Command Usage

This command displays information for multicast groups learned via IGMP, not static groups.

If the switch receives an IGMP Version 1 Membership Report, it sets a timer to note that there are Version 1 hosts present which are members of the group for which it heard the report.

If there are Version 1 hosts present for a particular group, the switch will ignore any Leave Group messages that it receives for that group.
