies at next module termination. The behaviour does not depend on Reconfiguration Settings value.	Bitmask defining management behaviour of SCTP. Bit 0 (Should MM_ORDER_conf[TERMINATE] be delayed until all objects are destroyed.): 0 – MM_ORDER_conf[TERMINATE] is sent immediately after MM_ORDER_req[TERMINATE]. 1 – MM_ORDER_conf[TERMINATE] is sent as soon as all internal objects are deallocated and destroyed (associations are released). In case if bit 0 of Management behaviour bitmask is set to 1, following recommendations for timers should be considered: – (Associations release burst timer * Number of associations / Associations release burst size) < TSTOP timer (configured in oam.cnf, see E5). – (Associations release burst timer * Number of associations / Associations release burst size) < Transaction timer * Number of modules inside FE process (configured in mm.cnf). Note: If mm.cnf (see E4) is not used, then Transaction timer value is 600000 milliseconds. These recommendations are needed in order to avoid expiration of TSTOP timer at OAM and Transaction timer at MM, thus to avoid unexpected errors reported by management application. Bits 1-7: reserved for future and should be set to 0. Note: Since configuration version R10AF, if Management behaviour bitmask bit 0 is set to 0 and Associations release burst size has non-zero value, SCTP configuration will be rejected.
Check IP Interfaces Timer Value in milliseconds Available since R10AA	Min: 0 Max: 2³²-1 Rec: 60000 Def: 60000	Yes, applies to SCTP module. Note: Reconfiguration will take effect with the next timer start. If value is reconfigured to 0, then already running timer will be stopped.	This timer is used by SCTP to monitor statuses of network interfaces when Multi-home Robustness is enabled. At the timer expiration, SCTP will check if some IP interfaces become available or unavailable. The timer will be restarted. The timer is only used on the platforms where CP notifications on IP events are not supported (for details see [E3]). On other platforms the timer will never be started even if it is configured with nonzero duration. If timer is set to 0, then it will never be started.
CRC32C Algorithm Available since R10AG	Min: 0 Max: 2 Rec: 2 - if CRC32 HW instruction is available; 1- if CRC32 HW instruction is unavailable Def: 0	Yes, applies to SCTP module.	Defines which CRC32C calculation algorithm will be used: 0 – Slicing-by-4 algorithm; 1 – Slicing-by-8 algorithm; 2 – Using CRC32 HW instruction. If value 2 is configured but CRC32 HW instruction is not available (for information what CRC32 instruction CPU supports and for the detailed description of the algorithms see [E3]), the configuration is not rejected and SCTP switches to Slicing-by-8 calculation algorithm. Note: This parameter is ignored if CRC-Calculation-Status is 0.
Maximum User Message Size in bytes Available since R10AH	Min: 1 Max: 2³² - 1 Rec: - Def: 65 000	Yes, if Total Assured Memory is set to 0. Then applies to SCTP module. Otherwise, no.	Defines the maximum user message size that can be received by SCTP. When the value is greater than 65 000 bytes, SCTP allocates one additional memory block to buffer and reassemble the message before sending to the network. Note: The parameter value less than 65 000 is ignored. The default value is used instead. Note: The maximum possible value is limited by the system (maximum memory pool block size supported by Common Parts) and cannot be more than (2³² - 1) bytes. For more information see [E3].
ULM Info Ind Part in percents Available since R10AK	Min: 0 Max: 100 Rec: 0 Def: 0	Yes	Identifies the part (in percents) of ULM buffer (ULM Buffer size), which may be filled with SCTP_INFO_ind primitives. If this parameter is equal to zero SCTP_INFO_ind primitives can fill all free space of ULM buffer. If this parameter is none-zero SCTP_INFO_ind primitives will not occupy space of ULM buffer over the set value. See [E1]. Note: In case of reconfiguration if the new value is less than the currently used space in ULM buffer allocated for SCTP_INFO_ind primitives, SCTP will apply the new value but the new limit will take a role only when enough buffered primitives are released. Note: In case of reconfiguration if a new value is greater than the old one, SCTP will simply apply the new value. But if there is not enough space in ULM buffer due to buffered primitives of another type, SCTP will be able to buffer new SCTP_INFO_ind primitives only when enough buffered primitives are released.
Number Of Optional Configuration Groups Available since R9	Min: 0 Max: 16 Since R10N: Max: 254 Rec: - Def: 0	Yes, possible to add or remove new groups.	Defines number of configuration groups which are presented in the configuration file. Possible values: Zero value of this parameter means that it will be only one general configuration group in configuration file. All configuration groups are disposed after the parameter “ Number Of Optional Configuration Groups”, and repeated N + 1 times, where N is equal to parameter “ Number Of Optional Configuration Groups”. All configuration groups follow one after another without any dividers.
Configurations groups Configuration Group parameters must be repeated (Number Of Optional Configuration Groups + 1) times.
