Getting Breaks while testing failover in unleased network.

While testing the failover of the 'Dedicated Master R750' controller, we are experiencing network interruptions, causing all devices connected to the unleashed WLAN to lose connectivity, need your seggestion on this to how to overcome this issue.

Hi Sanjay,

I have installed 2 R750 (as Dedicated Master) in two different location (MPLS). both location also have 14-14 R650 AP's. client asked me to do fail-over test of active controller (R750). but when i do the failover test or reboot the master Controller(master R750). all the the clients connected to the unleased WLAN got disconnected(Radio shuts down). user shouldn't be disconnected during the role change of master/follower controllers.

Hi @hemant_singh
When there is a switch over from Active and Standby, the AP actually gets a new config push from the new Active Master and will overwrite its config causing the WLANs to delete and re-create.
Due to this behavior the clients will disconnect and re-connect.

Hi Sanjay Ji,

but we can see below in the unleashed Admin Guide there is clearly mentioned that when a fail-over occurs, all the associated AP's will continue to provide wireless services to the clients during the transition..... Please Clarify.

Hi @hemant_singh

For seamless switching of the APs and client connectivity, we recommend you to mention Primary and Secondary Masters under Admin & Services >> System Info >> Access Point Policies >>
Or
Use Option 43, to send the Primary and Secondary Masters IP to the APs.

Hi Sanjay,

all these parameters are already matched, but still we are getting the same issue. radios are being turned off and on again when fail-over occur. below are the logs which we have collected during the fail-over.

Hi @hemant_singh

Looks like the AP is running in SOLE RUN.

Could you please help me with the below command output from the Member AP
Note : Please make sure to take it when doing the failover and APs having issue.

get director

Can I do this option even tho my AP’s are using DHCP? Similar situation with the Original Poster.
