4.Enable IGMPv3 Snooping (optional). ex2500(config)# ip igmp snoop igmpv3 enable
5.View dynamic IGMP information.
ex2500# show ip igmp groups
Note: Local groups (224.0.0.x) are not snooped/relayed and will not appear.

These commands display information about IGMP Groups and Mrouters learned by the switch.
Static Multicast Router
A static multicast router (Mrouter) can be configured for a particular port on a particular VLAN. A static Mrouter does not have to be learned through IGMP Snooping. Any data port can accept a static Mrouter.
When you configure a static Mrouter on a VLAN, it replaces any dynamic Mrouters learned through IGMP Snooping.
Use the following procedure to configure a static multicast router (Mrouter):
1.For each Mrouter, configure a port or trunk group (1 through 24 or po1 through po24), VLAN (1 through 4094), and version (1 through 3).
ex2500(config)# ip igmp mrouter 5 1 2
The IGMP version is set for each VLAN, and cannot be configured separately for each Mrouter.
2.Verify the configuration. ex2500(config)# show ip igmp mrouter
