    I am using 8.2.0.2 version for Mobility Master. While trying to enable DB synchronization for MM redundancy over L2 I get an error "cannot start database synchronization this command is applicable at node mobility master". I read somewhere that this error needs to be ignored but I am not able to commit the changes. Also while trying to do manual database synchronization through CLI it yields error on output for L2 synchronization. 

     

    I am able to get L3 synchronization up on the same MM over another one across L3 network.

    You have to execute the command from the top folder:
    (here) Mobility Master>
    MM1
    MM2

    Many thanks Victor, I seem to have the DB sync working now. However the sync is not happening plus neither are the switches showing up in either of the MM's.

     

    I have attached the output and 2 screens of configuration i.e. VRRP and DB sync. I even added NTP and DNS. What am I missing, some help please.

     

    Thanks in advance.
