Int-Path Cost:
Enter the value of the internal path cost. The default setting is Auto,
which means the port calculates the path cost automatically
according to the port’s link speed.
Internal path cost is the path cost of the port in IST. The port with the
lowest internal root path cost will be elected as the root port in IST.
Note: Internal path cost is a parameter configured in MSTP. You
need not configure it if the spanning tree mode is STP/RSTP.
Edge Port:
Enable or disable Edge Port. By default, it is disabled.
The edge port can transit its state from blocking to forwarding
directly. If the port is connected to an end device, like a PC, it is
recommended to set the port as an edge port.
P2P Link:
Select the P2P link status. If the two ports in the P2P link are a root
port and a designated port, they can transit their states to
forwarding directly.
Three options are supported: Auto, Open(Force) and Close(Force).
By default, it is Auto.
Auto
: The switch automatically detects if the port is connected to a
P2P link, then determines the status is Open or Close.
Open(Force)
: The port is manually identified as connected to a P2P
link.
Close(Force)
: The port is manually identified as not connected to a
P2P link
MCheck:
Select whether to do MCheck operation on the port. Unchange
means no MCheck operation.
If a port on an MSTP-enabled device is connected to a
STP/RSTP-enabled device, the port switches to the STP/RSTP
compatible mode. If the STP/RSTP-enabled device is powered off or
disconnected from the MSTP-enabled device, the port cannot
switch back to MSTP mode. In this case, you can switch the port to
MSTP mode by enabling MCheck operation.
Note: MCheck is configured in MSTP. You need not configure it if the
spanning tree mode is STP/RSTP.
Port Mode:
Display the spanning tree mode of the port.