Configuration Group ID Available since R9	Min: 0 Max: 16 Since R10N: Max: 254 Rec: - Def: -	Yes, possible to add or remove new groups.	The ID of the SCTP Configuration Group, which combines all protocol parameters which are used to initialize Endpoints and Associations objects. The order of configuration groups is free. Each configuration group should have unique Configuration Group ID. General Configuration Group (“ Configuration Group ID” = 0) must present in the configuration file. If only General Configuration Group is present in configuration file (“ Number Of Optional Configuration Groups” = 0), then “ Configuration Group ID” shall be set to zero value. Note: It is possible to remove Configuration Group during reconfiguration. If some SCTP objects still refer to this Configuration Group, they will be reconfigured by SCTP by using the following way: If an endpoint is using Configuration Group which is going to be removed, the endpoint will be automatically reconfigured to use the General Configuration group (“ Configuration Group ID” = 0). If an association is using a configuration group which is going to be removed, the association will be automatically reconfigured to use configuration group of its endpoint. Update of an affected object (endpoint or association) with the properties of its new configuration group depends on whether the object is attached to or attached from its configuration group. For more information see the chapter "Attachment and Detachment of Configuration Group to Associations and Endpoints" in [E1].
Minimum RTO in milliseconds	Min: 10 Max: 5 000 Rec: 200 Def: -	The behavior depends on Reconfiguration Settings value.	The minimum value that RTO is allowed to take. If when computing the RTO the result is less than the minimum, RTO is rounded up to value of this parameter. According to the [E2], this parameter is recommended to be equal to 1 000 milliseconds.
Maximum RTO in milliseconds	Min: larger than “ Minimum RTO” Max: 120 000 Rec: 800 Def: -	The behavior depends on Reconfiguration Settings value.	The maximum value that RTO is allowed to take. If when computing RTO the result is greater than the maximum, RTO shall be rounded down to Maximum RTO. According to the [E2], this parameter is recommended to be equal to 60 000 ms.
Initial Retransmission Time-Out (RTO) in milliseconds	Min: “ Minimum RTO” Max: “ Maximum RTO” Rec: 400 Def: -	Yes, will be applied only to newly established associations.	This is the initial value that the RTO will take, prior to the first RTT measure. According to the [E2], this parameter is recommended to be equal to 3 000 ms.
RTO Alpha Index	Min: 1 Max: 4 Rec: 3 Def: -	The behavior depends on Reconfiguration Settings value.	This parameter is used to compute the value of the SRTT for a particular destination address. It is used to weight up the RTT measures and its value must be between 0 and 1 (0 < RTO.Alpha < 1). A value close to 1 gives more importance to the last RTT measure. The range of possible values in the configuration file, and the actual value given to the parameter within the module, are the following: . value = 1 -> RTO.alpha = 1/2 . value = 2 -> RTO.alpha = 1/4 . value = 3 -> RTO.alpha = 1/8 . value = 4 -> RTO.alpha = 1/16 According to the [E2], RTO.Alpha is recommended to be 1/8.
RTO Beta Index	Min: 1 Max: 4 Rec: 2 Def: -	The behavior depends on Reconfiguration Settings value.	This parameter is used to compute the value of the RTTVar of a destination address. Similarly to RTO.Alpha, it is used to weight up some of the terms within the equation used to compute the RTTVAR: RTTVAR = (1 - RTO.Beta)RTTVar + RTO.Beta\|SRTT - lastRTT\| Its value must be between 0 and 1 (0 < RTO.Beta < 1). A value close to 1 gives more importance to the last observed variation. The range of possible values in the configuration file, and the actual value given to the parameter within the module, are the following: . value = 1 -> RTO.beta = 1/2 . value = 2 -> RTO.beta = 1/4 . value = 3 -> RTO.beta = 1/8 . value = 4 -> RTO.beta = 1/16 According to the [E2], RTO.Beta is recommended to be 1/4.
Valid Cookie Life in milliseconds	Min: 1 000 Max: 180 000 Rec: 60 000 Def: -	Yes, will be applied only to newly established associations.	This parameter sets up the lifespan of the State Cookie sent in the INIT_ACK chunk. It is used to limit the valid amount of time between the sending of the INIT_ACK chunk and the reception of a COOKIE_ECHO chunk when establishing an association. If a COOKIE_ECHO chunk arrives after Valid Cookie Life delay since the INIT_ACK was sent, it is discarded and, therefore, no association is established According to the [E2], this parameter is recommended to be equal to 60 000 ms.
