What is snIfStpPortNum?

This is the port number on the switch that participates in the spanning tree protocol for loop prevention. It matches the standard interface index and identifies which physical port is being monitored by the spanning tree algorithm. An operator checks this to verify which ports are actively forwarding or blocked in the topology.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.5.2.1.2
snmpwalk -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snIfStpPortNum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.5.2.1.2.1
snmpget -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snIfStpPortNum.1
