Dhcp Server - Siemens SCALANCE XB-200 Configuration Manual

5.4.8.2

DHCP Server

You can operate the device as a DHCP server. This allows IP addresses to be assigned
automatically to the connected devices. The IP addresses are either distributed dynamically
from an address band (pool) you have specified or a specific IP address is assigned to a
particular device.
On this page, specify the address band from which the connected device receives any IP
address. You configure the static assignment of the IP addresses in "Static Leases".
Requirement
The connected devices are configured so that they obtain the IP address from a DHCP
server.
Description
The page contains the following boxes:
● DHCP Server
Enable or disable the DHCP server on the device.
Note
To avoid conflicts with IPv4 addresses, only one device may be configured as a DHCP
server in the network.
● Probe address with ICMP echo before offer
When selected, the DHCP server checks whether or not an IP address has already been
assigned. To do this the DHCP server sends ICMP echo messages (ping) to this IPv4
address. If no reply is received, the IPv4 address is assigned.
Note
If there are devices in your network on which the echo service is disabled as default,
there may be conflicts with the IPv4 addresses. To avoid this, assign these devices an
IPv4 address outside the IPv4 address band used by the DHCP server.
