Hi Sai Prasad,
general rule of thumb is always use active / standby setup. Certain services like Captive Portal etc. relies on a single adopter etc.
I am just looking into older release notes and here is the statement:
"Only two (2) controllers in a cluster are supported in WiNG 5.2 and higher, the same as in WiNG v5.1.x. Cluster creation changed in WiNG v5.2 as compared to WiNG v5.1.x."Please disregard my previous sentence:
"Running code below 5.2 allows only two cluster members in active / standby mode."Only after version 5.6 system allows to use up to 6 members for RFS platforms
