Locating the fault when the MSTP status of a WLAN device is abnormal

When the MSTP status of a WLAN device is abnormal, perform the following operations to locate the fault:
1. Check whether configurations on each interface of the device are correct. The configurations of interfaces in the same MST domain must be the same.
2. Run the debugging stp [ interface interface-type interface-number ] packet { all | send | receive } command to check whether each interface properly sends and receives STP packets.
3. If the fault persists, collect log, alarm, and debugging information, and contact Huawei technical personnel.
