Chapter 4 Multicast MAC Address Entry
Configuration
4-2
Operation
Command
Description
Create a multicast MAC
address entry.
mac
-address multicast
mac-address
vlan vlan-id
Required
The
mac-address
argument must be a
multicast MAC address
The vlan-id argument is
the ID of the VLAN to
which the port belongs.
Note:
z
If the multicast MAC address entry to be created already exists, the system gives
you a prompt.
z
If a multicast MAC address is added manually, the switch will not learn this multicast
MAC address again through IGMP Snooping. The undo mac-address multicast
command is used to delete the multicast MAC address entries created by the
mac
-address multicast command manually; however, it cannot be used to delete
the multicast MAC address entries learned by the switch.
z
If you want to add a port to a multicast MAC address entry created through the
mac
-address multicast command, you must delete this entry first, create this entry
again, and then add the specified port to the forwarding ports of this entry.
z
The system does not support adding multicast MAC addresses to IRF ports. If a port
is already an IRF port, the system will prompt that you cannot add multicast MAC
addresses to this port.
z
You cannot enable link aggregation on a port on which you have configured a
multicast MAC address; and you cannot configure a multicast MAC address on an
aggregation port.
