Displaying the STP Port Cost on a VLAN Basis

In this example, VLAN mauve contains ports 1 through 3, 5 and 6. Ports 1 and 5 are forwarding traffic. The other ports are blocking traffic.

(For more information about the fields in the output, see the Wireless LAN Switch and Controller Command Reference.)

To display a brief list of the STP port cost for a port in each of its VLANs, use the following command:

display spantree portvlancost port-list

This command displays the same information as the display spantree command’s Cost field in a concise format for all VLANs. The display spantree command lists all the STP information separately for each VLAN.

To display the STP port cost of port 1, type the following command:

WX1200# display spantree portvlancost 1 port 1 VLAN 1 have path cost 19
