| Multicast Filtering Commands

IGMP (Layer 3)

Interface Configuration (VLAN)

Group addresses within the entire multicast group address range can

be specified with this command. However, if any address within the

source-specific multicast (SSM) address range (default 232/8) is

specified, but no source address is included in the command, the

request to join the multicast group will fail unless the next node up the

reverse path tree has statically mapped this group to a specific source

address. Also, if an address outside of the SSM address range is

specified, and a specific source address is included in the command, the

request to join the multicast group will also fail if the next node up the

reverse path tree has enabled the PIM-SSM protocol.

If a static group is configured for an any-source multicast (*,G), a

source address cannot subsequently be defined for this group without

first deleting the entry.

If a static group is configured for one or more source-specific multicasts

(S,G), an any-source multicast (*,G) cannot subsequently be defined

for this group without first deleting all of the associated (S,G) entries.

Using the no form of this command to delete a static group without

specifying the source address will delete all any-source and source-

specific multicast entries for the specified group.

The switch supports a maximum of 16 static group entries.

The following example assigns VLAN 1 as a static member of the specified

multicast group.

Console(config)#interface vlan1

Console(config-if)#ip igmp static-group 225.1.1.1
