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:
To do...
Use the command...
Remarks
Enter system view

—
Create a multicast MAC
address entry
mac-address multicast
mac-address interface
interface-list vlan vlan-id
Required
The mac-address argument
must be a multicast MAC
address.
Follow these steps to configure a multicast MAC address entry in Ethernet port view:
To do...
