Description: IGMP queries version 1 processed by CPU. The number of multicast control frames that have been processed by the CPU.
What is hm2L2McastSnoopingIgmpQueriesV1FramesProcessed?
This counter tracks the number of IGMPv1 query frames processed by the switch's CPU for multicast snooping. Admins use this to detect the presence of legacy IGMPv1 devices on the network, since a nonzero count here on a network expected to run IGMPv2/v3 signals an older querier or host. For example, an unexpected rise in this counter would prompt the admin to locate and possibly upgrade the IGMPv1 device sending those queries.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.33.1.3.1.2 snmpwalk -v2c -c public <target> HM2-L2MCAST-MIB::hm2L2McastSnoopingIgmpQueriesV1FramesProcessed
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.33.1.3.1.2.1 snmpget -v2c -c public <target> HM2-L2MCAST-MIB::hm2L2McastSnoopingIgmpQueriesV1FramesProcessed.1
