MSTP/4/MSTPLOG_PROPORT_BPDU_GUARDED

MSTP/4/MSTPLOG_PROPORT_BPDU_GUARDED

Message

MSTP/4/MSTPLOG_PROPORT_BPDU_GUARDED:The MSTP process's edge port with BPDU protection enabled will be shut down, because it received a BPDU packet. (ProcessID=[ProcessID], PortID=[PortID], IfIndex=[IfIndex], PortName=[PortName])

Description

The edge port that has BPDU protection enabled received BPDUs and was shut down.

Parameters

Parameter Name Parameter Meaning
ProcessID Indicates the ID of an MSTP process.
PortID Indicates the port ID.
IfIndex Indicates the interface index.
PortName Indicates the port name.

Possible Causes

The edge port received BPDUs, and BPDU protection was enabled globally.

Procedure

  • The edge port received BPDUs, and BPDU protection was enabled globally.
    1. Check whether the interface is directly connected to a user terminal and can be specified as an edge port.

      • If the interface is directly connected to a user terminal and therefore can be specified as an edge port, go to Step 2.
      • If the interface is indirectly connected to a user terminal and therefore cannot be specified as an edge port, go to Step 3.

    2. Locate the source of the BPDUs on the interface and check whether the malicious attack exists.

      • If the malicious attack exists, go to Step 4.
      • If the malicious attack does not exist, go to Step 3.

    3. Run the undo stp edged-port command and the undo shutdown command in the interface view to delete the configuration of the edge port and restart the interface. Then, check whether the alarm is cleared. If the alarm persists, go to Step 4.
    4. Collect log information and configuration information, and then contact technical support personnel.
