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.
