I'm routinely getting spammed with emails stating all of my AP's have gone down, and then 10 minutes later are coming back online. When I look into NPM, it states all of the APs have "disappeared from WL controller". I'm at a loss of where to look. My controller hasn't rebooted, the APs have been up and connected to the controller for x amount of days/weeks/months, so I'm lead to believe there's a setting or threshold somewhere in NPM that needs to be adjusted.
Any thoughts or ideas would be greatly appreciated!
there is a section under the advanced configuration which you can manipulate disappeared access points from WLC.
go to -
http:// (your host name)/Orion/Admin/AdvancedConfiguration/Global.aspx: Global
then go to the wireless section and change it if needed.
