• State—IGMP version on the interface
• ExpTim—Time, in seconds, at which the router stops polling for more members of
this group
• oldHTo—Time at which the router stops polling for more IGMPv1 members of a group.
If this value is 0, the interface has received no IGMPv1 reports for the group.
• Included Sources—Sources included in the multicast group
• Excluded Sources—Sources excluded from the multicast group
• Counts—Number of source-group mappings by version and state
• Example 1—Without OIF mapping
host1:boston#show ip igmp groups
