Usage guidelines

When a port on an MSTP, RSTP, or PVST device connects to an STP device and receives STP BPDUs, the port automatically transits to the STP mode. However, the port cannot automatically transit back to the original mode when the following conditions exist:

• The peer STP device is shut down or removed.

• The port cannot detect the change.

In this case, you can perform an mCheck operation to forcibly transit the port to operate in the original mode.

The device operates in STP, RSTP, PVST, or MSTP mode, depending on the spanning tree mode setting.

The stp global mcheck command takes effect only when the device operates in MSTP, RSTP, or PVST mode.
