Disabled

Command Mode

Interface Configuration (Ethernet, Port Channel)

Example

Console(config)#interface ethernet ethernet 1/5

spanning-tree mst cost

This command configures the path cost on a spanning instance in the Multiple Spanning Tree. Use the no form to restore the default.

Syntax

spanning-tree mst instance_id cost cost no spanning-tree mst instance_id cost

instance_id - Instance identifier of the spanning tree. (Range: 0-4094, no leading zeroes)

cost - Path cost for an interface. (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

-10 Gigabit Ethernet: 200-20,000

Default Setting

By default, the system automatically detects the speed and duplex mode used on each port, and configures the path cost according to the values shown below. Path cost “0” is used to indicate auto-configuration mode.

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