Allowed Increment Cookie Life in milliseconds	Min: 0 Max: 180 000 Rec: 0 Def: -	Yes, will be applied only to newly established associations.	The sender of an INIT chunk may request the remote endpoint to increase a cookie life-span (for instance, if a previous attempt to connect failed due to a stale-cookie error). If the value sent in the "Cookie Preservative" field of the INIT chunk is less than or equal to this parameter, the receiver of the INIT will increase the valid cookie life in the number of milliseconds specified. If the value present in the "Cookie Preservative" is greater than this parameter, the cookie life shall be incremented in the number of milliseconds specified by the parameter. Some considerations about this parameter: for security reasons the server may want to ignore any increase on the cookie life-span (increasing the value of the cookie life-span means more time for an attacker to break our key), so the value of this parameter would be set to zero. The “Maximum Cookie Life”, that is the “ Valid Cookie Life” plus the “ Allowed Increment Cookie Life”,
Assoc.Max.Rtx in number of attempts	Min: “ Path.Max.Rtx” Max: 20 Rec: if “ Path Selection Adjustment” activates scheme B (“PATH”) - equal to Path.Max.Rtx * (number of IP paths) if “ Path Selection Adjustment”” activates scheme A (“PEER”) - equal to Path.Max.Rtx * (number of SCTP paths) Def: -	The behavior depends on Reconfiguration Settings value. Active associations which have association error counter greater than newly provided align counter with new Assoc.Max.Rtx value. Thus, if the next sent packet is lost the association will be closed.	This is the maximum number of consecutive unsuccessful retransmissions to a remote peer (on all the destination transport addresses of the peer if it is multihomed). If the number of retransmissions becomes greater than this value, the remote peer is considered as unreachable and the association is closed down. The value of this parameter should be greater than or equal to “ Path.Max.Rtx” . For a specific association, it may happen that all the IP paths become inactive without overpassing the “ Assoc.Max.Rtx”. In this case, BASE SCTP behavior depends on the path selection scheme (see Path Selection Adjustment) used for the association: If the scheme A ("PEER") is used, the association will be closed. If the scheme B ("PATH") is used, the association will be moved to the dormant state and will not be closed. For more information on the dormant state of association see [E1]. According to the [E2], this parameter is recommended to be equal to 10.
Path.Max.Rtx in number of attempts	Min: 1 Max: “ Assoc.Max.Rtx” Rec: for single homed association - 2 for multihomed association: if Path Selection Adjustment activates scheme B (“PATH”) - 1 if Path Selection Adjustment activates scheme A (“PEER”) - “ Number of Local IP Addresses and DNS Hostnames” which are available for an SCTP endpoint. Def: -	The behavior depends on Reconfiguration Settings value. Active associations which have path error counter greater than newly provided align counter with new Path.Max.Rtx value. Thus, if the next sent packet is lost the path will be considered as unreachable.	Maximum number of consecutive retransmissions via specific IP path (local IP address - remote IP address pair). If the number of retransmissions becomes greater than this value, the IP path is considered "inactive" (see [E1] for how SCTP handles "inactive" IP paths). If Path Select Adjustment activates scheme A (“PEER”) [E1] this parameter is extrapolated to destination transport addresses. And it defines maximum number of consecutive retransmissions to remote address. If all IP paths linked with one remote address are "inactive" remote address is also considered as "inactive". According to the [E2], this parameter is recommended to be equal to 5.
Maximum Initial Retransmissions in number of attempts	Min: 1 Max: 16 Rec: 8 Def: -	The behavior depends on Reconfiguration Settings value.	The maximum number of retransmissions allowed for both INIT and COOKIE-ECHO chunks. If the number of retransmissions becomes greater than this value, SCTP aborts the initialization of the association and reports the error to the SCTP user. Note: Maximum Initial Retransmissions parameter can be applied to associations in COOKIE-WAIT or COOKIE-ECHOED states in case of module reconfiguration. (states description can be found in [E1] and [E2]) According to the [E2], this parameter is recommended to be equal to 8.
Maximum Shutdown Retransmissions in number of attempts	Min: 1 Max: 20 Rec: 5 Def: -	The behavior depends on Reconfiguration Settings value.	The maximum number of retransmissions of SHUTDOWN chunks or the maximum number of retransmissions of SHUTDOWN_ACK during the shutdown of an association. If the number of retransmissions becomes greater than this value, SCTP aborts the graceful shutdown procedure and closes the association, but ABORT chunk is not sent. According to the [E2], this parameter is suggested to be equal to Assoc.Max.Rtx.
Heartbeat Interval in milliseconds	Min: 1 000 Since R10M: Min: 10 Max: 1 800 000 Rec: 30 000 Def: -	The behavior depends on Reconfiguration Settings value.	Affects a duration of time interval between cyclic heartbeats. According to the Heartbeat Status SCTP starts "Heartbeat Interval" timer per association or per IP path. Regular heartbeat is sent on an IP path if no reliable path availability indication has been received from data or heartbeat within the current heartbeat period and there is no outstanding data which can generate reliable path availability indication (see [E1] for more details). Heartbeat period is RTO interval + Heartbeat Interval, where Heartbeat interval is chosen as the maximum between zero and this configuration parameter recalculated with HB Reduce Rate, Smooth Factor and random variation within +/- (RTO interval)/2. HEARTBEAT_ACK chunk for a specific heartbeat is expected within pathRTO. If HEARTBEAT_ACK does not arrive in time, the heartbeat is considered unacknowledged and RTO of its IP path is doubled (which is termed backoff in [E2]). The next heartbeat is sent after heartbeat interval period. A small value of this parameter can help to detect unreachable addresses sooner than higher values, though sending heartbeats too often could lead to performance penalty. According to the [E2], this parameter is recommended to be equal to 30 000 milliseconds. It is recommended to configure the value of HB interval parameter to be greater than Maximum RTO.
HB Reduce Rate Available since R9C	Min: 0 Max: 100 Rec: 50 Def: 0	The behavior depends on Reconfiguration Settings value.	This parameter sets the number of percents on which current HB interval should be decreased (comparing to current value) with each new HB attempt in case of HB ACK was not received. The HB interval is reduced only while IP path is active, once IP path inactivity has been discovered, the HB interval reset to initial value for that path.
