ISIS-STD_1.3.6.1.2.1.138.0.15 isisOrigLSPBuffSizeMismatch

Description

ISIS-STD/3/LSPMTU_MISMATCH:OID [oid] The size of the local buffer for originating IS-IS LSPs is smaller than the size of the received LSP. (NotificationSysLevelIndex=[integer], CircIfIndex=[integer], PduLspId=[opaque], PduOriginatingBufferSize=[integer], PduBufferSize=[integer])

The size of a received LSP was greater than that of the local buffer where LSPs were generated.

Impact on the System

Routes cannot be learned, and traffic forwarding is affected.

Possible Causes

The size of LSPs generated on the source wireless access controller was greater than that of LSPs generated on the local wireless access controller.

Procedure

  1. Identify the source wireless access controller that generates the LSP based on the lsp-id field value in the trap. Check whether the size of the LSP generated by the source wireless access controller is greater than the size of the LSP generated by the local wireless access controller.

    • If the size of the LSP generated by the source wireless access controller is greater than the size of the LSP generated by the local wireless access controller, go to Step 2.

    • If the size of the LSP generated by the source wireless access controller is not greater than the size of the LSP generated by the local wireless access controller, go to Step 3.

  2. Run the lsp-length originate command in the IS-IS process on the source wireless access controller to change the size of generated LSPs to be equal to or smaller than the size of the buffer where LSPs are generated on the local wireless access controller. Then check whether the trap is cleared.

    • If the trap is cleared, go to Step 4.

    • If the trap is not cleared, go to Step 3.

  3. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
