Cisco Cisco IOS Software Release 12.2(18)SXF

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.

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.

Reduces the number of commands required to administer devices that require many ip igmp 
static-group command configurations.

This procedure contains the following tasks:

 (required)

 (optional)

The IGMP Static Group Range Support feature is an enhancement that 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.

Perform this task to configure IGMP static group class maps and attach class maps to the 
ip igmp static-group command. 

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 

 section.
