Cisco Cisco Web Security Appliance S170 사용자 가이드

The 

updateconfig

 command is used to configure update and upgrade settings, such as where the 

appliance looks for service updates and AsyncOS upgrades. The settings you configure using the 

updateconfig

 command are the same as you can define in the web interface. For more information on 

these settings, see 

You can use the 

ping

 command to ensure that the appliance can contact the local server. You can also 

use the 

telnet

 CLI command to telnet to port 80 of the local server to ensure the local server is listening 

on that port. 

By default, each security service component periodically receives updates to its database tables from the 
Cisco IronPort update servers. However, you can manually update the database tables. 

Typically, you do not need to manually update to the database tables. In the event a manual update is 
required, you can modify default settings and configure an update using the options on the System 
Administration > Upgrade and Update Settings page.

Some updates are available on an on-demand basis from the GUI pages related to the feature. For 
example, to manually update only the set of URL categories, see 

Navigate to the System Administration > Upgrade and Update Settings page.

Click Edit Update Settings.

Specify the location of the update files.

Initiate the update using the Update Now function key on the component page located on the Security 
Services tab. For example, Security Services > Web Reputation Filters page.

Updates that are in-progress cannot be interrupted. All in-progress updates must complete before new 
changes can be applied. 

View a record of update activity in the updater log file. Subscribe to the updater log file on the System 
Administration > Log Subscriptions page.

AsyncOS for Web supports the ability to revert the AsyncOS for Web operating system to a previous 
qualified build for emergency uses.
