Traffic Profile

Procedure

Create a traffic profile.

Choose Configuration > Wireless Services > Profile > Wireless Service > Traffic Profile. The Traffic Profile List page is displayed.
Click Create. The Create Traffic Profile page is displayed.
Enter the name of the new traffic profile in Profile name.
To copy all parameters from another profile to the new profile, select the name of the profile in Copy parameters from other profiles. If None is selected, parameters are not copied from another profile.
Click OK. The parameter setting page of the new traffic profile is displayed.

Set parameters for creating a traffic profile. Table 1 describes the parameters for creating a traffic profile.

**Table 1** Parameters for creating a traffic profile
Parameter	Description
Traffic Profile	Name of the traffic profile, which cannot be modified.
User isolation mode	User isolation mode.
Broadcast packet rate limit (pps)	Rate limit for broadcast packets. Broadcast packets are discarded if their rates exceed the rate limit.
Multicast packet rate limit (pps)	Rate limit for multicast packets. Multicast packets are discarded if their rates exceed the rate limit.
Unknown unicast packet rate limit (pps)	Rate limit for unknown unicast packets. Unknown unicast packets are discarded if their rates exceed the rate limit.
Packet filtering
Inbound ACL	ACL used to filter incoming packets.
Outbound ACL	ACL used to filter outgoing packets.
Re-marking
Re-marking Incoming Packets	Whether to re-mark the priority of incoming packets.
Re-marking Outgoing Packets	Whether to re-mark the priority of outgoing packets.
Uplink Priority Mapping on Air Interface Mapping from the 802.11e user priority to DSCP priority in the CAPWAP header when packets are sent from an AP to an AC.
Trust mode	Trusted priority on the air interface, which is the 802.11e or DSCP priority.
802.11e	802.11e user priority.
DSCP	DSCP priority of 802.11 packets.
Tunnel DSCP	DSCP priority in the CAPWAP header.
Downlink Priority Mapping on Air Interface Mapping from the 802.1p or DSCP priority of 802.3 packets to the 802.11e user priority when packets are sent to an AP from upper-layer devices.
Trust mode	Trusted priority on the air interface, which is the 802.1p or DSCP priority.
802.1p	802.1p priority of 802.3 packets.
Tunnel DSCP	DSCP priority in the CAPWAP header.
802.11e	802.11e user priority.
Rate Limit
STA upstream rate limit (Kbit/s)	Uplink rate limit for a STA.
STA downlink rate limit (Kbit/s)	Downlink rate limit for a STA.
VAP uplink rate limit (Kbit/s)	Uplink rate limit for all STAs on a VAP. The value of this parameter must be greater than the uplink rate limit set for a STA.
VAP downlink rate limit (Kbit/s)	Downlink rate limit for all STAs on a VAP. The value of this parameter must be greater than the downlink rate limit set for a STA.
Dynamic rate limit for STAs	Whether to enable dynamic rate limiting for a single STA in a VAP.
Rate limit threshold (Kbit/s)	Dynamic rate limit threshold for a single STA in a VAP. This parameter can be configured only when dynamic rate limiting for a STA is enabled.
Multicast
IGMP-Snooping	Whether to enable IGMP snooping.
Multicast Report/Leave Suppression	Whether to enable suppression of multicast Report/Leave packets. This parameter can be configured only when IGMP snooping is enabled.
MLD-Snooping	Whether to enable MLD snooping.
Multicast-to-unicast conversion	Whether to enable the function of converting multicast packets to unicast packets. You can enable the function of converting multicast packets to unicast packets in scenarios that have high requirements on multicast stream transmission, such as a high-definition video on-demand scenario. After the function is enabled, an AP listens on Report and Leave packets to maintain multicast-to-unicast entries. When sending multicast packets to the client, the AP converts the multicast packets to unicast packets based on the multicast-to-unicast entries to improve multicast stream transmission efficiency.
Air Interface Optimization
ARP proxy	Whether to enable ARP proxy.
ND proxy	Whether to enable ND proxy.
Broadcast & multicast to unicast	Function of converting broadcast or multicast packets to unicast packets on an air interface. If an air interface sends a large number of broadcast or multicast packets when being busy, the performance of the air interface will drop. To prevent this situation, you can configure the function of converting broadcast or multicast packets to unicast packets to reduce the number of broadcast or multicast packets transmitted on the air interface. This improves air interface performance at the price of increased CPU usage.
Sending packets that fail in broadcast & multicast to unicast conversion to all users	Whether to enable broadcast or multicast packets traverse to unicast. Enable the STA address learning function. Otherwise, this function cannot take effect.
Others
TCP MSS	Maximum segment size (MSS) of TCP packets in a traffic profile.
