•Intf - The IP interface on this Switch that has received traffic directed to the IP multicast group address.

•Expire - The time remaining before this entry will be aged out. (The default is 260 seconds.)

•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. (The default is 400 seconds.) 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 mem- bers 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.
