N + 1 HA - question.

[Flavio Miranda]

Hi Guys,

 The " N+1 High  Availability Deployment Guide" is pretty straightforward but it is not clear if the only one command necessary on the Secondary Controller is "config redundancy unit secondary".

  In  AP SSO High Availability , the Backup Controller will get the Configuration from the Primary and  it is done. We have a cluster.  I am wondering if it does happen the same way for N + 1 HA. 

 Another point, What happen with I have 2 Primary Controllers with differents setup in terms of WLAN and Virtual Interface ?

Hello,

 After some researches, my conclusion is that this  kind of setup requires  identical configuration between Primary and backup WLC, just like redundancy performed prior to 7.4.

 I mean, the only advantage for this kind of setup is save mony with license.
