SDA Latency Requirements

[fatalXerror]

Hi Guys,

I know that in the SDA, the latency of each SDA components is very tight.

When designing an SDA, how can we know if we can meet the RTT? For example, from my Edge switch to my DNAC or AP to my WLC and WLC to my DNAC, how do we know if RTT is ok?

Thank you

Look at the CVD  and Datasheet -  which guide to each component RTT requirement :

Good Live Presentation also for same reference :

Thanks @balaji.bandi , thank you for the feedback. What I mean is how can we test the RTT for us to determine if RTT is ok enough for us to propose SDA?

May be you can use ping command to check the RTT reachability.

Cisco suggest best RTT to perform solution as expected, i would suggest to follow the same.

RTT only concerned if you are deploying the solution in Geo Location - Inside Campus most should be ok.

when i said Geo location, DNAC and ISE in different Location or WLC in remote Location where B/W is limitation kind of setup

In the CAMPUS LAN should be good.
