Description: Current state of the Port State Transition State Machine for this port in this spanning tree context.
What is jnxMIMstMstiPortStateTransitionSemState?
This boolean value reflects the current state of the Port State Transition State Machine for a specific port within a MSTI (Multiple Spanning Tree Instance). The state machine manages the progression of the port through listening, learning, and forwarding states. Operators monitor this to track spanning tree state transitions and diagnose any ports stuck in unexpected states.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.46.1.1.7.1.18 snmpwalk -v2c -c public <target> JUNIPER-MIMSTP-MIB::jnxMIMstMstiPortStateTransitionSemState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.46.1.1.7.1.18.1 snmpget -v2c -c public <target> JUNIPER-MIMSTP-MIB::jnxMIMstMstiPortStateTransitionSemState.1
