I am very interested in the new 7.3 feature HA.
Also I can read that it is recommended to connect the two WLCs directly.
Has anyone tried to use a L2-VLAN between them, in fact to bridge a distance between two data centres?
Thank you for your answers.
I haven't tried that but I know the HA over the wan is suppose to be supported in a future release. I also believe that you can have the HA cone extend via a switch but still in the same layer 2 subnet so maybe it's possible but don't quote me on that:)

As per my understanding direct connectivity of Redundant Port is required for HA.
