◆

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.
