I dont think it is required to be in the same subnet, configuration sync requires time on both devices to be sync. here is a link that helps troubleshooting configuration sync issues https://support.f5.com/csp/article/K13946.

    Hi Kevin, thanks for the response.

     

    1. Currently the 2 boxes have discovered each other while forming Device Trust using the management IPs.

       

    2. Physical 'A' box is Online(Active) and we have kept VM 'B' box in Forced offline state. Both boxes show 'Dsiconnected'.

       

    My physical box is on hardware 1600 and VM is on 7200 hardware. I see different Licenses for the 2 boxes, could this be the reason?
