swIGMPSnpDataDrivenLearningGrpGrpAddr
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpDataDrivenLearningGrpGrpAddr
OID (numeric): 1.3.6.1.4.1.171.12.73.3.1.3.1.1
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: This indicates the group address of the IGMP snooping data driven learning group table.
What is swIGMPSnpDataDrivenLearningGrpGrpAddr?
This read-only IpAddress is the multicast group address of an entry the switch learned purely from observed traffic (data-driven learning) rather than from an explicit IGMP report. Admins scan this table to see which multicast streams the switch is forwarding based on inference alone, which matters because these entries age differently (via swIGMPSnpDataDrivenLearningGrpExpiryTime) than normal report-driven group entries. Finding an unexpected group here usually means a source is streaming multicast without any client having explicitly joined via IGMP.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.3.1.1 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpDataDrivenLearningGrpGrpAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.3.1.1.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpDataDrivenLearningGrpGrpAddr.1
