LSPM_1. hwMplsLspThresholdExceed


LSPM/3/MPLSLSPTHRESHOLDEXCEED:OID [oid] The lsp count exceeds the threshold. (hwMplsLspProtocol=[integer], hwMplsLspCurrentCount=[integer], hwMplsLspThreshold=[integer], hwMplsLspTotalCount=[integer])

The number of LSPs exceeded the upper threshold.


Alarm ID Alarm Severity Alarm Type




Name Meaning


Indicates the MIB object ID of the alarm.


LSP protocol type


Number of the current LSPs


Upper threshold of LSPs


Upper limit of supported LDP LSPs

Impact on the System

The number of hwMplsLspProtocol LSPs has reached the upper threshold. If the number continues to increase, which exceeds the threshold, services will be affected.

Possible Causes

The number of the current hwMplsLspProtocol LSPs exceeded the upper threshold.


  1. Run the display mpls lsp command to check whether unwanted hwMplsLspProtocol LSPs exist on the device.
    • If no unwanted LSPs exist, go to Step 3.
    • If unwanted LSPs exist, go to Step 2.
  2. Run the lsp-trigger command to modify a policy used by LDP to establish LSPs to reduce unwanted LSPs. Alternatively, run the undo interface tunnel command to delete unwanted RSVP-TE tunnels, and run the undo static-lsp ingress, undo static-lsp transit, and undo static-lsp static-lsp egress commands to delete unwanted static LSPs. Then check whether the alarm is cleared.
    • If the alarm is cleared, go to Step 4.
    • If the alarm persists, go to Step 3.
  3. Collect alarm information and configuration information, and then contact technical support personnel..
  4. End.
