Description: The port's current state as defined by application of the Spanning Tree Protocol. This state controls what action a port takes on reception of a frame. If the bridge has detected a port that is malfunctioning it will place that port into the broken(6) state. For ports which are disabled (see switchBridgeStpPortEnable), this object will have a value of disabled(1).

What is switchBridgeStpPortState?

This port's current Spanning Tree state - disabled(1), blocking(2), listening(3), learning(4), forwarding(5), or broken(6) if the bridge has detected it malfunctioning - the field to check to see whether a port is actually passing traffic or held back by STP.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.207.8.9.2.2.5.2.15.1.3
snmpwalk -v2c -c public <target> SWITCH-BRIDGE-MIB::switchBridgeStpPortState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.207.8.9.2.2.5.2.15.1.3.1
snmpget -v2c -c public <target> SWITCH-BRIDGE-MIB::switchBridgeStpPortState.1
