ROAMING REAUTHENTICATION

[Eduard Trullols Ripolles]

Hello.

I have an installation with two WLC,  a WLC 2100 with 12 AP and a WLC 2504 with 3 AP in the same LAN.

When a client is registered with the WLC2100 AP and roaming  to an AP in 2505 WLC, he  need to register again.

It is possible that client will always be validated in a single WLC and not needs to re-authenticate?

Thanks.

Have you configured both WLC in same mobility group with same virtual IP address on both of them ? As long as both are in same mobility group you should get smooth roaming.

Also what AireOS version running on 2100 & 2504 ?

Hi Rasika.

The solution was to configure both WLC in the same mobility group.

Thanks for your response.

As Ras points out the mobility domain shares client information between both controllers such as authentication and dhcp. The client is a dumb device in that it doesn't know that AP1 is connected to controller 1 and AP2 is connected to controller 2, it only see SSID: Production. When the client moves to the new controller its like a brand new join .. This is why you are having this issue.
