swIGMPSnpGrpRouterPorts
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpGrpRouterPorts
OID (numeric): 1.3.6.1.4.1.171.12.73.2.1.2.1.5
Node type: OBJECT-TYPE
Type: PortList
Access: read-only
Description: This indicates the router port list of the IGMP snooping group entry. This is only used for data driven learning groups. For normal groups, this object should be 0.
What is swIGMPSnpGrpRouterPorts?
This read-only PortList records the router/uplink ports associated with a data-driven-learning group entry only; for normal (report-driven) groups this object reads 0. Admins use it to see which upstream ports the switch decided to flood a data-driven-learned multicast stream toward when there was no explicit IGMP join. Seeing an unexpected router port listed here can explain why multicast traffic is reaching an uplink that wasn't expected to carry it.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.2.1.2.1.5 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpGrpRouterPorts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.2.1.2.1.5.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpGrpRouterPorts.1
