    Switch has no users on it, is this normal? And what is VIDL,bLK1 and other tasks, where I can read about them?

    I discussed this few years ago with a member of the R&D. They will not publish a processlist.

     

    But to your question:

    VIDL: Idle process as every OS has it.

    bLK0/1: Scheduled process to observe the port states and changes.

     

    This behavior is normal and does not effect the forwarded traffic.
