the switch priority is 32768.
Description
Using stp priority command, you can configure the bridge priority in the specified STI.
Using undo stp priority command, you can restore the default value of bridge priority .

instance-id: Specifies the spanning tree instance ID, ranging from 0 to 16, instance 0 is
CIST.
port priority priority: Specifies the port priority, ranging from 0 to 240, with a step length
of 16, e.g., 0, 16, and 32. By default, the priorities of a port on the STIs are 128.
Description
Using stp port priority command, you can configure the priority of a port on a specified
STI. Using undo stp port priority command, you can restore the default priority of the
port on the specified STI.
You may specify the instance-id parameter as 0 to configure CIST priority of the port.
The port priority has effect on the port role selection. A port can be configured with
different priorities on different MSTIs. Thus the traffic from different VLANs can run over
different physical links, thereby implementing the VLAN-based load-balancing. MSTP
will recalculate the port role and transit its state, upon the port priority changes.
