Cisco Cisco Content Security Management Appliance M1070 Mode D'Emploi

Note these differences when upgrading AsyncOS from a local server (Remote upgrade) as opposed to 
the Streaming upgrade method: 

The upgrade installs immediately while downloading. 

A banner appears for 10 seconds at the beginning of the upgrade process. While this banner appears, 
you have the option to press Control-C to exit the upgrade process before downloading starts. 

You can configure how the Cisco Content Security appliance downloads security services updates (such 
as time zone rules) and AsyncOS upgrades. For example, you can choose whether to download upgrades 
and updates dynamically from Cisco servers or from a local server onto which you have made the images 
available; configure the update interval; or disable automatic updates. 

AsyncOS periodically queries the update servers for new updates to all security service components 
except for new AsyncOS upgrades. To upgrade AsyncOS, you must manually prompt AsyncOS to query 
for available upgrades.

You can configure upgrade and updates settings in the GUI (see the following two sections) or using the 

updateconfig

 command in the CLI. 

You can also configure upgrade notification settings.
