In DHCP mode, a completely unconfigured device can even automatically
assign IP addresses to itself and the computers in the network.
In the simplest case, all that is required is to connect the new device to a
network without other DHCP servers and switch it on. The DHCP server then
interacts with
ELSA LANconfig using a wizard and handles all of the address
assignments in the local network itself.
4.4.2 DHCP – 'on', 'off' or 'auto'?
The DHCP server can be set to three different states:
'on': The DHCP server is permanently active. The configuration of the
server (validity of the address pool) is checked when this value is entered.
When correctly configured, the device will be available to the
network as a DHCP server.
In the event of an incorrect configuration (e.g. invalid pool limits), the
DHCP server is disabled and switches to the 'off' state.
'off': The DHCP server is permanently disabled.
'auto': The server is in automatic mode. In this mode, after switching it
on, the device looks for other DHCP server within the local network.
The device then disables its own DHCP server if any other DHCP
servers are found. This prevents the unconfigured device from
assigning addresses not in the local network when switched on.
The device then enables its own DHCP server if no other DHCP
servers are found.
Whether the DHCP server is active or not can be seen in the DHCP
statistics.
The default state is 'auto'.
4.4.3 How are the addresses assigned?
IP address assignment
Before the DHCP server can assign IP addresses to the computers in the
network, it first needs to know which addresses are available for assignment.
Three options exist for determining the available selection of addresses:
The IP address can be taken from the address pool selected (start address
pool to end address pool). Any valid addresses in the local network can
be entered here.
