RSTP System Configuration interface

6.19.2 Port Configuration

This web page provides the port configuration interface for RSTP. You can assign higher or lower priority to each port. Rapid spanning tree will have the port with the higher priority in forwarding state and block other ports to make certain that there is no loop in the LAN.

•Select the port in the port column field.

•Path Cost: The cost of the path to the other bridge from this transmitting bridge at the specified port. Enter a number 1 through 200,000,000.

•Priority: Decide which port should be blocked by setting its priority as the lowest. Enter a number between 0 and 240.The value of priority must be the multiple of 16.

•Admin P2P:The rapid state transitions possible within RSTP are dependent upon whether the port concerned can only be connected to exactly another bridge (i.e. it is served by a point-to-point LAN segment), or can be connected to two or more bridges (i.e. it is served by a shared medium LAN segment). This function allows the P2P status of the link to be manipulated administratively.True means the port is regarded as a point-to-point link. False means the port is regarded as a shared link.Auto means the link type is determined by the auto-negotiation between the two peers.

•Admin Edge:The port directly connected to end stations won’t create bridging loop in the network.To configure the port as an edge port, set the port to “True” status.

•Admin Non Stp:The port includes the STP mathematic calculation.True is not including STP mathematic calculation. False is including the STP mathematic calculation.
