Bridge Port Number is the Ethernet port that will be configured.
Port Priority (0~240) : If the path cost for all ports on a switch are the same, the
port with the highest priority (lowest value) will be forwarded when looping
happens. If more than one port have the same highest priority, the port with
lowest port number will be forwarded.
Port State : It is current spanning tree operation state of the port.
Port Enable : enable/disable spanning tree function on the port.
Is edge : If this switch is at “edge” of the network tree, please select “Yes”. If
there are another switches connected, please select “No”. This parameter is
used by RSTP to increase its operation speed.
Port Path Cost (1~65535) : It is used to determine the best path between devices
if looping happens. Lower values will be forwarded and should be assigned to
ports with fast connections. Higher values will be blocked and should be
assigned to ports with slow connections. The suggestion values are
100(50~600) for 10M, 19(10~60) for 100M and 4(3~10) for 1000M connections.
Port Designated Root : This will show the root bridge ID of this segment and its
bridge priority.
Port Designated Cost : This will show the path cost between the root port and
the designated port of the root bridge.
Port Designated Bridge : This will show the switch’s bridge ID and its bridge
priority setting.
Designated Port : This will show the port number and its port priority..
Port Forward Transitions : This is the forwarding transition counter on the port.
Port Role : It is the role of the port for the STP operation. It could be Root,
Designated, Backup, or Alternated. If the port is link down, the port role will be
Nonstp.
Point To Point : This is a Point-to-Point link on the port.
