what does this mean and how to solve it?
When doing an show arp all:
No MAC is displayed at an IP address.
Any help is welcome, thanks in advance 🙂

Yes, that is what I thought as well. But why isn't the table being refreshed automatic after a certain time?
I would expect that this entry would be deleted after the TTL?
(The device is still connected, but the MAC address is gone. Maybe device is defect, but not sure yet.
We are busy with further troubleshooting.)

Is it possible that there are devices that are still attempting to reach out to the device?
Have you removed the device IP from any virtual router configurations (if that was a next hop)
As long as devices on the network are attempting to communicate to or through the device, then the FW may continue to show.
You can always do a "clear arp all" to clear the table.
