NOTE
If you run the stp mcheck command in the system view, the MCheck operation is performed on all the
interfaces.

9.4.3 Configuring Port Parameters
Port parameters that may affect MSTP topology convergence include the link type and maximum
number of sent BPDUs. Configure proper port parameters to implement rapid topology
convergence.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The Ethernet interface view is displayed.
Step 3 (Optional) Run:
stp point-to-point { auto | force-false | force-true }
The link type is configured for a port.
By default, a port automatically determines whether to connect to a P2P link. The P2P link
supports rapid network convergence.
l If the Ethernet port works in full-duplex mode, the port is connected to a P2P link. In this
case, force-true can be configured to implement rapid network convergence.
l If the Ethernet port works in half-duplex mode, you can configure stp point-to-point force-
true to forcibly set the link type to P2P to implement rapid network convergence.
Step 4 Run:
stp mcheck
MCheck is enabled.
On a switching device running MSTP, if an interface is connected to a device running STP, the
interface automatically transitions to the STP mode.
Enabling MCheck on the interface is required because the interface may fail to automatically
transition to the MSTP mode in the following situations:
l The switching device running STP is shut down or moved.
l The switching device running STP transitions to the MSTP mode.
Step 5 Run:
stp transmit-limit packet-number
The maximum number of BPDUs sent by a port within each Hello time is set.
By default, the maximum number of BPDUs that a port sends within each Hello time is 147.
