Figure 7-6 Port Config
The following entries are displayed on this screen:
Port Config
Port Select: Click the Select button to quick-select the corresponding port based
on the port number you entered.
Select: Select the desired port for STP configuration. It is multi-optional.
Port: Displays the port number of the switch.
Status: Select Enable /Disable STP function for the desired port.
Priority: Enter a value from 0 to 240 divisible by 16. Port priority is an important
criterion on determining if the port connected to this port will be chosen
as the root port. The lower value has the higher priority.
ExtPath Cost: ExtPath Cost is used to choose the path and calculate the path costs
of ports in different MST regions. It is an important criterion on
determining the root port. The lower value has the higher priority.
IntPath Cost: IntPath Cost is used to choose the path and calculate the path costs of
ports in an MST region. It is an important criterion on determining the
root port. The lower value has the higher priority.
Edge Port: Select Enable/Disable Edge Port. The edge port can transit its state
from blocking to forwarding rapidly without waiting for forward delay.
P2P Link: Select the P2P link status. If the two ports in the P2P link are root port
or designated port, they can transit their states to forwarding rapidly to
reduce the unnecessary forward delay.
MCheck: Select Enable to perform MCheck operation on the port. Unchange
means no MCheck operation.
STP Version: Displays the STP version of the port.
Port Role: Displays the role of the port played in the STP Instance.
Root Port: Indicates the port that has the lowest path cost from
this bridge to the Root Bridge and forwards packets to the root.
