Traffic Profile
Overview
In a traffic profile, you can configure priority mapping on the wireless side, air interface performance optimization, traffic policing, and ACL-based packet filtering. The configurations in a traffic profile take effect only after it is bound to a VAP profile.
Priority mapping
Packets of different types have different priorities. For example, 802.11 packets sent by STAs carry user priorities or DSCP priorities, VLAN packets on wired networks carry 802.1p priorities, and IP packets carry DSCP priorities. Priority mapping must be configured on network devices to retain the priorities of packets that traverse different networks.
Traffic policing
To protect network resources and prevent network congestion, you can configure traffic policing to limit the rate of traffic entering a WLAN. In a traffic profile, you can configure rate limiting for upstream and downstream packets of all STAs or each STA on a VAP.
Traffic optimization
On a WLAN, a large number of wireless packets need to be forwarded, which may easily cause network congestion and degrade network performance. WLAN traffic optimization measures, such as traffic limit and multicast optimization, can be taken to adjust network traffic in real time, significantly reducing impact of burst data on the network and improving network performance.
ACL-based packet filtering
You can configure ACL-based packet filtering to enable a device to permit or deny packets matching ACL rules to control network traffic.
ACL-based packet priority re-marking
You can configure ACL-based packet re-marking priorities of packets matching ACL rules to implement differentiated services for wireless packets.

IGMP-Snooping |
IGMP snooping is a basic Layer 2 multicast function that forwards and controls multicast traffic at the data link layer. This function runs on a Layer 2 device and analyzes IGMP messages exchanged between a Layer 3 device and hosts to set up and maintain a Layer 2 multicast forwarding table. The Layer 2 device forwards multicast packets based on the Layer 2 multicast forwarding table. By default, the function is disabled. |
Multicast Report/Leave Suppression |
After this function is configured, a Layer 2 device forwards only one IGMP Membership Report message to the upstream device in the following scenarios: When the first member joins a multicast group or a host sends a Report message in response to an IGMP Query message, the Layer 2 device forwards a Report message to the upstream device. The upstream device then creates or maintains the matching forwarding entry based on the Report message. When the last member of a group leaves the group, the Layer 2 device forwards a Leave message to the upstream device. The upstream device then deletes the matching forwarding entry. This reduces the number of IGMP messages on the network. By default, the function is disabled. |
VAP multicast total bandwidth (kbit/s) |
Total multicast bandwidth on a VAP. If the idle multicast bandwidth on the VAP is insufficient, new users cannot access the multicast group. The value range is 1 to 10000000. |
Number of multicast group memberships on a VAP |
Number of multicast group memberships on a VAP. If this parameter reaches the maximum value, new users cannot access the multicast group. The value range is 1 to 1000. |
MLD-Snooping |
MLD snooping is an IPv6 Layer 2 multicast protocol. This protocol maintains information about the outbound interfaces of multicast packets by examining multicast protocol packets exchanged between the Layer 3 multicast device and user hosts. MLD snooping manages and controls multicast packet forwarding at the data link layer. By default, the function is disabled. |
Multicast-to-unicast |
You can enable the function of converting multicast packets to unicast packets in scenarios that have high requirements on multicast stream transmission, for example, high-definition video on-demand. After the function is enabled, an AP listens on Report and Leave packets to maintain multicast-to-unicast entries. The AP uses these entries to perform packet conversion when sending multicast packets to a client. This function helps to improve the efficiency of multicast stream transmission.
By default, the function is disabled. |
