Device Images Overview
An image management system provides full lifecycle management of images for all network devices, including CPE device and virtualized network function (VNF) images. A device image is a software installation package for the CPE device or an image for a virtual application that runs on the device. For example, for a NFX Series device platform, you require an NFX software image and a software image for the vSRX Virtual Firewall application that provides security functions and routing on the device.
