The Auto Update Server provides a Web-based interface module inside CiscoWorks for upgrading device configuration files, software images, and PDM images. It is designed to interoperate with PIX MC to deploy the configuration files and to operate alone for updating PDM images.
AUS works off the principal of the devices (firewalls) periodically polling it for updates. If an update exists, the device requests to download the newer image or configuration file. Figure 14.5 displays the step-by-step flow of the PIX interacting with an AUS server.

The Web interface for the AUS is similar to PIX MC. It contains; Devices, Files (Images), Assignments, Reports , and Admin tabs are used to set up and configure the AUS system. Table 14.7 contains a brief description of each tab.

In this chapter, we talked about CiscoWorks as the main enterprise software management product that can incorporate several modules to configure firewalls. The Cisco PIX MC is used to create groups of devices with similar attributes and provide configuration files. These configuration files can then be downloaded to the devices using the AUS feature of CiscoWorks.
