Problem with Citrix on Aruba WiFi

Hi, We are experiencing issues with Citrix on WiFi network, Citrix sessions get terminated couple of times a day and clients lose access to the Citrix. this only happens when they use Wireless and works fine on wired net. we have large deployment with two Aruba 7210 controller (redundant setup) and more than 100 APs that broadcast multiple SSIDs in various locations. this issue has been seen on all locations and it is not bind to one particular building or SSID. after searching on Internet some suggested that the issue is caused by broadcast and the solutions is to drop broadcast packets on VAP config. I would like to know if anyone else experiencing the same issue and what would be the possible solutions? What would be the consequences of dropping broadcasts? does this cause any issues with other applications and in general performance on WiFi network? thank you for your help and comments!

Re: Problem with Citrix on Aruba WiFi

You can try to start a constant ping to the default gateway on any device that has an issue and see what percentage of the pings get dropped.  There are plenty reasons why pings would get dropped outside of wireless, but running a ping test is a good way to see what performance your application could be getting overall.

Re: Problem with Citrix on Aruba WiFi

Thanks for your feedback but ping is not our issue here and in fact there is no L3 connectivity issue between clients to the gateway and to the Citrix server, I have done all sorts of basic tests and didn't figure any problem. This problem happens only with Citrix connections and other applications have no issue on WiFi. Could you or any one else answer the last part of my question regarding the consequences with dropping broadcast packets on VAP configuration?

Dropping brodcasts improves performance by reducing congestion realated to overhead created by broadcast traffic.  It is possible when broadcast traffic reaches a certain threshold in your environment, Citrix traffic gets dropped because it is the most sensitive.

Also, after enabling drop BC/MC (which is Aruba best practice), please add the "citrix-acl" policy to your user-role above the allowall. This will tag citrix traffic as high priority.

We have already prioritized Citrix traffic on the controller, I'll test the performance and session reliability after dropping B/M and will share the result here. Thanks!
