After upgrading my controller to SW 7.4.121.0 and FUS I 7.0.112.21, most of my AP's are not getting connected to the controller. I had 300 AP before the upgrade but after upgrading only 90 AP are connected. Any help.

The issue is resolved by

The issue is resolved by rebooting  the POE switches, somehow few POE switches had stopped broadcasting the mac adddress of the AP infra vlans due to which the mac was not reaching to the core switch. Once we rebooted those switches the mac started broadcasting on core and then it worked.

 

The switch model number is WS-C3560X-24P. Could there be any bug on the switch? This is the IOS we are using in switch

Not sure but I sure wouldn't

Not sure but I sure wouldn't stay at that IOS level.  SE9 packs more fixes than SE3.  

 

However, if the issue was resolved by rebooting the switch, it's a sure sign to upgrade the IOS.
