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.

Example

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree port-priority 0

Console(config-if)#

Related Commands
