Displaying IGMP Snooping Information

You can use various show commands to view information about IGMP snooping.

Use one of the following commands to view IGMP snooping information. The commands do not need to be entered in the specified order. Using these commands is optional and they can be entered in any order. For more information on the full list of show ip multicast commands, refer to the Ruckus FastIron Command Reference
