SPANNING TREE COMMANDS

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.

Example

Console(config)#interface ethernet 1/5

Console(config-if)#bridge-group 1 path-cost 50

Console(config-if)#

bridge-group priority

Use this command to configure the priority for the specified port. Use the no form to restore the default.

Syntax

bridge-group bridge-grouppriority priority no bridge-group bridge-grouppriority

bridge-group- Bridge group index (bridge 1).

priority - The priority for a port. (Range: 0-255)

Default Setting

128

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

This command defines the priority for the use of a port in the spanning-tree algorithm. If the path cost for all ports on a switch are the same, the port with the highest priority (that is, lowest value) will be configured as an active link in the spanning tree.

Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.

3-89
