Adding an interface to a multicast group
You can manually add an interface to a multicast group. This is useful in the following cases:
• Hosts attached to the interface are unable to add themselves as members of the group using
IGMP.
• There are no members for the group attached to the interface.
When you manually add an interface to a multicast group, the device forwards multicast packets
for the group but does not itself accept packets for the group.
You can manually add a multicast group to individual ports only. If the port is a member of a virtual
routing interface, you must add the ports to the group individually.
To manually add a port to a multicast group, enter a command such as the following at the
configuration level for the port.
Brocade(config-if-e10000-1/1)# ip igmp static-group 224.2.2.2
This command adds port 1/1 to multicast group 224.2.2.2.
To add a port that is a member of a virtual routing interface to a multicast group, enter a command
such as the following at the configuration level for the virtual routing interface.
Brocade(config-vif-1)# ip igmp static-group 224.2.2.2 ethernet 5/2
This command adds port 5/2 in virtual routing interface 1 to multicast group 224.2.2.2.
Syntax: [no] ip igmp static-group ip-addr [ethernet slot/portnum]
The ip-addr parameter specifies the group number.
The ethernet slot/portnum parameter specifies the port number. Use this parameter if the port is a
member of a virtual routing interface, and you are entering this command at the configuration level
for the virtual routing interface.
Manually added groups are included in the group information displayed by the following
commands:
• show ip igmp group
• show ip pim group
