[Configuration and Deployment Instructions] The NQA Probe Period Is Too Short

Latest reply: Feb 23, 2019 03:11:22 1432 3 1 0 2


The NQA Probe Period Is Too Short

The probe period configured for an NQA test instance is too short. Consequently, when a probe is still going on, the next probe begins, leading to a "no result" error. As a result, association between NQA and another protocol fails.


An NQA test instance is configured.

Configuration Requirements

  1. The stop command is run in the NQA view to stop the test.

  2. The frequency interval command is run in the NQA view to configure an NQA probe period. The following inequality must be met:

    Frequency > (Probe-count – 1) x Interval + Timeout

  3. The start now command is run in the NQA view to start the test.

Misconfiguration Risks

Risk description:

If the preceding inequality is not met, a "no result" error is reported, and the board on which the NQA test instance is configured restarts. If another protocol, such as a routing protocol or VRRP, is associated with NQA, the association fails, adversely affecting service forwarding.

Identification method:

Run the display current-configuration configuration nqa command in the user view to check whether the preceding inequality is met.

In the following example, FrequencyProbe-countInterval, and Timeout are 20s, 5, 6s, and 4s, respectively. The preceding inequality is not met, and a "no result" error will be reported.

<HUAWEI> display current-configuration configuration nqa#
nqa test-instance 1 1
 test-type icmp
 destination-address ipv4 frequency 20
 interval seconds 6
 timeout 4
 probe-count 5
 start now

Recovery measures:

Ensure that the preceding inequality is met.
