Spanning Tree Commands

Example

Console(config)#spanning-tree transmission-limit 4

Console(config)#

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 4-130)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 50

Console(config-if)#

4-131
