Cisco WLC 5508 Redundancy Feature

[Quoc Le]

All,

With version 7.3 there is a feature for redundancy. How does this feature work? Does anyone know? Can it be use where it is not directly connected, but can be connected as a layer 2?

There have always been redundancy. v7.3 introduced HA AP SSO... did not really start off pretty well. Even with v7.4, there are still some open issues.

Here is how redundancy has always been implemented.

Oh.. Here is HA N+1 which is stable compared to HA AP SSO.

Hi Scott,

For the moment do you preconize HA N+1 with V7.4 or AP SSO V7.3 on WLC5508 ?

I also will install Pi version 1.2 , does it support controllers 5508 in version 7.4? Refering to config guide I would say yes ..

Thanks
