show spanning-tree vlan vlan-id
Step 7

Note The show spanning-tree interface interface-id privileged EXEC command displays information only
for ports that are in a link-up operative state. Otherwise, you can use the show running-config privileged
EXEC command to confirm the configuration.
To return the interface to its default setting, use the no spanning-tree [vlan vlan-id] cost interface
configuration command. For information on how to configure load sharing on trunk ports by using
spanning-tree path costs, see the
78-14982-01
Purpose
Configure the cost for an interface that is an access port.
If a loop occurs, spanning tree uses the path cost when selecting
an interface to place into the forwarding state. A lower path cost
represents higher-speed transmission.
For cost, the range is 1 to 200000000; the default value is derived
from the media speed of the interface.
Configure the VLAN cost for an interface that is a trunk port.
If a loop occurs, spanning tree uses the path cost when selecting
an interface to place into the forwarding state. A lower path cost
represents higher-speed transmission.
• For vlan-id, the range is 1 to 4094 when the EI is installed and
1 to 1005 when the SI is installed. Do not enter leading zeros.
• For cost, the range is 1 to 200000000; the default value is
derived from the media speed of the interface.
