Description: 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.

What is ctIGMPExtCacheVersion1HostTimer?

In the extended cache table, counts down the seconds until the switch stops assuming legacy IGMPv1 hosts remain on this group/subnet, during which it continues to ignore IGMPv2 Leave messages for compatibility.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.3.5.1.7.1.7
snmpwalk -v2c -c public <target> CTRON-IGMP-MIB::ctIGMPExtCacheVersion1HostTimer

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.3.5.1.7.1.7.1
snmpget -v2c -c public <target> CTRON-IGMP-MIB::ctIGMPExtCacheVersion1HostTimer.1
