swIGMPSnpDynamicRouterPorts
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpDynamicRouterPorts
OID (numeric): 1.3.6.1.4.1.171.12.73.3.1.4.1.10
Node type: OBJECT-TYPE
Type: PortList
Access: read-only
Description: This indicates the dynamic router port list of the IGMP snooping router ports table.
What is swIGMPSnpDynamicRouterPorts?
This read-only PortList shows which ports the switch has automatically detected as multicast router/uplink ports, typically by observing IGMP queries or multicast routing protocol hellos arriving on them. Admins check it to confirm the switch is correctly identifying the real router-facing ports; multicast traffic and reports get flooded to these ports even without an explicit join. If an expected uplink is missing here, static configuration via swIGMPSnpStaticRouterPorts may be needed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.4.1.10 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpDynamicRouterPorts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.4.1.10.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpDynamicRouterPorts.1
