In such situations, the DHCP (Dynamic Host Configuration Protocol) is the
ideal solution. Using this protocol, a DHCP server in a TCP/IP-based LAN can
dynamically assign the necessary addresses to the individual stations.
6.4.1 The DHCP server
As a DHCP server, the ELSA LANCOM Business can administer the IP
addresses in its TCP/IP network. In doing so, it passes the following
parameters to the workstation computers:
IP address
Network mask
Broadcast address
DNS server
NBNS
Default gateway
Period of validity for the parameters assigned
The DHCP server takes the IP addresses either from a freely defined address
pool or determines the addresses automatically from its own IP address (or
intranet address).
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.
6.4.2 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.
