Displaying the Current STA for Ports or Modules
The parameters shown in the following figure and table are for port or
module STA Information (Port 1-12, Port 13-24, Port 25-32).

Description
Priority
Device priority is used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STA
root device. However, if all devices have the same priority, the device
with the lowest MAC address will then become the root device.

with the lowest MAC address will then become the root device.
Hello Time
The time interval (in seconds) at which the root device transmits a
configuration message.

Max Age
The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure.

Designated Root
The priority and MAC address of the device in the spanning tree that
this switch has accepted as the root device.
this switch has accepted as the root device.
Root Cost
The path cost from the root port on this switch to the root device.
Root Port
The number of the port on this switch that is closest to the root. This
switch communicates with the root device through this port. If there is
no root port, then this switch has been accepted as the root device of
the spanning tree network.
