 Note:
z If the multicast MAC address entry you are creating already exists, the system gives
you a prompt.
z The switch will not learn a manually added multicast MAC address by IGMP
Snooping. The undo mac-address multicast command can only remove manually
created multicast MAC address entries and cannot remove those learned by the
switch.
z To add a port to a manually created multicast MAC address entry, first remove the
entry, and then re-create the entry and specify the port as the forward port of the
entry.
z The system does not support the configuration of multicast MAC address on an IRF
port. If you do this, the system will give you a prompt that the multicast MAC address
configuration fails.
z You cannot enable port aggregation on a port where you have configured a
multicast MAC address; and you cannot configure a multicast MAC address on an
aggregation port.
