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
spanning-tree port-priority
Use this command to configure the priority for the specified
interface. Use the no form to restore the default.
Syntax
spanning-tree port-priority priority
no spanning-tree port-priority
priority - The priority for a port. (Range: 0-255)
