Port Configuration
This tab (Figure 73) 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 Priority. Give the value to decide which port is to 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, select
Apply
to have the configuration take effect.
