I have a problem with user tracking as I see IP phones only on a few of my switches.
Credential Check runs without any issues, DNS is working for the devices (both name -> IP and IP -> name)
I have deleted and readded the devices and run a discovery afterwards.
What I found is: going to acquisition (Admin> Collection Settings> User Tracking> Acquisition Action) and do a Device Selection I can select the switches but when I then start the acquisition I get an error "unreachable Device".
Deivce Unreachable Report shows no unreachable devices.
Do I miss something?
