Click [Configuration STA Port]. You can configure RSTP/STP on ports.
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
high speed connections. Higher values will be blocked and should be assigned to ports
with low speed 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 shows the root bridge ID of this segment and its bridge
priority.
Port Designated Cost : This shows the path cost between the root port and the
designated port of the root bridge.
Port Designated Bridge : This shows the switch’s bridge ID and its bridge priority setting.
Designated Port : This shows 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.
