ctPvstStpPortForwardTransitions
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctPvstStpPortForwardTransitions
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.2.6.1.11
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times this port has transitioned from the Learning state to the Forwarding state.
What is ctPvstStpPortForwardTransitions?
This read-only Counter tallies how many times this port has transitioned from the Learning state to the Forwarding state under this VLAN's spanning tree instance. An administrator watches this counter to gauge port stability for a specific VLAN, since a rapidly incrementing count indicates the port is repeatedly cycling through STP states rather than holding a stable forwarding role. For example, if this counter for an access port climbs by several increments within a few minutes, the admin suspects a flapping link or a loop being intermittently detected on that VLAN.
