Usage Guidelines

Usage Scenario

IGMP snooping is a basic Layer 2 multicast function that forwards and controls multicast traffic at the data link layer. IGMP snooping 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.

Prerequisites

An AP wired port profile has been created.

Precautions

The AP wired interfaces added to an Eth-trunk interface do not support this function.

When multicast services are enabled, the multicast services may be affected if rate limit for multicast packets is enabled on an AP. In this case, you are advised to run the traffic-optimize broadcast-suppression rate-threshold (AP system profile view) command to adjust the rate limit threshold for multicast packets.

Example

# Enable IGMP snooping on AP wired port profile p1.
<HUAWEI> system-view
[HUAWEI] wlan
[HUAWEI-wlan-view] wired-port-profile name p1
[HUAWEI-wlan-wired-port-p1] igmp-snooping enable
