A Drop Record Exists in the UDP Jitter Test Result

A Drop Record Exists in the UDP Jitter Test Result


If the UDP jitter test result has drop records, the value of the Drop operation number field in the display nqa results command output is not 0. This fault is commonly caused by one of the following:
  • The destination IP address does not exist or the route to the network segment to which the destination IP address belongs does not exist in the routing table.
  • The source IP address is incorrect.


  1. Run the display ip routing-table command on the NQA client to check whether the unicast route along the test path exists.

    • If the route exists, run the ping command to check whether devices can successfully ping each other.
    • If the route does not exist, run the corresponding command to reconfigure the route.

  2. Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA client or run the display this command in the NQA test instance view to check whether the source IP address is configured.
