There arent almost no clients that got 802.11ac 4x4... so i can tell you they will have a nice Cisco AP 3700 ac 4x4 doing nothing in there... they wont be able to use it...
Remenber that you also need clients ac 4x4 so it can work at those speeds. If you dont have them, then you are paying for something you are not using.
Client does not know this, you have to tell him about this!
IS the cisco shop quoting them IPS/IDS?
Remenber aruba got build in IPS/IDS, stateful firewall and Cisco does not have anything of that! they have to quote them separately!
You can take that in advantage thatt your controller can do that alone...
The cisco 5760 Support for up to 1000 access points and 12,000 clients per controller
If you compare a aruba 7220 support up to 1024 APS and 24 576 clients( a way more than what cisco box can suppport)
If it a big campus fo r example a university and yo know they got more than 6000 users then you can tell them that each users brings up to 2 or 3 devices and the 7200 can keep up witht that...
Peoeple just look at the number of APS but they never look at the number of devices that are able to connect to it.
7200 is a better hardware for sure.
Also you should ask your SE for help! isnt he helping you?
