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.
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

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