• Port: The port ID. It cannot be changed. Aggregations mean any configured
trunk group.
• Enabled: Click on the tick-box to enable/disable the RSTP protocol for the port.
• Edge: Expect the port to be an edge port (linking to an end station) or a link to
another STP device.
• Path Cost: This parameter is used by the STP to determine the best path
between devices. Therefore, lower values should be assigned to ports attached
to faster media, and higher values assigned to ports with slower media. Set the
RSTP pathcost on the port. Number between 0–200000000. 0 means auto
generated pathcost.
