The following entries are displayed on this screen:
Port Config
UNIT:1/LAGS: Click 1 to configure the physical ports. Click LAGS to configure the
link aggregation groups.
Select: Select the desired port for STP configuration. It is multi-optional.
Port: Displays the port number of the switch.
Status: 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: Ext
Path 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: 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: Enable
to perform MCheck operation on the port. Unchange means
no MCheck operation.
Port Mode: Display the spanning tree mode 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.
Designated Port
: Indicates the port that forwards packets to a
downstream network segment or switch.
Master Port
: Indicates the port that connects a MST region to
the common root. The path from the master port to the common
root is the shortest path between this MST region and the
common root.
Alternate Port: Indicates the port that can be a backup port of a
root or master port.
Backup Port: Indicates the port that is the back
up port of a
designated port.
Disabled: Indicates the port that is not participating in the STP.
Port Status: Displays the working status of the port.
Forwarding
: In this status the port can receive/forward data,
receive/send BPDU packets as well as learn MAC address.
Learning: In this status the port can receive/send BPDU packets
and learn MAC address.
Blocking: In this status the port can only receive BPDU packets.
Disconnected
: In this status the port is not participating in the
S TP.
