    Hi
    Im getting an message : Cannot start database synchronization: peer is not configured

    What that means? VRRP is up, I can see both controllers Up. I’ve added one Wlc as MD in MM environment and everything seem to be fine but

    This Controller with show switches has
    Configuration State : Last Snapshot
    Config ID : -1

    Do you have Standby Mobility Master, can you give more information about your setup?
    how many controllers (MDs)
    how many mobility masters/Conductors (MM)?

    You have to configure master (conductor) redundancy, in addition to configuring a VRRP, to have database synchronization work.  https://www.arubanetworks.com/techdocs/ArubaOS_8.10.0_Web_Help/Content/arubaos-solutions/vrrp/conf-stby-mm-l2red.htm?Highlight=master%20redundancy

    Database synchronization only occurs between Active and Standby MMs (masters).  You cannot do Database synchronization between two active MMs (masters).

    Hi

    Mobility Master = Mobility Conductor. The nomenclature changed time before. Hence, do you refer that have 2 MMs (Master or conductor) and 2 MDs (controllers) ?

    If the answer is yes. The configuration occurs from MM to MDs and you need configure data syncronization between MMs as Joseph told you.

    Hi
    Yes I understandt the point. I'm going to reset the wlc-2 having issues and doing the "write erase" and build the connection from zero to check if I've done something wrong from the beginning
