2.7 System configuration via
DHCP Option 82
As with the classic DHCP, on startup an agent receives its configuration data
according to the "BOOTP/DHCP process" flow chart
(see fig. 13) .
While the system configuration is based on the classical DHCP protocol (see
on page 46 „System Configuration via DHCP“) on the device being config-
ured, Option 82 is based on the network topology. This procedure gives you
the option of always assigning the same IP address to any device which is
connected to a particular location (port of a device) on the LAN.
The installation of a DHCP server is described in the chapter
„Setting up
DHCP Server Option 82“ on page 186 .
