Monitoring IGMP Snooping and MVR
Monitoring IGMP Snooping Information
You can display IGMP snooping information for dynamically learned and statically configured router ports
and VLAN interfaces. You can also display MAC address multicast entries for a VLAN configured for IGMP
snooping.

• user—Displays only the user-configured multicast entries.
show ip igmp snooping groups [count
|dynamic [count] | user [count]]
