Chapter 6. Manage / Configure the Switch

addition, each port needs time to listen for conflicting information that would make it return to a blocking state;
otherwise, temporary data loops might result.
The parameters have relation with each other. And here is the rule for it.
2*(Hello Time +1) is less or equal to
Maximum Age, and Maximum Age is less or equal to 2*(Forward Delay -1).
[Setting of Port]
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.
