Unexpected AP adoption by another controller (VC) in the same subnet

[gluo]

Hi,

I have a setup with a VX9000 and three 7522 APs which are adopted by the VX9000.

In the same subnet I setup two 7532 one as VC and the other as adopted AP by the VC to test stuff.

When I rebooted the VX9000, all three 7522APs got adopted by the 7532VC !

when the VX9000 was back up it re-adopted the three 7522 but things were not working well because the 7532 had a newer firmware and upgraded thet 7522 APs, resulting version missmatch when the VX9000 re-adopted them.

Is this normal? Is there any way to prevent this from happening and have two isolated controller in the same subnet?

thank you in advance.

Here is the WiNG Best Practice Doc it will give more detail.

yes, its normal

One way you can prevent this by configuring 'controller host IP-addresses' on the AP profile.

In current state ssh via cli to APs and run below commands:

en
self
controller host "The IP address, hostname or host alias of the controller"
com write
