DHCP Serverkonfiguration für Endgeräte mit Provisioning-URL

Gespeichert von root am/um 13 Januar, 2012 - 18:34

Einleitung

Das Phonalisa Provisioning erlaubt es, Endgeräte vollautomatisch zu konfigurieren. Damit die Endgeräte aber die URL bekommen, von der diese sich die Konfiguration beziehen können, muss man diese entweder per Hand eingeben (was bei größeren Installationen lässtig und aufwändig ist) oder per DHCP-Server deployen. 

Der DHCP-Server muss meist als Option 66 die TFTP-Boot URL setzen, diese nehmen die meisten Endgeräte als Provisioning URL.
