Costs of all the switches that the packet goes through.
The Root Path Cost of the Root Bridge is zero.
♦ Bridge Priority This is a parameter that users can set.
The smaller the number you set, the higher the Bridge
Priority is. The higher the Bridge Priority, the better the
chance the Switch will be selected as the Root Bridge.
On the Port Level
♦ Root Port Each switch has a Root Port. This is the port
that has the lowest Path Cost to the Root Bridge. In case
there are several such ports, then the one with the lowest
Port Identifier is the Root Port.
♦ Designated Port This is the port on each Designated
Bridge that is attached to the LAN segment for which the
switch is the Designated Bridge.
♦ Port Priority The smaller this number, the higher the
Port Priority is. With higher Port Priority, the higher the
probability that the port will be selected as the Root Port.
♦ Path Cost This is a changeable parameter and may be
modified according to STA specifications. Each 10Mbps
and 100Mbps segment has an assigned Path Cost of 19.
