spanning-tree priority (port priority)
Overview
Use this command in Interface Configuration mode for a switch port interface only
to set the port priority for port. A lower priority value indicates a greater likelihood
of the port becoming part of the active topology.
Use this command for RSTP, STP, or MSTP. When the device is in MSTP mode, this
will apply to the CIST.
Use the
no
variant of this command to reset it to the default.
Syntax
spanning-tree priority <

>
no spanning-tree priority
Default
The default priority is 128.
Mode
Interface Configuration mode for a switch port interface only.
Usage
To force a port to be part of the active topology (for instance, become the root port
or a designated port) use a lower value than other ports on the device. (This
behavior is subject to network topology, and more significant factors, such as
bridge ID.)
