To change the bridge priority of VLAN pink to 69, type the following command:

WX1200# set spantree priority 69 vlan pink success: change accepted.

Changing STP Port You can change the STP cost and priority of an individual port, on a Parameters global basis or an individual VLAN basis.

Changing the STP Port Cost

To change the cost of a port, use one of the following commands.

set spantree portcost port-listcost cost

set spantree portvlancost port-listcost cost {all vlan vlan-id}

The set spantree portcost command changes the cost for ports in the default VLAN (VLAN 1) only. The set spantree portvlancost command changes the cost for ports in a specific other VLAN or in all VLANs.

Specify a value from 1 through 65,535 for the cost. The default depends on the port speed and link type. (See Table 29 on page 353.)

The all option applies the change to all VLANs. Alternatively, specify an individual VLAN.

To change the cost on ports 3 and 4 in the default VLAN to 20, type the following command:

WX1200# set spantree portcost 3,4 cost 20 success: change accepted.

To change the cost for the same ports in VLAN mauve, type the following command:

WX1200# set spantree portvlancost 3,4 cost 20 vlan mauve success: change accepted.

Resetting the STP Port Cost to the Default Value

To reset the STP port cost to the default value, use one of the following commands:

clear spantree portcost port-list

clear spantree portvlancost port-list{all vlan vlan-id}
