Performance with encrypted CAPWAP?

[Chad S]

Does anyone have experience with encrypting CAPWAP tunnels on between your AP's and WLC's?  

According to:

http://www.cisco.com/c/en/us/td/docs/wireless/controller/6-0/configuration/guide/Controller60CG/c60lwap.html#wp1508163

"Encryption limits throughput at both the controller and the access point, and maximum throughput is desired for most enterprise networks."

My question is- has anyone enabled encryption and seen if there is actually degradation in throughput?  We are considering enabling encryption on a couple hundred APs and dont want this extra overhead to bog things down on the controllers or APs.

Thanks

Hi,

no there will be no degradation in throughput after enabling encryption.

dont worry.

Thanks for your reply Sandeep.  If you dont mind me asking, do you have this running on a large number of APs in your environment?

Hi Chad,

No we dont have large number of APs in our enviournment.

But my recommandation is: Enable only  when you need like for mesh or office extends AP(to add security).

I will not recommand to enable on local mode APs.

As per cisco:

Encryption limits throughput at both the controller and the access point, and maximum throughput is desired for most enterprise networks.
