I know that is a best practice don't put more than 20 Access Points in the same vlan where is the management interface of the controller. But i would like to know the recommendation about other vlans.
I have serious problems when I put more than 20 APs in the same VLAN I loss conectivity with the other APs and i have to disconnect the 21th AP in order to recover communication with all the APs
I'm using WLC-4404, AP 1522 and Enterasys switches. What could be the reason of this problem?
You can have up to 60 ap's on a subnet other than the subnet the wlc is on. This is Cisco's recomendations. The reason why is the amount of broadcast generated by the ap's.
