Abstract

A system and method of allowing a network device to receive a customized version of a reference design is disclosed. In one embodiment, many values that may be subject to customization are no longer fixed by the reference design. Rather, the reference design utilizes rewritable non-volatile memory to store a set of customization values that can be changed, based on a customer's preference. The system also includes a configuration tool, which interfaces with the network device. Using vendor-unique commands, the configuration tool is able to initialize this set of customization values to the values requested by the customer. In operation, the reference design is downloaded into the network device. The configuration tool is then used to establish the customized parameters for a particular customer. This process allows the manufacturer to create one reference design, which can be customized without the need to modify the code or recompile the source code.

Dependent claims

A method of modifying customizable parameters within a network device, the network device configured to operate as part of a network, the method comprising:

establishing a network connection between the network device and a configuration tool, using a first network protocol;
issuing an unlock sequence from the configuration tool to the network device using the network connection, wherein the unlock sequence is required to allow access to a nonvolatile memory in the network device so that new values may be written to the nonvolatile memory;
downloading new values for the customizable parameters from the configuration tool to the network device using the network connection;
and
storing the new values in the nonvolatile memory in the network device.
