Configure the ports connected directly to terminals as edge ports and enable the BPDU

protection function as well. This not only enables these ports to transit to forwarding state
rapidly but also secures your network.
 All the links of ports in a LAG can be configured as point-to-point links..
When the link of a port is configured as a point-to-point link, the spanning tree instances owning this
port are configured as point-to-point links. If the physical link of a port is not a point-to-point link and
you forcibly configure the link as a point-to-point link, temporary loops may be incurred.

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.
Select Enable to perform MCheck operation on the port. Unchange means no
MCheck operation.
Displays the STP version of the port.
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 Managed 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 backup port of a designated port.
 Disabled: Indicates the port that is not participating in the STP.
 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 STP.
Displays the working status of the port.
Displays the LAG number which the port belongs to.
