rlIgmpSnoopVlanIgmpVersion
Module: CISCOSB-rlBrgMulticast-MIB
OID (symbolic): CISCOSB-rlBrgMulticast-MIB::rlIgmpSnoopVlanIgmpVersion
OID (numeric): 1.3.6.1.4.1.9.6.1.101.55.2.7.1.8
Node type: OBJECT-TYPE
Type: IgmpVersion
Access: read-only
Description: The current IGMP protocol version running on the VLAN.
What is rlIgmpSnoopVlanIgmpVersion?
This read-only field reports which IGMP protocol version, v1, v2, or v3, is currently in effect for snooping on this VLAN, which can shift based on the oldest host or router version observed. An administrator checks it to understand why certain source-specific multicast features might not be working, since IGMPv1/v2 lack the source filtering that IGMPv3 provides. For example, if rlIgmpSnoopVlanIgmpVersion shows version 2 instead of the expected 3, an admin knows a legacy host or router on the VLAN is forcing the compatibility mode down.
