V1 Timer – The time remaining until the switch assumes that there are
◆
no longer any IGMP Version 1 members on the IP subnet attached to
this interface.
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.
