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 - 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.
When the spanning-tree pathcost method (page 4-186) is set to short,
the maximum value for path cost is 65,535.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree cost 5000
Console(config-if)#
