Module: RAPID-CITY
OID (symbolic): RAPID-CITY::rcStgPortForwardTransitions
OID (numeric): 1.3.6.1.4.1.2272.1.13.5.1.12
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times this port has transitioned from the Learning state to the Forwarding state.
What is rcStgPortForwardTransitions?
This counter increments each time a switch port transitions from the Learning state to the Forwarding state in spanning tree. This happens after the port learns MAC addresses and is confirmed to be loop-free. Network operators use this to monitor spanning tree stability and detect excessive topology changes that might indicate flapping links or network instability.
