Example 

This example disables the spanning tree algorithm for port 5.

spanning-tree cost

This command configures the spanning tree path cost for the specified 
interface. Use the 

no

 form to restore the default.

Syntax 

spanning-tree

 

cost

 

cost

no spanning-tree

 

cost

 

cost

cost

 - The path cost for the port. (Range: 1-200,000,000))

 The recommended range is:

- Ethernet: 200,000-20,000,000
- Fast Ethernet: 20,000-2,000,000
- Gigabit Ethernet: 2,000-200,000 

Default Setting 

• Ethernet – half duplex: 2,000,000; full duplex: 1,000,000; trunk: 

500,000

• Fast Ethernet – half duplex: 200,000; full duplex: 100,000; trunk: 

50,000

• Gigabit Ethernet – full duplex: 10,000; trunk: 5,000

Command Mode 

Interface Configuration (Ethernet, Port Channel)

Command Usage 

• This command is used by the Spanning Tree Algorithm to determine 

the best path between devices. Therefore, lower values should be 
assigned to ports attached to faster media, and higher values assigned 
to ports with slower media. 

• Path cost takes precedence over port priority.
