COMMAND LINE INTERFACE

spanning-tree spanning-disabled

This command disables the spanning tree algorithm for the specified interface. Use the no form to reenable the spanning tree algorithm for the specified interface.

Syntax

[no] spanning-tree spanning-disabled

Default Setting

Enabled

Command Mode

Interface Configuration (Ethernet, Port Channel)

Example

This example disables the spanning tree algorithm for port 5.

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree spanning-disabled

Console(config-if)#

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
