swIGMPSnpFwdGrpAddr
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpFwdGrpAddr
OID (numeric): 1.3.6.1.4.1.171.12.73.2.1.1.1.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: This indicates the group IP Address of the IGMP snooping forwarding entry.
What is swIGMPSnpFwdGrpAddr?
This read-only IpAddress is the multicast group address (e.g., 239.x.x.x) for a row in the IGMP snooping forwarding table. Admins use it together with swIGMPSnpFwdSrcAddr and swIGMPSnpFwdMemberPorts to see exactly which multicast group is being delivered to which ports. For example, cross-referencing this value against a known IPTV channel's group address confirms the switch has correctly built a forwarding entry for that channel.
Examples
Walk all instances (SNMPv2c):
