l
Run:
jitter-packetnum
number
The number of test packets to be sent during each test is set.
NOTE
The
probe-count
command is used to configure the number of times for the jitter test and the
jitter-
packetnum
command is used to configure the number of test packets sent during each test. In actual
configuration, the product of the number of times for the jitter test and the number of test packets must
be less than 3000.
l
Run:
interval
seconds
interval
The interval for sending jitter test packets is set.
The shorter the interval is, the sooner the test is complete. However, delays arise when the
processor sends and receives test packets. Therefore, if the interval for sending test packets
is set to a small value, a relatively greater error may occur in the statistics of the jitter test.
l
Run:
fail-percent
percent
The percentage of the failed NQA tests is set.
Step 6
Run:
start
The NQA test is started.
Select the start mode as required because the
start
command has several forms.

To perform the NQA test immediately, run the

6.20.3 Checking the Configuration
After configuring the path jitter test, you can view the test result.
Prerequisite
The configurations of the Path Jitter Test function are complete.
NOTE
NQA test results cannot be displayed automatically on the terminal. You should run the
display nqa
results
command to check the test results.
