MSTP/3/PACKET_ERR_COMPLIAN

Message

MSTP/3/PACKET_ERR_COMPLIAN:The port compliance protocol type of the packet received by MSTP from the port [port-name] is invalid.

The MSTP port received a BPDU with an unknown format.

Parameter Name	Parameter Meaning
[port-name]	indicates the name of a port.

The MSTP module received an invalid BPDU. This BPDU might be an attack BPDU or a BPDU with the private MSTP format of a non-Huawei device.

Use a tool to get the received invalid BPDU.
Query and record the information about the remote end, including the manufacturer, version, and configuration.
- If a Huawei device is used, run the display version and display interface commands or the display current-configuration command.
- If a non-Huawei device is used, run the related commands provided by the manufacturer to obtain information on the device.
If the packet received by MSTP was invalid and hence the STP status was wrong, loops may occur at Layer 2. You are advised to shut down the interface to prevent broadcast storms. To view STP status and check whether loops occur, run the display stp brief command. After confirming that loops are removed, run the undo shutdown command to enable the interface.
Report the statistics on error packets and contact technical support personnel for further analysis.
