SPANNING TREE COMMANDS

bridge-group path-cost

Use this command to configure the spanning tree path cost for the specified interface. Use the no form to restore the default.

Syntax

bridge-group bridge-grouppath-cost cost no bridge-group bridge-grouppath-cost

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

•cost - The path cost for the port. (Range: 1-65535)

•The recommended range is -

-Ethernet: 50-600

-Fast Ethernet: 10-60

-Gigabit Ethernet: 3-10

Default Setting

•Ethernet – half duplex: 100; full duplex: 95; trunk: 90

•Fast Ethernet – half duplex: 19; full duplex: 18; trunk: 15

•Gigabit Ethernet – full duplex: 4; trunk: 3

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.

Example

Console(config)#interface ethernet 1/5

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

Console(config-if)#

3-91
