Cisco Cisco Web Security Appliance S160 Guía Del Usuario

To upgrade from a local server, perform the following steps:

Configure a local server to retrieve and serve the upgrade files.

Download the upgrade zip file.

Using a browser on the local server, go to

 

http://updates.ironport.com/fetch_manifest.html

 to download a zip file of an upgrade image. To 

download the image, enter your serial number and the version number of the appliance. You will then be 
presented with a list of available upgrades. Click on the upgrade version that you want to download. 

Unzip the zip file in the root directory on the local server while keeping the directory structure intact.

Configure the appliance to use the local server using the System Administration > Upgrade and Update 
Settings page or the 

updateconfig

 command.

On the System Administration > System Upgrade page, click Available Upgrades or run the 

upgrade

 

command.

Cisco recommends changing the update and upgrade settings to use the Cisco IronPort update servers 
(using dynamic or static addresses) after the upgrade is complete to ensure the security service 
components continue to update automatically.

For downloading AsyncOS upgrade files, you must have a system in your internal network that has a 
web browser (see 

) and Internet access to the Cisco IronPort update 

servers. 

If you need to configure a firewall setting to allow HTTP access to this address, you must configure it 
using the DNS name and not a specific IP address.
