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

[manuel.bitzi]

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.
