swIGMPGroupMacAddr
Module: SW-IGMP-MIB
OID (symbolic): SW-IGMP-MIB::swIGMPGroupMacAddr
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.7.3.1.3
Node type: OBJECT-TYPE

Description: The multicast MAC address corresponds to swIGMPGroupIpAddr.
What is swIGMPGroupMacAddr?
This read-only object reports the multicast MAC address that corresponds to the IP-based multicast group address (swIGMPGroupIpAddr) in the same table row. Admins use this to see the actual Layer 2 address the switch is using to hardware-forward traffic for a given IP multicast group, useful when troubleshooting multicast forwarding at the switching-fabric level. A swIGMPGroupMacAddr of 01:00:5e:01:01:01 corresponds to the multicast MAC mapping for IP multicast group 239.1.1.1.
