igmpSnoopVLANLeaves
Module: A3COM0073IGMP-SNOOP
OID (symbolic): A3COM0073IGMP-SNOOP::igmpSnoopVLANLeaves
OID (numeric): 1.3.6.1.4.1.43.10.37.1.9.1.2
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times a group membership has been removed from this VLAN; i.e. the number of times an entry for this VLAN has been deleted from the IGMP Snooping VLAN Table. The difference between this and igmpSnoopVLANJoins indicates the number of hosts listening to multicasts. The count of IGMP Leaves received over time on a VLAN.
What is igmpSnoopVLANLeaves?
This counter tracks how many times multicast group memberships have been removed from the VLAN, representing IGMP Leave messages received. Engineers compare leaves against joins to estimate active multicast listeners: if joins exceed leaves significantly, many clients are subscribed. A balanced join-to-leave ratio indicates stable multicast group membership.
