usrIgmpCacheVersion1HostTimer

Module: USR-IGMP-MIB

OID (symbolic): USR-IGMP-MIB::usrIgmpCacheVersion1HostTimer

OID (numeric): 1.3.6.1.4.1.429.4.53.2.1.8

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The time remaining until the local router 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 router ignores any IGMPv2 Leave messages for this group that it receives on this interface.

What is usrIgmpCacheVersion1HostTimer?

This read-only value (seconds) counts down the time remaining until the local router assumes there are no more IGMPv1 members of this group on the interface; it resets on any IGMPv1 report, and while nonzero the router ignores IGMPv2 Leave messages for this group on this interface. A long-running nonzero value here explains why a group isn't pruning promptly on an IGMPv2 Leave -- a legacy IGMPv1 host is still active in the group.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.53.2.1.8
snmpwalk -v2c -c public <target> USR-IGMP-MIB::usrIgmpCacheVersion1HostTimer

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.53.2.1.8.1
snmpget -v2c -c public <target> USR-IGMP-MIB::usrIgmpCacheVersion1HostTimer.1
