igmpInterfaceGroups
Module: IGMP-STD-MIB
OID (symbolic): IGMP-STD-MIB::igmpInterfaceGroups
OID (numeric): 1.3.6.1.2.1.85.1.1.1.13
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The current number of entries for this interface in the Cache Table.
What is igmpInterfaceGroups?
A read-only gauge reporting the current number of multicast group memberships, or cache entries, associated with this interface. This gives an admin a quick count of how many distinct multicast groups currently have active members on this interface's segment, useful for spotting unexpectedly high multicast group counts. A router interface reporting igmpInterfaceGroups of 15 has 15 distinct multicast groups currently being tracked with active members on that segment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.85.1.1.1.13 snmpwalk -v2c -c public <target> IGMP-STD-MIB::igmpInterfaceGroups
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.85.1.1.1.13.1 snmpget -v2c -c public <target> IGMP-STD-MIB::igmpInterfaceGroups.1
