    I noticed today that one of our 3400 master controller is showing alot of APs as being down.  I checked Airwave and it shows them as up.  I am able to ping the APs even from the controller.

     

    Why is the controller showing them as being down?

    -What version of code is this?

    - Is that controller a master or a local controller?

    - Do you see the APs as down on the commandline, GUI or both?

    - type "show ap bss-table" to see if those access points are even broadcasting.

    i've seen similar behaviour on a 3200 running 6.1.2.3 and it turned out that the DHCP server had exhausted the scope and the AP's were dropping off the controller and rebooting.

     

    I think there was some double allocation going on that was causing the erratic behaviour.

    *Version is 3.4.1.0

    *It's a Master

    *See them down on the CLI and GUI

    *APs that are down are not broadcasting, ones that are up are.
