AUS Page
The AUS page lets you configure remote updating of a security appliance from a server that supports the
Auto Update specification. Auto Update applies configuration changes and software updates to the
appliance automatically from the remote server.
Note The server you identify on this page must be the same server you identify in the Auto Update section of
the Device Properties (from the Tools menu, choose Device Properties). The Device Properties
information identifies the AUS server to which Security Manager sends configuration updates, whereas
the information on this page defines for the server the device will contact for updates. Also, the Device
Identity you provide in the Device Properties must match the Device ID on this page.
If you change AUS servers, note that the device will continue to use the AUS server defined in its current
configuration until it receives a new configuration. Thus, you should change the AUS policy but deploy
the configuration using the previous AUS server. After deployment is successful, change the Device
Properties to point to the new server. For more information on deploying to AUS, see Deploying
Configurations Using an Auto Update Server or CNS Configuration Engine, page 8-42.