Heartbeat Status	Min: 0 Max: 1 Since R10M: Max: 3 Rec: 1 Def: - Since R10O: Max: 15 Rec: 15 Def: -	The behavior depends on Reconfiguration Settings value.	Bitmask defines SCTP path monitoring by regular heartbeats: bit 0 (Activation): 0 - path monitoring is disabled. SCTP does not send regular heartbeats at all. 1- path monitoring is enabled. Note: If bit 0 is equal to 0, bit 1 has no sense and ignored by SCTP. bit 1 (Quicker Failure Detection): 0 - Quicker Failure Detection is disabled. SCTP starts "Heartbeat Interval" timer per association and send one heartbeat via only one idle IP path each time when the timer is expired. 1 - Quicker Failure Detection is enabled. SCTP starts "Heartbeat Interval" timer per IP path and sends one heartbeat via particular idle IP path each time when the timer is expired independently on other IP paths. If bit 1 is set to 1, it is recommended to configure non-zero Smooth Factor. bit 2 (HBs with PMTU size): 0 – SCTP sends HBs without extension by PAD chunk. 1 – SCTP sends HBs with PMTU size of the affected IP path by using bundled PAD chunk. Note: if bit 0 is set to 0 and bit 2 is set to 1, SCTP sends demand HBs and Unreachable IP Path Detecting HBs with PMTU size and does not send regular HBs. Note: if bit 0 is set to 1 and bit 2 is set to 1, SCTP sends regular HBs, demand HBs and Unreachable IP Path Detecting HBs with PMTU size.
			bit 3 (HBs bundled with PAD chunks): 0 – Every regular HB chunk is bundled with PAD chunk. 1 – Regular HB chunk is bundled with PAD chunk only when it is sent on a path with non-zero t3 counter. Note: Bit 3 is applied only to regular HBs. Note: if bit 2 is set to 0, then bit 3 is ignored. bits 4-7: not used.
Hb.Max.Burst Available since R9	Min: 0 Max: 2³²-1 Rec: 1 Def: 1	Yes, applies only to newly established associations	Limits number of HB which could be sent at the same time for path probing. Maximum value is not limited for configuration file. Zero value of the parameter means that “Path probing” mechanism shall not be enabled for associations. SCTP will not use “ Hb.Max.Burst” value more than the number of IPpaths. For more details see [E2] According to the [E2], this parameter is recommended to be equal to 1. Note: If Hb.Max.Burst value is equal to 0, but the Unreachable IP Paths Detecting procedure was enabled ( Number of Attempts to Probe Unreachable IP Paths is greater than 0), configuration will be rejected.
Initial HB Interval in milliseconds Available since R9	Min: 0 Max: 1 800 000 Rec: “ Heartbeat interval / 6” Def: “ Heartbeat interval / 6”	Yes, applies only to newly established associations	Defines the time between bursts of HEARTBEAT chunks during initial path-probing. A period for acceptance of the corresponding HEARBEAT_ACK chunks is RTO. During this interval they are considered as not stale. Limits intensity of the HB after association start-up for path probing. Frequent heartbeats may affect traffic flow. It is recommended to configure the value of Initial HB interval parameter to not greater than the value of HB interval parameter. Also, it is recommended to configure the value of Initial HB interval parameter to be greater than Maximum RTO.
Smooth Factor in percentage Available since R9	Min: 0 Max: 100 Rec: 50 Def: 0	The behavior depends on Reconfiguration Settings value.	Allows smooth heartbeat messages in time. It is recommended to setup non-zero smooth factor, if a lot of associations could be started at the same time or if bit 1 of HB status is set to 1. Smoothed heartbeats allow avoiding unexpected impact on traffic flow. See [E1] (chapter 2) for more details. Parameter is used during whole life-time of an association.
Maximum Incoming Streams (MIS)	Min: 1 Max: 65 535 Rec: SS7 ITU: 17; SS7 ANSI: 257 Def: -	Yes, applies only to new endpoints	Maximum number of incoming streams for an association.

The size of the buffer used to store user-data pending to send or retransmit in an association. The maximum amount of data that SCTP can store before discarding user messages. Note: In case if this buffer becomes overflowing then the SCTP layer issues an indication SCTP_SEND_FAILURE_ind to the user on every new received SCTP_SCTP_SEND_req (see [E1] (chapter 4.2.2 Congestion Reporting) for details). Note: See also: N and N percentage.

The value of the threshold used to ask the SCTP user to stop the delivery of data on an association. Once N or more bytes are queued and are pending to send, the SCTP layer issues an indication SCTP_CONGESTION_IND to the user (see [E1] (chapter 5) for details). The value of N should be less than M (see above) in order to be an effective threshold.
N Percentage in percentage	Min: 1 Max: 100 Rec: 85 Def: 85	The behavior depends on Reconfiguration Settings value.	The value of the threshold used to notify the SCTP user that the delivery of data on an association can be resumed. Once the size of M-buffer becomes less than N* N percentage/100, the SCTP layer issues an indication SCTP_CONGESTION_CEASE_ind to the user (see [E1] (chapter 5) for details). At 100 percentage the primitive will be sent as soon as the buffer occupancy goes below N.
