In the older versions, I could discover one device and automatically it would
discover all neighbor devices as well within a site. The newest version doesn't
seem to do this. Am I doing something wrong?
Let's say I have a small site with 30 switches wanted to discover all 30
devices (all within 10.119.1.0/24). Per the directions to discover one device:
netdisco-do -D discover -d 10.119.1.1. After this single device is complete,
it stops.

Thanks Oliver,
I have changed to the newer and higher-rated docker image from irasnyd
(https://hub.docker.com/r/irasnyd/netdisco/).
This one worked fine and discovered the network ok without any additional
configuration needed.
Happy new year!

Hi Christoph
The Netdisco MIBs bundle is not installed. On the Netdisco homepage
there are instructions which will help.
I suggest you ask the creator of that docker image for assistance - this
is sheeprine?
regards,
oliver.
