WAAS 4.1 - connection statistics

Answered Question

Need help interpreting connection statistics.


The GUI shows no values against 'Percentage Compression' and 'Effective Capacity' (as per attached .jpg's)


Outputs of 'sh stat conn det' on both peer WAE's appear to show that the connection is fully optimised in both directions (as per attached .txt's).


How can I calculate optimisation result for the CLI output?


Thanks

DG

DG,


Please see the attached performance brief. I have asked for additional information on the test details (WAAS policy, Avamar configuration, etc.). I will pass those along once I have them.

DG,


The statistics show that the output bytes on the optimised connection are >= the input bytes from the original connection. So basically compression isn't buying you anything here.


What type of traffic is this? Is it encrypted?

Thanks Zach,


The connection is Avamar replication stream. It is not encrypted, but I think it may be sending only delta traffic. Are you familiar with this app? Any way to reduce bandwidth or time?


Thanks

DG

I got the following additional information about the test configuration:


"We are using TFO only. We found Avamar software use proprietary encryption which cannot be turned off."
