spanning-tree cost

The

spanning-tree cost

Interface Configuration mode command configures the spanning tree path cost for a

port. To return to the default configuration, use the

form of this command.

Syntax

spanning-tree cost cost

no spanning-tree cost

Parameters
•

cost

— Path cost of the port (Range: 1 - 200,000,000)

Default Configuration

Default path cost is determined by port speed and path cost method (long or short) as shown below:

Command Modes

Interface Configuration (Ethernet, port-channel) mode

User Guidelines

The path cost method is configured using the

spanning-tree pathcost method

Global Configuration mode com-

mand.

Example

The following example configures the spanning-tree cost on Ethernet port 5 to 35000.