Initial RWND in number of bytes	Min: must be larger than 1 500 Min: must be larger than 1 300 Since R10: Min: must be larger than 1 500 Since R10: Min: must be larger than 1 300 Max: 1 048 576 Rec: 8192 Def: -	The behavior depends on Reconfiguration Settings value. If Reconfiguration Settings parameter is equal to one or two, and the value of Initial RWND is decreased then the new value of the parameter will be applied only to newly established associations; if the value of Initial RWND is higher then the previously set configuration value, it will be applied to both existing and newly established associations.

Arwnd Update Threshold in percents Available since R9C	Min: 0 Max: 100 Rec: 50 Def: 0	The behavior depends on Reconfiguration Settings value.	This parameter sets the part of Initial RWND which is required to be released in the incoming buffer in order to force additional SACK chunk. The additional SACK is always bundled and sent together with HEARTBEAT chunk. Value 0 means that no additional SACK chunks will be sent. See description of this parameter in [E1] for more details.
Maximum Number Of OOB Packets	Min: 1 Max: 1 6384 Rec: 100 Def: 100	Yes, applies to module immediately.	Sets the threshold for out of the blue packets received.

SACK Timer in milliseconds	Min: 0 Max: 500 Rec: 40 Def: 200	The behavior depends on Reconfiguration Settings value.	Number of milliseconds for the SACK chunk to be sent after a DATA chunk reception. If this value is equal to zero each SCTP packet will be SACKed immediately and the SACK Frequency parameter value will not have an effect. According to the [E2], this parameter is suggested to be equal to 200 ms.
SACK Frequency	Min: 1 Max:5 Rec: 2 Def: 2	The behavior depends on Reconfiguration Settings value.	The number of SCTP packets which must be received by the SCTP module before it sends a SACK chunk. This value has no effect if “ SACK Timer” is equal to zero. According to the [E2], this parameter is suggested to be equal to 2.
Bundling Status	Min: 0 Max: 1 Rec: 1 Def: 0	The behavior depends on Reconfiguration Settings value.	Enables DATA chunks bundling: 0 - disabled, 1 - enabled.

Bundling Timer in milliseconds	Min: 0 Max: 10 000 Rec: 0 Def: 0	The behavior depends on Reconfiguration Settings value.	Configures the delay to bundle DATA chunks. In the scope of Adaptive Bundling feature (see Bundling Threshold parameter) it also defines interval to measure user traffic load.
Path Selection Adjustment Available since R9	Min: 0 Max: 7 Rec: 3 Def: 1	The behavior depends on Reconfiguration Settings value.	Bitmask which defines path selection properties bit 0 (Path selection scheme): 0: Path selection on scheme A ("PEER") 1: Path selection on scheme B ("PATH") Note: If path selection scheme A ("PEER") is used, all other bits must be set to zero. If path selection scheme B ("PATH") is used, additional features defined by following bits may be used: bit 1 (Primary Path Avoidance): 0: primary path avoidance is disabled 1: primary path avoidance is enabled This parameter allows to avoid normal data transmission on the primary path, in case, if the latest attempt to send data on it fails. The primary path is used as long as path error counter does not exceed Primary.Path.Max.Rtx. bit 2 (Volatile mode): 0: volatile mode is disabled 1: volatile mode is enabled In "Volatile mode" current primary path is only changed when it fails. If "Volatile mode" is disabled, SCTP will also use preset primary path as current primary path as soon as it is probed by heartbeats. The parameters Minimum Activate Threshold, Maximum Activate Threshold and Activate Threshold Factor are ignored in "Volatile mode". bits 3-7: not used.
PMTU in number of bytes	Min: ” Minimum IPv4 PMTU” Max: ” Maximum IPv4 PMTU” Rec: 1 480 (for Ethernet protocols) Rec: 1 280 (for Ethernet protocols) Def: -	The behavior depends on Reconfiguration Settings value.	Describes PMTU on IPv4 paths. Path Maximum Transmission Unit, the maximum number of bytes of an IP datagram that can be transferred in a single unit over a specific path in an IPv4 network. If an IP datagram exceeds the PMTU, normally it will be either fragmented or dropped by IP layer. In the case of recommended configured value any user message will be fragmented by 1452 bytes and presented as a queue of DATA chunks. So, if this parameter is greater then 1480, it is strongly recommended to activate bundling. In the case of recommended configured value any user message will be fragmented by 1252 bytes and presented as a queue of DATA chunks. So, if this parameter is greater then 1280, it is strongly recommended to activate bundling. PMTU can be more than CP buffer size (which used to send messages).
IPv6 PMTU Available since R9	Min: 1 240 Max: “ Maximum IPv6 PMTU” Since R10T if PMTUD Accuracy does not activate PMTU discovery process: Max: Size of outgoing IP buffer - 40 Rec: 1 240 Def: “PMTU”	The behavior depends on Reconfiguration Settings value.

ECN capability Available since R10	Min: 0 Max: 1 Rec: 1 Def: 0	Yes, will be applied only to newly established associations.	Determines if the support for Explicit Congestion Notification (ECN) is enabled. 0 - SCTP is not ECN capable 1 - SCTP is ECN capable If ECN capability is equal to one and needed for ECN feature socket options are not supported by IP layer (see E1), such configuration will be rejected.
