Configuring the LSP Ping Test

Configuring the LSP Ping Test


The NQA LSP Ping test can be used to test the reachability of the LSP tunnel.


Perform the following steps on the NQA client.

The timeout, probe-count, frequency, and interval commands constrain each other; therefore, properly set the values when running the four commands. Improper command settings may lead to test failure.

  • On a network with poor quality and low transmission rate, increase the timeout value to ensure that the response to NQA detection packets can be received.
  • On a network with low reliability, increase the probe-count value because multiple detection packets may need to be sent to ensure successful detection.
  • The interval value must be larger than the timeout value.
  • The frequency value must comply with the following rules:

    frequency > interval x (probe-count - 1) + timeout


  1. Run system-view

    The system view is displayed.

  2. Run nqa test-instance admin-name test-name

    An NQA test instance is created and the test instance view is displayed.

  3. Run test-type lspping

    The test type is set to LSP ping.

  4. Configure the LSP ping test for the LSP tunnel.

    • Run lsp-type ipv4

      The test type of the LSP Ping is configured.

    • Run destination-address ipv4 ipv4-address [ lsp-masklen masklen | lsp-loopback loopback-address ] *

      The destination IP address to be tested is configured.

  5. (Optional) Perform the following as required to configure other parameters for the LSP ping test:

    • Run lsp-nexthop nexthop-ip-address

      The next-hop IP address in the scenario where load balancing is enabled is configured on the initiator of the LSP ping test.

    • Run lsp-replymode { level-control-channel | no-reply | udp }

      The response mode of the LSP Ping test is set.


      In a uni-directional LSP Ping test, if the lsp-replymode no-reply command is configured, the test result shows that the test fails regardless of whether the test is successful or fails. If the test is successful, the test result also displays the number of the timeout packets. If the test fails, the test result displays the number of the discarded packets.

    • Run lsp-exp exp

      The LSP EXP value is set.

    • Run fragment enable

      MPLS packet fragmentation is enabled for an NQA test instance.

    • Run description string

      A description is configured for the test instance.

    • Run frequency interval

      The interval at which an NQA test instance is automatically performed is set.

    • Run timeout time

      The timeout period of a probe is set.

    • Run source-address ipv4 ipv4-address

      The source IP address is configured.

    • Run ttl number

      The TTL value is set.

    • Run datafill fillstring

      The padding field is configured.

    • Run datasize size

      The packet size is set.

    • Run probe-count number

      The number of probes in each test is set.

    • Run fail-percent percent

      The failure percentage is set.

    • Run interval seconds interval

      The interval at which test packets are sent is set.

    • Run records history number

      The maximum number of historical records is set.

    • Run records result number

      The maximum number of result records is set.

    • Run agetime hh:mm:ss

      The aging time is set for the test instance.

  6. Run commit

    The configuration is committed.
