ISIS/3/ISIS_ORIG_LSP_BUFF_SIZE_MISMATCH

Message

ISIS/3/ISIS_ORIG_LSP_BUFF_SIZE_MISMATCH: The size of the local buffer for originating IS-IS LSPs is smaller than the size of the received LSP. (isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], isisPduLspId=[isisPduLspId], isisPduOriginatingBufferSize=[isisPduOriginatingBufferSize], ifIndex=[ifIndex], IfName=[IfName])

Description

The size of received LSPs was greater than that of the local buffer for locally generated LSPs.

Parameters

Parameter Name	Parameter Meaning
isisSysInstance	ID of an IS-IS process
isisSysLevelIndex	IS-IS level
isisCircIndex	Index assigned by an IS-IS interface
isisCircIfIndex	Index of an interface
isisPduLspId	LSP ID
isisPduOriginatingBufferSize	LSP buffer size. (The default LSP buffer size of IS-IS in NE/CX mode is 1497. The default LSP buffer size of IS-IS in PTN mode is 1447.)
ifIndex	Index of an interface
IfName	Interface name

Possible Causes

The size of LSPs generated on the source device was greater than that of LSPs generated on the local device.

Procedure

1. Identify the source device where the LSP was generated based on the value of the isisPduLspId field. View the size of LSPs generated on the source device and check whether it is greater than the size of LSPs generated on the local device.

If so, go to Step 2.
If not, go to Step 3.

2. Run the lsp-length originate command in the IS-IS process on the source device to change the size of generated LSPs to be smaller than or equal to the size of the buffer for locally generated LSPs.

If so, go to Step 4.
If not, go to Step 3.

3. Collect log information and configuration information, and then contact technical support personnel.

4. End.
