Haven't seen anything like those over the last 8 or so years.
Mixture of APs from 1131s all the way up to 3702s, and 2504, 5508
and 8510 controllers.

We don't use prime/wcs/ncs/whatever Cisco are promoting these
days, and use an in-house system instead for basic AP management
and monitoring.

Re: [WIRELESS-LAN] Sanity check- spontaneously changing WLC configs- is it just us?

[Jeffrey D. Sessler]

Nothing at like that here. We had some growing pains back in the Cisco 5.0.x 
days, but have otherwise been OK since… small little bugs here and there, but 
nothing I wouldn’t expect from such complex code i.e. The campus here with 
Aruba runs into the same little stuff all the time.

Perhaps you’ve carried a lot of old configuration crud forward over the years 
that the various upgrades didn’t clean up?

Have you ever used the Cisco WLC config analyzer? It’s really helpful in 
finding odd crud and/or offering suggestions to problems you may not even be 
aware you’re having.

Not so much looking for a solution here, but wondering if anyone else has seen 
similar. Having been on the Cisco thin thrill ride for almost a decade now, 
I’ve always been of the mind that gremlins like to make odd little config 
changes over time in the WLCs. Lately I’ve found:


  *   APs renaming themselves
  *   Clean Air getting wholesale disabled on a controller
  *   APs that way back when were config’d with static IP addresses, but that 
have been using DHCP for years, going back to showing static IPs configs
  *   APs taking themselves out of a given AP group to default


The odd thing is lack of pattern. An AP or two from a controller or a building, 
but not others from the same general grouping. Basically configs that have been 
in place for months or years and several code versions just changing on a small 
percentage of APs with no seeming rhyme or reason. Very few hands are allowed 
anywhere near the important parts of the soup, and I know it’s not a matter of 
human error.

Does anyone else experience anything like this?

[Ciesinski, Nick]

Lee,


  *   APs renaming themselves  - YES
  *   Clean Air getting wholesale disabled on a controller - NO
  *   APs that way back when were config’d with static IP addresses, but that 
have been using DHCP for years, going back to showing static IPs configs - NO
  *   APs taking themselves out of a given AP group to default - NO

Let me add one that we see not on your list.


  *   APs that had a controller preference order set remove all controllers and 
go back to the default blank setting.
