Spanning-Tree Interface and Spanning-Tree Port Priority Example
The following example shows the VLAN port priority of an interface being configured:
Router# configure terminal
Router(config)# interface fastethernet 5/8
Router(config-if)# spanning-tree vlan 200 port-priority 64
Router(config-if)# end
Router#
The following example shows how to verify the configuration of VLAN 200 on the interface when it is
configured as a trunk port:
Router# show spanning-tree vlan 200
!
!
!
Port 264 (FastEthernet5/8) of VLAN200 is forwarding
Port path cost 19, Port priority 64, Port Identifier 129.8.
Designated root has priority 32768, address 0010.0d40.34c7
Designated bridge has priority 32768, address 0010.0d40.34c7
Designated port id is 128.1, designated path cost 0
Timers: message age 2, forward delay 0, hold 0
Number of transitions to forwarding state: 1
BPDU: sent 0, received 13513

Spanning-Tree Port Cost Example
The following example shows how to change the spanning-tree port cost of a Fast Ethernet interface:
Router# configure terminal
Router(config)# interface fastethernet 5/8
Router(config-if)# spanning-tree cost 18
Router(config-if)# end
