Version 4.4 189 July 2005
Appendix B The BootP/TFTP Configuration Utility
The BootP/TFTP utility enables you to easily configure and provision our boards and media
gateways. Similar to third-party BootP/TFTP utilities (which are also supported) but with added
functionality; our BootP/TFTP utility can be installed on Windows™ 98 or Windows™
NT/2000/XP. The BootP/TFTP utility enables remote reset of the device to trigger the initialization
procedure (BootP and TFTP). It contains BootP and TFTP utilities with specific adaptations to our
requirements.
B.1 When to Use the BootP/TFTP
The BootP/TFTP utility can be used with the device as an alternative means of initializing the
gateways. Initialization provides a gateway with an IP address, subnet mask, and the default
gateway IP address. The tool also loads default software, ini and other configuration files. BootP
Tool can also be used to restore a gateway to its initial configuration, such as in the following
instances:
• The IP address of the gateway is not known.
• The Web browser has been inadvertently turned off.
• The Web browser password has been forgotten.
• The gateway has encountered a fault that cannot be recovered using the Web browser.
Tip: The BootP is normally used to configure the device’s initial parameters. Once
this information has been provided, the BootP is no longer needed. All
parameters are stored in non-volatile memory and used when the BootP is
not accessible.
B.2 An Overview of BootP
BootP is a protocol defined in RFC 951 and RFC 1542 that enables an internet device to discover
its own IP address and the IP address of a BootP on the network, and to obtain the files from that
utility that need to be loaded into the device to function.
A device that uses BootP when it powers up broadcasts a BootRequest message on the network.
A BootP on the network receives this message and generates a BootReply. The BootReply
indicates the IP address that should be used by the device and specifies an IP address from
which the unit may load configuration files using Trivial File Transfer Protocol (TFTP) described in
RFC 906 and RFC 1350.
