In addition to predefined option codes, the codes 0, 255, and 53 cannot be used to
create a custom DHCP option. All other integers between 2 and 254 are valid.
Data Type—The type of data required for the option code. Available data types are
string, IP address, and integer.
Value—The value of the option code. When the data type is string, the acceptable
length is 1-128 characters.
Your network recently added support for VoIP, and you now need to support DHCP for
VoIP phones. You edit the existing DHCP server configuration to send the following
custom options to IP phones acting as DHCP clients:
Option code 444, containing string "Server 4"
Option code 66, containing IP address 1.1.1.1
Option code 160, containing integer 2004
The example assumes that you have already configured a security device to act as a
DHCP server.

In the NSM navigation tree, select Device Manager > Devices. Double-click the device