DNS Support Available since R10	Min: 0 Max: 3 Rec: 3 Def: 0	Yes, will be applied only to newly established associations.	This parameter defines support of DNS Hostnames: Bit 0 defines support of DNS Hostnames in user primitives (0 - Not supported, 1 - Supported). Bit 1 defines support of DNS Hostnames in INIT and INIT ACK chunks (0 - Not supported, 1 - Supported).
Stream Statistic Flag Available since R10	Min: 0 Max: 1 Rec: 0 Def: 0	Yes, will be applied only to newly established associations.	Indicates if collection of the statistic per stream is active or not: 0 - inactive 1 - active If the statistic collection per stream was activated, it affects memory. Memory consumption in this case is described in E1.
Block Cross-paths Flag Available since R10A and R9E (for SCTP R9 configuration files)	Min: 0 Max: 1 Rec: 0 Def: 0	The behavior depends on Reconfiguration Settings value.	Defines if SCTP should block cross-paths for traffic (including control chunks). 0 - do not block cross-paths 1 - block cross-paths Cross-paths are defined as paths which have the same local IP address or the same remote IP address as the primary path Note: Cross-paths are blocked only after association establishment. Note: Block Cross-paths Flag parameter take effect if only Cross Paths Mode parameter is equal to zero.
Minimum Activate Threshold Available since R10B	Min: 1 Max: Maximum Activate Threshold Rec: - Def: 1	The behavior depends on Reconfiguration Settings value.	Minimum number of consecutive successful heartbeats needed to switch back to primary path. Defines the initial value of Activate threshold parameter of an association path. This parameter is ignored if bit 2 of " Path Selection Adjustment" is set to 1 (Volatile mode is ON). Note: If during reconfiguration/update of Minimum Activate Threshold it becomes greater than current Activate threshold, Activate threshold will be increased to new value of Minimum Activate Threshold
Maximum Activate Threshold Available since R10B	Min: Minimum Activate Threshold Max: 65535 Rec: - Def: 1	The behavior depends on Reconfiguration Settings value.	Maximum possible number of consecutive successful heartbeats needed to switch back to primary path. This parameter is ignored if bit 2 of " Path Selection Adjustment" is set to 1 (Volatile mode is ON). Note: If this value is greater than 1, it will take longer time to switch back to primary path. Note: If during reconfiguration/update of Maximum Activate Threshold it becomes less than current Activate threshold, Activate threshold will be decreased to new value of Maximum Activate Threshold
Activate Threshold Factor Available since R10B	Min: 0 Max: 255 Rec: 0 Def: 255	The behavior depends on Reconfiguration Settings value.	This parameter (n) defines the backoff factor (F) used to update the current value of consecutive successful heartbeats needed to switch back to the preset primary path. The backoff factor (F) is used each time a switch back to primary path is performed and is calculated from the Activate Threshold Factor (n) by means of the formula F = 2 - n / 255. Note: After multiplying to the backoff factor, rounding of the new Activate threshold will be done to the nearest integer value. This parameter is ignored if bit 2 of " Path Selection Adjustment" is set to 1 (Volatile mode is ON).
Primary.Path.Max.Rtx Available since R10D	Min: 0 Max: Path.Max.Rtx Rec: - Def: 0	The behavior depends on Reconfiguration Settings value.	Defines the Maximum value of the error counter of the current primary path in case of enabled Primary Path Avoidance in Path Selection Adjustment. If the error counter of the primary path exceeds this value, SCTP will choose another current primary path. If Primary Path Avoidance is disabled, this parameter will be ignored. It is recommended to configure Primary.Path.Max.Rtx parameter is less than Path.Max.Rtx. Otherwise Primary Path Avoidance becomes disabled.
Number of Attempts to Probe Unreachable IP Paths Available since R10J	Min: 0 Max: 255 Rec: Path.Max.Rtx +1 Def: 0	The behavior depends on Reconfiguration Settings value.	This parameter defines the number of unsuccessful successive HBs after which an IP path is marked as "unreachable" in the Unreachable IP Paths Detecting procedure. Value 0 means that SCTP does not try to detect unreachable IP paths (the Unreachable IP Paths Detecting procedure is disabled). Note: the value of the Heartbeat Maximum Burst parameter cannot be equal to 0 if the Unreachable IP Paths Detecting procedure was enabled.
Probing Unreachable IP Paths Interval in milliseconds Available since R10J	Min: 0 Max: 2³²-1 Rec: 7200000 Def: 0	The behavior depends on Reconfiguration Settings value.	This parameter defines the interval between Unreachable IP Paths Detecting procedures. Value 0 means that SCTP tries to detect unreachable IP paths only one time. It is not recommended to set the value of this parameter less than Initial HB Interval. Note: Parameter makes sense only if Number of Attempts to Probe Unreachable IP Paths is nonzero.
DSCP Available since R10N	Min: 0 Max: 64 Rec: - Def: 64	The behavior depends on Reconfiguration Settings value.	This value represents the "Differentiated Service Code Point" related to the Quality of Service. Used value can be different from this value.

