Cisco Cisco Web Security Appliance S170 사용자 가이드

Before you start the upgrade, save the XML configuration file off the Web Security appliance from 
the System Administration > Configuration File page or by using the 

saveconfig

 command. For 

more information, see 

When upgrading, do not pause for long amounts of time at the various prompts. If the TCP session 
times out during the download, the upgrade may fail.

Consider saving other files stored on the appliance, such as PAC files or customized end-user 
notification pages.

Consider saving the configuration information to an XML file after the upgrade completes, too. 

You can configure the Web Security appliance to display a message at the top of the web interface notify 
you that an upgrade to AsyncOS is available for the appliance. AsyncOS displays this notification for 
any administrator logged into the appliance.

Hover over the notification with your mouse cursor to view the number of upgrades available for the 
appliance and the version and build number of the latest available upgrade.

Click the down arrows in the lower right corner to expand the notification window. The window displays 
a link to the System Administration > System Upgrade page for you to start the upgrade.

To dismiss the message, check the Clear the notification check box and click Close. The appliance will 
not display another notification until a new upgrade becomes available.

You can enable these notifications on your appliance using the System Administration > Upgrade and 
Update Settings page. See 

 for more 

information.
