swIGMPSnpDataDrivenLearningGrpRouterPorts
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpDataDrivenLearningGrpRouterPorts
OID (numeric): 1.3.6.1.4.1.171.12.73.3.1.3.1.2
Node type: OBJECT-TYPE
Type: PortList
Access: read-only
Description: This indicates the router port list of the IGMP snooping data driven learning group table.
What is swIGMPSnpDataDrivenLearningGrpRouterPorts?
This read-only PortList shows which router/uplink ports the switch is flooding a data-driven-learned multicast group toward, since there's no IGMP join to tell it which downstream ports actually want the stream. Admins use it to confirm the switch chose the correct uplink to source the stream from when data-driven learning is in play. An unexpected router port here can explain multicast traffic showing up on an uplink that wasn't expected to carry it.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.3.1.2 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpDataDrivenLearningGrpRouterPorts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.3.1.2.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpDataDrivenLearningGrpRouterPorts.1
