assigned to ports attached to faster media, and higher values assigned to ports with slower media.

Path cost takes precedence over port priority.

Priority — Defines the priority value of the port. The priority value influences the port choice when a bridge has two ports connected in a loop. The priority value is between 0-240. The priority value is determined in increments of 16.

If the path cost for all ports on a switch are the same, the port with the highest priority (that is, 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.
