Port Configuration
This tab offers the interface for RSTP port configuration where you can assign
parameters to each port. The rapid spanning tree protocol 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.

Scroll the list box to select a port for configuration.

Path Cost: The path cost can be managed. Enter a number in the range of 1 to
200,000,000.

Priority: Port Poriority. Give the value to decide which port should be blocked by
setting its priority. Enter a number between 0 and 240. The entered value must be
a 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 states 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 an end station is known as an edge
port that won
‘t create bridging loop in the network. To configure the port as an
edge port, set the port to
―
True
‖ state.

Admin Non Stp: Configure whether the port includes the STP mathematic
calculation. True means not to include the STP mathematic calculation. False
means the STP mathematic calculation is included.

When finished, click Apply to have the configure take effect.
