DHCP server configuration
Example 1: Configuration file
The following format must be used for encoding the Voice Gateway Media Card information.
In addition to the configuration statements provided, other network and subnet declarations
must also be included in the configuration file. As mentioned in the beginning of this section,
read the man files and use the following example as a guideline:
# File name: dhcpd.conf
# Location: /etc/
# Description: Configuration file for ISC dhcpd server
# Author: Cecilia Mok
# Date: September 24, 1999
# Global option definitions common for all supported
# networks...
default-lease-time 300;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 255.255.255.255;
# Defining Nortel-specific option for 2004 IP Phone client
option my-vendor-specific-info code 144 = string;
# Declaring a class for IP Phones type 2002, 2004, and 2007
# clients.
# Add new clients to the class if their Class Identifier
# match the special 2004 IP Phone ID string.
class "i2004-clients"
{
match if option vendor-class-identifier =
4e:6f:72:74:65:6c:2d:69:32:30:30:34:2d:41:00;
}
# Declaring another class for PC clients
class "pc-clients"
{}
# Declaring a shared network
# This is to accommodate two different sub-nets on the same
# physical network; see dhcpd.conf.man5 for more details
shared-network "myNetwork"
{
# Declaring subnet for current server

a. Use the vendor-encapsulated-options option (as in the previous
example) to encode the information as a sub option.
b. Define a Site Specific option to carry the necessary information. To
define a site specific option:
• give a declaration in the form of the name of the option, the option
code, and the type of data it carries outside any pool or network
declarations. For example:
option model-specific-info code 144 = string;
• replace the vendor-encapsulated option inside the pool statement
with the definition,
option model-specific-info = "Nortel É";
