Hello guys, I got a quesiont when testing the NQA and the ping result.

Below is sample configuration‍‍

[HQ-6720]dis cu

#

nqa test-instance 1065635Mumdc_to_Ashok_Andheri_TCL

test-type icmp

destination-address ipv4 192.168.1.5

source-address ipv4 192.168.1.6

frequency 300

probe-count 15

datasize 56

start now

#

return

‍‍‍‍We have configured NQA for some the major links. But as checked there is lot of variations in the latency for results of NQA.‍‍

Please find below Screen Shot captured.

‍‍Above showing as the latecy value to be 29 ms. But actually checked the latency by ping is much less.
