swIGMPSnpFwdSrcAddr
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpFwdSrcAddr
OID (numeric): 1.3.6.1.4.1.171.12.73.2.1.1.1.2
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: This indicates the source IP Address of the IGMP snooping forwarding entry.
What is swIGMPSnpFwdSrcAddr?
This read-only IpAddress reports the source IP of a multicast stream in one row of the IGMP snooping forwarding table (used for source-specific, IGMPv3-style multicast). Admins check it when verifying that only the expected source(s) for a given multicast group are being forwarded, which matters for SSM (source-specific multicast) deployments. For example, if a stream from an unexpected source IP shows up here, that's a sign a rogue or misconfigured multicast source is on the segment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.2.1.1.1.2 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpFwdSrcAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.2.1.1.1.2.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpFwdSrcAddr.1
