Root Path Cost The path cost to the designated root bridge. Traffic from a connected device to the root bridge takes
the least-cost path to the bridge. If the value is 0, the cost is automatically calculated based on port
speed.
Root Port The port on the switch with the least-cost path to the designated root bridge in the spanning tree
topology.
Topology Change
Count The number of times the topology of the spanning tree has changed.
Time Since Last

The time that has passed since the last spanning tree topology change. This value is reset to zero
when the switch is reset.
Loop

a loop-inconsistent state if loop guard is enabled and the port stops receiving BPDUs. In this state,
the interface does not transmit frames.
Transitions Into
Loop
Inconsistent State
The number of times the port has transitioned into loop inconsistent state.
Transitions Out
