Slot/Port - Selects one of the physical or LAG interfaces associated with VLANs associated with the
selected MST instance.

Configurable Data

Port Priority - The priority for a particular port within the selected MST instance. The port priority is
set in multiples of 16. For example, if you set the priority to any value between 0 and 15, it will be set
to 0. If it is tried to be set to any value between 16 and (2*16-1) it will be set to 16 and so on.

Port Path Cost - Set the Path Cost to a new value for the specified port in the selected MST
instance. It takes a value in the range of 1 to 200000000.

Non-Configurable Data

Auto-calculate Port Path Cost - Displays whether the path cost is automatically calculated
(Enabled) or not (Disabled). Path cost will be calculated based on the link speed of the port if the
configured value for Port Path Cost is zero.

Port ID - The port identifier for the specified port within the selected MST instance. It is made up
from the port priority and the interface number of the port.

is made up from the port priority and the interface number of the port.