Zero RWND Supervision Timer in milliseconds Available since R10R	Min: 0 Max: 2³²-1 Rec: 5000 to 120000 Def: 0	The behavior depends on Reconfiguration Settings value.	This timer is used for supervision of the period of time in which peer's RWND is closed. SCTP starts this timer when the calculated peer's RWND is equal to 0. SCTP stops this timer when it is notified that peer's RWND is open. SCTP ungracefully closes the association at the timer expiration. If the value is equal to 0, SCTP does not start the timer. If the value is equal to 1, SCTP calculates the duration of the timer by using the following formula: 4 * Maximum RTO * Assoc.Max.Rtx. Note: It is not recommended to configure the timer value less than Maximum RTO * Assoc.Max.Rtx.
Multiple Fast Retransmit Available since R10U	Min: 0 Max: 1 Rec: 0 Def: 1	The behavior depends on Reconfiguration Settings value.	Defines whether Multiple Fast Retransmit procedure is enabled or not: 0 – disabled; 1 – enabled; Value 0 makes SCTP to follow E2.
Slow Start CWND Increment Factor Available since R10W	Min: 100 Max: 200 Rec: 200 Def: 100	The behavior depends on Reconfiguration Settings value.	This parameter defines maximum CWND increment factor during slow start phase in percent from the path MTU. In slow start phase CWND is increased by the lesser of: 1) the total size of the previously outstanding DATA chunk(s) acknowledged; 2) current path MTU multiplied by Slow Start CWND Increment Factor and divided by 100. Value 100 makes SCTP to follow E2. It is recommended to configure this parameter in steps of 10% (100, 110, 120 and so on).
Time Critical Service Available since R10Y	Min: 0 Max: 2 Rec: 0 Def: 0	The behavior depends on Reconfiguration Settings value.	Represents Time Critical Service mode: 0 – Service is disabled. 1 – The stream 0 is dedicated for non-time critical data; the rest of the streams are dedicated for time critical data. 2 – The stream 0 is dedicated for time critical data; the rest of the streams are used for non-time critical data. Note: This mechanism allows SCTP to transmit traffic through the same association with different delay and bundling behavior depending on the specification by the user as the traffic being either time critical or non-time critical. For more details see chapter “Time Critical Service” in [E1].
Maximum Initial CWND in number of PMTUs Available since R10Z	Min: 4 Max: 10 Rec: 10 on fast IP links, 4 on slow IP links Def: 4	The behavior depends on Reconfiguration Settings value.	This parameter defines maximum initial, restart and loss recovery CWND for SCTP associations. If bit 0 of parameter Maximum Initial CWND Operation Mode set to 1 (Initial window) initial CWND will be set as min (Maximum Initial CWND * Current PMTU, max(2 * Current PMTU, CWND_PLATEAU)), where CWND_PLATEAU equals •1460 * Maximum Initial CWND if Maximum Initial CWND is greater than 4. •1460 * 3 otherwise. If bit 1 of parameter Maximum Initial CWND Operation Mode set to 1 (Restart window) restart CWND will be set as max(CWND/2, min(Maximum Initial CWND * Current PMTU, max(CWND, 4 * Current PMTU))). If bit 2 of parameter Maximum Initial CWND Operation Mode set to 1 (Loss recovery window) loss recovery CWND will be set as max(CWND/2, min(Maximum Initial CWND * Current PMTU, max(CWND, 4 * Current PMTU))). Note: On the Management level, platform adaptation is recommended to provide simplified alternatives to configure initial CWND: 0: Initial, restart and loss recovery windows are 4Current PMTUs. 1: Initial window is 10Current PMTU, restart and loss recovery windows are 4Current PMTU. 2: N/A. 3: Initial, restart and loss recovery windows are 10Current PMTU.
Maximum Initial CWND Operation Mode Available since R10Z	Min: 0 Max: 7 Rec: 7 Def: 0	The behavior depends on Reconfiguration Settings value.	This parameter is a bit mask which defines in which cases the large CWND, defined by Maximum Initial CWND will be applied to: Bit 0: Initial window. 0 – Maximum Initial CWND will not be applied to initial window. 1 – Maximum Initial CWND will be applied to initial window. Bit 1: Restart window. 0 – Maximum Initial CWND will not be applied to restart window. 1 – Maximum Initial CWND will be applied to restart window. Bit 2: Loss recovery window. 0 – Maximum Initial CWND will not be applied to loss recovery window. 1 – Maximum Initial CWND will be applied to loss recovery window. Bits 3-7: Not used, must be zero. Note: On the Management level, platform adaptation shall provide simplified alternatives to configure initial CWND: 0: Initial, restart and loss recovery windows are 4* PMTUs. 1: Initial window is 10* PMTU, restart and loss recovery windows are 4* PMTU. 2: N/A. 3: Initial, restart and loss recovery windows are 10* PMTU.
Forced Activation of Parameters Available since R10AC	Min: 0 Max: 1 Rec: 0 Def: 0	The behavior depends on Reconfiguration Settings value.	Defines whether Forced Activation of Parameters is enabled: 0 – forced activation is disabled, 1 – forced activation is enabled. It means that SCTP will ungracefully close an association (send ABORT to the peer and SCTP_COMM_LOST_ind to the user), if any of the following parameters is reconfigured or updated: Maximum Incoming Streams, Maximum Outgoing Streams, Initial RWND (if decreased), ECN Capability, DNS Support, Stream Statistic Flag.
