Usage Guidelines
Usage Scenario
After Layer 2 multicast is enabled on the wireless access controller, the wireless access controller maintains a Layer 2 multicast forwarding table. When receiving a multicast packet, the wireless access controller searches the Layer 2 multicast forwarding table for the outbound interface based on the multicast address of the packet. The wireless access controller determines the outbound interface based on the IP multicast address or IP multicast MAC address, depending on the configured Layer 2 multicast forwarding mode.
To check which Layer 2 multicast forwarding mode is used, run the display l2-multicast forwarding-mode command.
Precautions
You can change the forwarding mode using the l2-multicast forwarding-mode command.
