configuration message (BPDU frame). Number between 1-10 (default is 2). ¾ Max Age - The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. That also means the maximum life time for a BPDU frame. Number between 6-40 (default is 20). ¾ Forward Delay: The maximum time (in seconds) the root device will wait before changing states (i.e., discarding to learning to forwarding). Number between 4 - 30 (default is 15). ¾ Force Version: Set and show the RSTP protocol to use. Normal - use RSTP, Compatible - compatible with STP. Figure 1-8-1 RSTP Port Configuration ¾ Port: The port ID. It cannot be changed. Aggregations mean any configured trunk group. ¾ Enabled: Click on the tick-box to enable/disable the RSTP protocol for the port. ¾ Edge: Expect the port to be an edge port (linking to an end station) or a link to another STP device. ¾ 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. 17
