Cisco IOS Release 12.2(18)SXF5
Verifying IGMP Static Group Range Support
Perform this optional task to verify the contents of IGMP static group class maps configurations, and to
confirm that all group entries defined in class maps were added to the IGMP cache and the mroute table
after you attach class maps to interfaces.

DETAILED STEPS
Step 1
show ip igmp static-group class-map [interface [type number]]
Use this command to display the contents of IGMP static group class maps and the interfaces using class
maps:
maps:
•
Specify the interface keyword to filter the output to display only the interfaces using class maps.
•
Specify the interface keyword and the type number arguments to filter the output to display only
the class map attached to a particular interface.
the class map attached to a particular interface.
The following is sample output from the show ip igmp static-group class-map command:
Router# show ip igmp static-group class-map
Class-map static1
Group address range 228.8.8.7 to 228.8.8.9
Group address 232.8.8.7, source address 10.1.1.10
Interfaces using the classmap:
Loopback0
Class-map static
Group address range 232.7.7.7 to 232.7.7.9, source address 10.1.1.10
Group address 227.7.7.7
Group address range 227.7.7.7 to 227.7.7.9
Group address 232.7.7.7, source address 10.1.1.10
Interfaces using the classmap:
Step 9
ip igmp static-group
class-map class-map-name
Example:
Router(config-if)# ip igmp static-group
class-map static1
Attaches an IGMP static group class map to the interface.
•
Once a class map is attached to an interface, all group
entries defined in the class map become statically
connected members on the interface and are added to
the IGMP cache and mroute table.

Step 10
Repeat Step 8 and 9, if you want to attach class maps
to additional interfaces.
