Disconnected switches
Disconnected switches
Team,
About 4-6 weeks ago the switches received the latest firmware.
Since then, every (scheduled) reboot leaves some of them in a disconnected state.
The EAP's and the router are always coming back in the connected state.
Even when the switches they are connected to have a disconnected state.
Switching the disconnected switches off and on doesn't bring them back in a connected state.
The same applies when restarting the controller.
What makes this interesting is that the ping to the IP addresses mentioned in the controller works.
In addition the behavior of the network is also as expected - this includes lights-off, vlans, ACL's and PoE.
Based on this it looks like the running config before the scheduled reboot is active.
Also because the connected EAP's and router are showing "connected".
The only way to get the switches connected again is a reset to factory defaults.
Which is rather annoying - in particular for the switch model mentioned previously.
Because a reset to factory defaults can only be done via the console cable.
Does this ring any bells?
Any suggestion on getting them connected again without a factory reset?
With warm regards,
- Will

Hi @ITV
Thanks for posting in our business forum.

Remoting is possible - please note that I'm on the Amsterdam timezone.
I also have made a backup of the controller config and its logs.
One with all devices connected. And one with 2 switches disconnected after a reboot with new firmware.
These two switches are labelled sw-3 (SG2218) and sw-4 (SG2008P).
How do you want me to share these logs and backup configs?
With warm regards - Will

You hinted to a problem with the controller.
In my case the controller is the latest version of the Docker container.
The problem was gone after switching from bridge-mode to host-mode.
Thank you for your time and patience.
