STP-compatible mode. In this case, you can perform an mCheck operation to force the
port to migrate to the MSTP (or RSTP) mode.
You can perform mCheck on a port through two approaches, which lead to the same
result.

1.5.1 Configuration Prerequisites

MSTP has been correctly configured on the device.

1.5.2 Configuration Procedure

I. Performing mCheckglobally
Follow these steps to perform global mCheck:
Enter system view
Perform mCheck
II. Performing mCheck in Ethernet interface view
Follow these steps to perform mCheck in Ethernet interface view:
Enter system view
Enter Ethernet interface view
Perform mCheck
Caution:
The stp mcheck command is meaningful only when the device works in the MSTP (or
RSTP) mode, not in the STP-compatible mode.