Bi-directional Support Only Available since R10AD	Min: 0 Max: 1 Rec: - Def: 0	The behavior depends on Reconfiguration Settings value.	Defines whether Bi-directional Support Only is enabled: 0 – bi-directional support only is disabled, 1 – bi-directional support only is enabled. It means that SCTP will enable the following behavior: SCTP does not clear the IP path error counter if SACK is received on not the same IP path where DATA was sent. SCTP silently ignores incoming HB ACK if it is received on not the same IP path where HB was sent. SCTP silently ignores incoming INIT ACK if it is received on not the same IP path where INIT was sent. SCTP silently ignores incoming COOKIE ACK if it is received on not the same IP path where COOKIE ECHO was sent. Bi-directional Support Only adds robustness against a receiver side which does not respond on chunks received on cross paths or responds but only on straight paths.
Cross Paths Mode Available since R10AI	Min: 0 Max: 2 Rec: - Def: 0	The behavior depends on Reconfiguration Settings value. Reconfiguration from 2 to 1 is never applied to an existing association if the sum of IP paths exceeds 16, syslog is used to report the case. Reconfiguration is never applied to an association that is being established.	Defines Cross Paths mode: 0 – Cross to Primary Paths Blocking controlled by Block Cross-Paths Flag. 1 – Cross paths are enabled. 2 – Cross paths are disabled. Note: Cross Paths modes 1 and 2 are supported for path selection scheme B “PATH” only. SCTP configuration will be rejected if Path Selection Adjustment has zero value and Cross Paths Mode has non-zero value. In comparison with Cross to Primary Paths Blocking, Cross Paths modes 1 and 2 have some differences: SCTP defines straight and cross paths differently; SCTP does not allow user requested HB to be sent through disabled cross path; SCTP disables use of cross paths when the number of IP paths exceeds 16.
Bundling Threshold Available since R10AJ	Min: 0 Max: 100 Rec: - Def: 0	The behavior depends on Reconfiguration Settings value.	If non-zero, it enables Adaptive Bundling feature and defines a part of association’s MTU in percent which is compared by SCTP with the user’s traffic rate per Bundling Timer to decide whether to bundle DATA chunks with delay or not. For more details about the feature see [E1]. Note: This parameter makes sense only if Bundling Status and Bundling Timer parameters have non-zero values. Note: Value 100 is optimal in most cases where latency on low traffic is critical, but there can be sense to tune it for particular purposes and environment.
Configuration Group parameters must be repeated (Number Of Optional Configuration Groups + 1) times.
Number Of Remote Endpoint Blocks Available since R10N	Min: 0 Max: 65535 Rec: - Def: 0	Yes, takes effect on newly established associations only.	Represents the number of blocks with remote endpoint information which follow. Each block is used to associate incoming association (which is established by the remote side) with Configuration Group. If “ Number Of Remote Endpoint Blocks” is equal to 0, SCTP uses Configuration Group of the local endpoint which is connected with the incoming association during establishment. All blocks are listed after the parameter “ Number Of Remote Endpoint Blocks” and repeated “ Number Of Remote Endpoint Blocks” times. All blocks follow one after another without any dividers. It is recommended to configure Remote Endpoint Blocks in the following order: first, blocks with IP addresses which do not have wildcards, then blocks with IP addresses which have wildcards.

The format of the IP address should be of Internet Standard format: "a.b.c.d", example 150.168.200.18 for IPv4 addresses or "a:b:c:d:e:f:g:h", example 2031:0:130F:0:0:9C:8A:130F for IPv6 addresses. Note: IPv6 addresses in the compressed format are allowed, example: 2031:0:130F::9C:8A:130F. Note: wildcards (* or ?) are allowed in IP addresses. * means any combination of decimal (in IPv4) or hexadecimal (in IPv6) numbers; ? means any decimal (in IPv4) or hexadecimal (in IPv6) numbers. DNS Hostname. Text string composed of the alphabet (A-Z), digits (0-9), minus sign (-), and period (.). No blank or space characters are permitted as a part of the name. The first character must be an alpha or digit character. The last character must not be a minus sign. DNS Hostname must not be in #.#.#.# dotted-decimal form. It is recommended to use wildcards in order to decrease the number of IP addresses and search time in SCTP.
The field Remote IP address or DNS Hostname must be repeated Number of Remote Addresses times.

Defines how SCTP shall handle incoming INIT chunk matched by Remote Port and Remote IP address or DNS Hostname: 0 - Use Configuration Group defined in Configuration Group ID for the association establishment. 1 - Use Configuration Group defined for the related endpoint for the association establishment. 2 - Drop incoming INIT chunk.
Match Type Available since R10S	Min: 0 Max: 1 Rec: - Def: 0	Yes, takes an effect on newly received INIT chunks.	Defines addresses matching type: 0 (ALL) - All addresses received in INIT chunk should be matched with addresses defined in Remote IP address or DNS Hostname. 1 (ANY) - At least one address received in INIT chunk should be matched with address defined in Remote IP address or DNS Hostname.
Remote Endpoint Block parameters must be repeated Number Of Remote Endpoint Blocks times.
