Spirent TestCenter: Do we support latency values in Latency-Jitter Mode for Detailed Streams results view?
Environment/Versions
What counter mode supports Latency and Jitter counters at the same time?
v4.71
v4.81
All test modules
Latency-Jitter Mode
Latency with RFC 5481 Jitter Mode
Latency - Jitter
Answer
On the older modules like CV-10G-S and MX-10G-S we have the original Latency-Jitter Mode. For these modules we supported latency, jitter and dropped frame count in this mode.
The
new counter mode:
Latency with RFC 5481 Jitter Mode was introduced in
4.81
release that allows latency and jitter to be collected concurrently per stream
ONLY
for Spirent FX3/MX3, 400G Appliance and 400G Modules
Since the newer modules FX3/FX2 and MX3/MX2 were designed for higher stream counts. The trade-off was a smaller number of counters for each counter mode, that was the initial reason the first counter (Latency-Jitter mode) isn't showing Lattency and Jitter on the same view)
Please refer to KB:
