3.7.1 STP Port
Bridge Port
This option shows the port of the bridge that connects to the root bridge.
Path Cost
This parameter is used by the STA algorithm to determine the best path between devices. Therefore,
lower values should be assigned to ports attached to faster media, and higher values assigned to
ports with slower media. (Path cost takes precedence over port priority.)
The default and recommended range is: Ethernet: 100 (50~600) Fast Ethernet: 19 (10~60) Gigabit
Ethernet: 4 (3~10). The allowed range is 0 - 65535.
Priority
Defines the priority for the use of a port in the Spanning Tree algorithm. If the path cost for all ports on
a switch are the same, the port with the highest priority (i.e., lowest value) will be configured as an
active link in the Spanning Tree. Where more than one port is assigned the highest priority, the port
with lowest numeric identifier will be enabled. The range is 0 - 255.
Setup Procedures
Step 1: Select any one of the ports, from 1 to 26, to connect to the root bridge.
Step 2: Key in the value for Path Cost.
Step 3: Set the priority level.
