•
The ip igmp static-group command accepts an IGMP static group class map for the
class-map-name argument, regardless of whether the class map configuration exists. If a class map
attached to an interface does not exist, the class map remains inactive. Once the class map is
configured, all group entries associated with the class map are added to the IGMP cache and mroute
table.

If a class map is removed from an interface using the no form of the ip igmp static-group command,
all group entries defined in the class map are removed from the IGMP cache and mroute tables.

Benefits of IGMP Static Group Range Support
The IGMP Static Group Range Support feature provides the following benefits:
•
Simplifies the administration of devices that require many interfaces to be configured with many
different ip igmp static-group command configurations by introducing the capability to configure
group ranges in class maps and attach class maps to the ip igmp static-group command.

Note
Although the IGMP Static Group Range Support feature uses the MQC to define class maps, the
procedure for configuring IGMP static group class maps is different from the normal procedure used to
create class maps for configuring QoS traffic policies. For more information about IGMP static group
class maps, including configuration guidelines, see the
