MSTP/4/MSTPLOG_PROEDGE_PORT_CHANGED

Message

MSTP/4/MSTPLOG_PROEDGE_PORT_CHANGED: After the edge port receives a BPDU packet, the port is no longer an edge port. (ProcessID=[ProcessID], PortID=[PortID], IfIndex=[IfIndex], PortName=[PortName], PwName=[PwName], SrcMac=[SrcMac], TAG=[VlanId], RootMac=[RootMac], RootPri=[RootPri], DesignMac=[DesignMac], DesignPri=[DesignPri], RegionRootMac=[RegionRootMac], RegionRootPri=[RegionRootPri], RcvsendPortId=[RcvsendPortId], RcvsendPorPri=[RcvsendPorPri])

Description

The edge port lost the edge port attribute after receiving BPDUs.

Parameters

Parameter Name	Parameter Meaning
ProcessID	MSTP instance ID.
PortID	Port ID.
IfIndex	Port index.
PortName	Port name.
PwName	PW name.
SrcMac	Source MAC address.
VlanId	VLAN ID.
RootMac	MAC address of the root bridge.
RootPri	Root bridge priority.
DesignMac	MAC address of the designated bridge.
DesignPri	Designated bridge priority.
RegionRootMac	MAC address of the region root bridge.
RegionRootPri	Priority of the region root bridge.
RcvsendPortId	Sending port number in the received packet.
RcvsendPorPri	Priority of the transmit port in the received packet.

Possible Causes

The edge port received BPDUs.

Procedure

1. Check whether the port should be planned as an edge port.

If the port should be planned as an edge port, go to Step 2.
If the port should not be planned as an edge port, go to Step 3.

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

If a malicious attack exists, go to Step 4.
If no malicious attack exists, go to Step 3.

3. Run the undo stp edged-port command and the undo shutdown command in the interface view to delete the edge port configuration 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.
