no ip igmp static-group A.B.C.D

(for example, 10.0.0.1), as the allowable range of addresses included in
the multicast group.

Defaults

None

Command Modes

VE interface configuration mode

VLAN interface configuration mode

Description

Use this command to create IGMP static group membership to test multicast forwarding without a
receiver host. When you enable IGMP static group membership, data is forwarded to an interface
without receiving membership reports from host members. Using ip igmp static-group, packets to
the group are fast-switched out of a specific interface. Static group membership entries are
automatically added to the IGMP cache and PIMmcache table.

Usage Guidelines

Enter no ip igmp static-group A.B.C.D to restore the default setting for the specified group address.

Examples

To create a static port-channel group for a specific VLAN interface:

switch(config)# interface vlan 100

switch(config-Vlan-100)# ip igmp static-group 225.1.1.1 interface port-channel 60

To reset a static group on a specific VLAN interface to the default settings:

switch(config)# interface vlan 100

switch(config-Vlan-100)# no ip igmp static-group 225.1.1.1
