4-220
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.
• When the spanning-tree pathcost method (page 4-216) is set to short, the
maximum value for path cost is 65,535.
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: 0-240, in steps of 16)
Default Setting
128
Command Mode
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
the lowest numeric identifier will be enabled.
