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.
