Abstract

A configuration manager for configuring a network device remotely coupled thereto and an associated computer-implemented method for configuring the network device. The configuration manager includes a configuration script stored in a memory subsystem of a computer system and first and second software modules respectively executable by a processor subsystem of the computer system. The configuration script contains a series of executable instructions for constructing a configuration file and a bootptab file for a first specified type of network device. By executing the instructions contained in the configuration script, the first software module may construct a configuration file suitable for upload to a network device and a bootptab file suitable for identifying the network device. Configuration requests issued by the network device are processed by the second software module by identifying the requesting network device using the constructed bootptab file and configuring the requesting network device by uploading the constructed configuration file thereto.
