Command Usage
• This command defines the priority for the use of an interface in the
Spanning Tree Protocol. If the path cost for all interfaces on a switch
are the same, the interface with the highest priority (that is, lowest
value) will be configured as an active link in the Spanning Tree.
• Where more than one interface is assigned the highest priority, the
interface with lowest numeric identifier will be enabled.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree cost 50
Console(config-if)#
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree port-priority 0
Console(config-if)#
