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.
