Just brainstorming here... CAPWAP tried to accomplish some standardization for Controller/AP communication, but I haven't seen many CAPWAP compatible devices! http://en.wikipedia.org/wiki/CAPWAP
This said, if you follow what's happening with OpenFlow (http://en.wikipedia.org/wiki/OpenFlow) on switches, and since switches and wireless equipment seem to progressively integrate, we could make a leap and think that eventually there will be a common set of features that will be standardized for wireless as well. OpenFlow accomplishes on switches what we have been doing with wireless for a few years: Separation of control plane and data plane! This reminds me a little bit of OBD-II with cars. Part of the settings are public and standard, part of it is private!

For multi-vendor wireless monitoring & management, the Airwave AWMS (AMP) product has excelled for many years. Even though the product is now owned by Aruba Networks, Airwave has retained its multi-vendor features.

I know this is probably unlikely to happen, but we have interoperable wired networks and I just wish the same for the wireless side. Maybe a universal controller is more realistic, something that understands how to talk to all types of APs. -- Daniel Eklund Network Planning Manager ITS Communications Systems and Data Centers University of Michigan 734.763.6389 On Tue, Jan 29, 2013 at 1:34 PM, Peter P Morrissey <[email protected]<mailto:[email protected]>> wrote: My view regarding the 3850 is that anything that locks you into a vendor, and makes it more difficult to switch to a competitor is a bad thing for the consumer, and should be considered with your eyes wide open to the long term consequences. In my mind, one would have to make an extremely compelling business case to counter that tradeoff. Keep in mind that the Vendor’s job is to make “switching costs” as high as possible for the consumer. It is bad enough that we still have to purchase AP’s and controller’s from the same vendor. The 5700 looks like a great idea for those of us with large wireless networks.

The datasheet for the Cat3850 has some info on this new option. Could be situationally useful, but I'm not quite sold on the advantages vs. the current model for higher ed where many of us are using big central pools of real IPs and no NAT for our wireless users.
