What is rcVlanIgmpSnoopNumGroups?

This object reports the total number of IGMP multicast group entries currently tracked in an IGMP snooping table for a specific VLAN. Network operators monitor this counter to understand the volume of active multicast groups on the VLAN and detect unexpected growth in multicast group membership. High values may indicate network misconfigurations or excessive multicast traffic.
