To globally enable or disable the spanning tree feature, use the stp enable command or undo stp
enable command in system view.
• You can disable the spanning tree feature for certain ports with the undo stp enable command to

Performing mCheck
If a port on a device running MSTP, or RSTP connects to an STP device, this port will automatically
transition to the STP-compatible mode. However, it cannot automatically transition back to the original
mode when:
• The STP device is shut down or removed.
• The STP device transitions to the MSTP, or RSTP mode.
To forcibly transition the port to operate in the original mode, you can perform an mCheck operation.
The following methods for performing mCheck produce the same result.
