ctIGMPExtCacheVersion1HostTimer
The time remaining until the local switch will assume that there are no longer any IGMP version 1 members on the IP subnet attached to this interface. Upon hearing any IGMPv1 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local switch ignores any IGMPv2 Leave messages for this group that it receives on this interface.
