Chapter 8: DHCP Server Administration
Avaya IP Telephones are usually configured remotely to enable downloading the appropriate 
configuration files. Normal, dynamically assigned IP configurations need a DHCP server to 
allocate IP addresses to the telephones, as opposed to static assignment. The DHCP server 
can either be a separate Windows/Linux server or be configured on the same server as the 
Avaya IP Telephone File Server Application.
The DHCP server also allows the HTTP server address, meaning the IP Telephone File Server 
Application server, to be set for the telephones.

The most important setting is to ensure that the telephone knows the correct IP 
address of the HTTP settings file download from the IP Telephone File Server 
Application server.
For information about DHCP setup and for general administrative information, see the Avaya 
one-X™ Deskphone Edition for 9600 Series IP Telephones Administrator Guide 
or the 4600 
Series IP Telephone Administrator Guide
 as applicable. The guides are available on the Avaya 
support site 
For more information about setting up the DHCP server on RedHat Linux, see the RedHat 
manual by typing man dhcp-options in a command shell window.
Essentially you need to:
1. Configure the /etc/dhcpd.conf file to the required settings for your specific IP address 
assignments. A text editor like KWrite can be helpful.
2. Start the dhcpd daemon and ensure that it starts automatically on reboot. 
Here is a simple example of a /etc/dhcpd.conf file:
# A simple config file
default-lease-time 720;
max-lease-time 86400;
option subnet-mask 255.255.0.0;
option broadcast-address 192.168.255.255;
option routers 192.168.0.254;
option domain-name-servers 192.168.0.1, 192.168.0.2;
option tftp-server-name “MV_Server1”;
range 192.168.0.10 192.168.0.253
To ensure that the dhcpd daemon runs on startup, access the Service Configuration application 
from the GUI. Select MenuSystem SettingsServer Settings, and Services. Verify that the 
“dhcpd” service is checked.
