Port--Spanning Tree tab fields    

The following table describes the fields on the Port Spanning Tree tab.


Field Description
Priority
Sets the value of priority that determines which bridge is the root bridge--0 to 255. The default is 128
The port priority helps determine which bridge port becomes the designated port. In a network topology that has multiple bridge ports connected to a single segment, the port with the lowest port priority becomes the designated port for the segment.
State
Displays the port's current state: disabled, blocking, listening, learning, forwarding, or broken.
Path Cost
Sets the cost of the port path--1 to 65,535. The faster the port, the lower the cost. The default is 0.
The port path cost is used to help determine the designated port for a segment. Generally speaking, the faster the port, the lower the path cost. The range is 1 to 65535. The default is 10 for 100Mbps ports, and 1 for gigabit ports. A setting of 0 indicates that the cost will be set to the appropriate default after the link speed has been auto negotiated.
Root
Displays the unique identifier of the bridge that is recorded as the root bridge in the configuration bridge protocol data units (BPDU).
Root Cost
Displays the path cost of the designated port of the segment that is connected to the port, and is compared to the Root Path Cost field in the received bridge protocol data units (BPDU).
Bridge
Displays the bridge identifier. The port interprets this bridge as the root bridge for the port's segment.
Bridge Port
Displays the port identifier. This port is the designated bridge for the port's segment.
Learn-Forward Transitions
Displays the number of times the port has transitioned from the learning state to the forwarding state.
