6 weeks with Cisco newest wireless controller, the Catalyst 9800

With a lot of fanfare, Cisco introduced their newest wireless controller platform, the Catalyst 9800, late last year.
They are still commited to AireOS (the software the classic WLCs run - like the 5508/5520 or the giant 8540), but every time you talk to someone from Cisco it is clear that they want the new Catalyst 9800 - based on IOS-XE - to succeed.



Just to be clear, this is not a converged access controller as the 5760, that also ran on IOS-XE - this was my first thought, but the blog posts from Dave from wifireference.com or Phil from networkphil.com were assuring that this is not the case.

No matter what flavor you like - as VM as the 9800-CL or as hardware appliance as 9800-40 and 9800-80 - Cisco has got you covered.

As my WiSM2s are ageing, get no new software and are about to run out of licenses, I gave this a shot, and ordered a pair of 9800-40s, to run in HA. Sessions and Meet-the-Engineers at Cisco Live! in Barcelona were reassuring. Our Cisco partner arranged a speedy delivery - despite pretty long waiting times at the moment - and also got me a contact directly at Cisco. This has been proven to be very valuable - someone you can direct questions to that arise all the time, little issues you run into, or defects you find. There is already a good amount of documentation online, but it is still lacking in detail.

So, I had the C9800-40s now for about 6 weeks, and learned a LOT in this time:
