Configuring a Multicast MAC Address Entry

In Layer 2 multicast, the system can add multicast forwarding entries dynamically through a Layer 2

multicast protocol. Alternatively, you can statically bind a port to a multicast MAC address entry by

configuring a multicast MAC address entry manually.

Generally, when receiving a multicast packet for a multicast group not yet registered on the switch, the

switch will flood the packet within the VLAN to which the port belongs. You can configure a static

multicast MAC address entry to avoid this.

Follow these steps to configure a multicast MAC address entry in system view:
