This example shows how to configure the port priority at an individual port VLAN cost for VLAN 200:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface fastEthernet 4/4
Router(config-if)# spanning-tree vlan 200 cost 2000
Router(config-if)# ^Z
Router#
This example shows how to verify the configuration:
Router# show spanning-tree vlan 200 interface fastEthernet 4/4
Interface
---------------- ---- --- --------- -------- --------------------------------
Fa4/4
In the following output other VLANs (VLAN 1 for example) have not been affected by this
Note
configuration.
Router# show spanning-tree vlan 1 interface fastEthernet 4/4
Interface
---------------- ---- --- --------- -------- --------------------------------
Fa4/4
Router#
Note The show spanning-tree command only displays information for ports that are in link-up operative state
and are appropriately configured for DTP. If these conditions are not met, you can enter a show
running-config command to confirm the configuration.

Configuring the Bridge Priority of a VLAN

Be careful when using this command. For most situations, we recommend that you enter the
Note
spanning-tree vlan vlan_ID root primary and the spanning-tree vlan vlan_ID root secondary
commands to modify the bridge priority.
