1   Description

This instruction describes how to configure DNS support on the SS7 SCTP product using the Ericsson Command-Line Interface (ECLI).

The following parameter can be configured:

• Address of DNS server
• DNS suffix
• DNS time-out
• Support of DNS in SCTP protocol

2   Procedure

2.1   Configure SCTP DNS

Prerequisites

• No documents are required.
• No tools are required.
• The following conditions must apply:
  • An SctpProfile Managed Object (MO) exists.
  • An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

Steps

1. Navigate to the CommonParts MO, for example:

   >ManagedElement=1,Transport=1,SctpSystem=1,CommonParts=1

2. Enter Config mode:

   (CommonParts=1)>configure

3. Set the DNS Server Address string, for example:

   (config-CommonParts=1)>dnsServerIpAddress="8.8.8.8"

4. Set the DNS Suffix string (optional), for example:

   (config-CommonParts=1)>dnsSuffix=""

5. Set DNS time-out in 1/10 of seconds (the value 1 means 100ms), for example:

   (config-CommonParts=1)>timeoutHostName=30

6. Navigate to the SctpProfile MO, for example:

   (config-CommonParts=1)>dn ManagedElement=1,Transport=1,Sctp=1,SctpProfile=1

7. Set DNS Support in SCTP:

   (config-SctpProfile=1)>dnsSupport=<value>

   Possible values are NOT_SUPPORTED, IN_USER_PRIMITIVES_ONLY, IN_INIT_AND_INIT_ACK_CHUNKS_ONLY, and SUPPORTED.

8. Commit the changes:

   (config-SctpProfile=1)>commit

9. Verify the changes in the CommonParts MO, for example:

   >show ManagedElement=1,Transport=1,SctpSystem=1,CommonParts=1

   The following is an example output:

   CommonParts=1 dnsServerIpAddress="8.8.8.8" timeoutHostName=30

10. Verify the changes in the SctpProfile MO, for example:

    >show ManagedElement=1,Transport=1,Sctp=1,SctpProfile=1

    The following is an example output:

    SctpProfile=1 dnsSupport=SUPPORTED
