I am currently looking at the Cisco 3850 Catalyst+WLC. I saw that they could be stacked, but you can only have 50 APs registered.
What happens if you link 2 3850 using HSRP ? I suppose you'll be able to register up to 100 APs, but when you want to authenticate your 3850s on an CS, will you be able to register only the "virtual IP" of both devices ? I mean, can you authenticate the 2 devices as one device on the ACS ? (I hope I was able to explain my problem !)
