An LSP with a parse error was received.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.2.1.138.0.18	Major	environmentalAlarm(6)

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
NotificationSysLevelIndex	IS-IS level of a device that sends the trap
LspID	LSP ID
CircuitIfIndex	Interface index
PduFragment	64-byte PDU header
ErrorOffset	Offset of an error TLV
ErrorTLVType	Error TLV type

Impact on the System

The TLV cannot be parsed, and therefore information may be lost.

Possible Causes

An error occurred when a received LSP was parsed.

Procedure

Search the trap information for the error TLV and the offset of the error TLV for fault location.
Use a packet obtain tool to obtain packet headers sent by the remote device, check whether the fault occurs, and determine whether the local device incorrectly parses the packet or the remote device sends an incorrect packet.
- If the remote device sends an incorrect packet, go to Step 4.
- The local device incorrect parses the packet, go to Step 3.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
