TP-Link TL-SG2008 Priority, ExtPath, IntPath, Edge Port, P2P Link, MCheck, STP Version, Port Role

The following entries are displayed on this screen:

¾Port 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:	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:	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.
	z Root Port: Indicates the port that has the lowest path cost from
	this bridge to the Root Bridge and forwards packets to the root.
	z Designated Port: Indicates the port that forwards packets to a
	downstream network segment or switch.
	z Master Port: Indicates the port that connects an 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.
	z Alternate Port: Indicates the port that can be a backup port of a
	root or master port.
	z Backup Port: Indicates the port that is the backup port of a
	designated port.
	z Disabled: Indicates the port that is not participating in the STP.

Port Status:

z

z

z

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.
