RSTP/MSTP/PVRST Port Parameter Descriptions
Parameter
Description
Prio
(port)
The Port Priority parameter helps determine which bridge
port becomes the designated port. In a network topology that
has multiple bridge ports connected to a single segment, the
port with the lowest port priority becomes the designated
port for the segment.
Cost
The port Path Cost parameter is used to help determine the
designated port for a segment. Generally speaking, the faster
the port, the lower the path cost. A setting of 0 indicates that
the cost will be set to the appropriate default after the link
speed has been auto negotiated.
State
The State field shows the current state of the port. The State
field can be one of the following: Discarding (DISC),
Learning (LRN), Forwarding (FWD) or Disabled (DSB).
