Configuring a Trace Test Instance

Configuring a Trace Test Instance

Context

Before configuring a trace test instance, configure reachable routes between the NQA client and the tested device.

The NQA trace test provides equivalent functions as the tracert command but displays more detailed information.

NOTE:

Perform the following steps on the NQA client.

The timeout, probe-count, and frequency commands constrain each other; therefore, properly set the values when running the three 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 frequency value must be larger than the product of timeout and probe-count.

Procedure

  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 NQA view is displayed.

  3. Run test-type trace

    The test type is set to trace.

  4. Run destination-address { ipv4 ipv4-address | ipv6 ipv6-address }

    The destination address for the trace instance test is configured.

  5. (Optional) Run the following commands as required to configure parameters for the trace test instance.

    • Run description string

      A description is configured for the test instance.

    • Run frequency interval

      The test period is set.

    • Run timeout time

      The timeout period of a probe is set.

    • Run destination-port port-number

      The destination port number is configured.

    • Run source-address { ipv4 ipv4-address | ipv6 ipv6-address }

      The source IP address is configured.

    • Run tracert-livetime first-ttl first-ttl max-ttl max-ttl

      The initial and the maximum TTL of the packet are configured.

    • Run tracert-hopfailtimes times

      The hop fail times are set.

    • Run set-df

      Packet fragmentation is prohibited.

    • Run datasize size

      The packet size is set.

    • Run datafill fillstring

      The padding field is configured.

    • Run sendpacket passroute

      The NQA test instance is configured to send packets without searching the routing table.

    • Run probe-count number

      The number of probes in a test is set.

    • Run vpn-instance vpn-instance-name

      The VPN instance name is configured.

    • 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.
