Enter options: 

Choose whether to download Cisco IronPort AsyncOS upgrade images and 
service updates from the Cisco IronPort update servers or a from a local 
server on your network. The default is the Cisco IronPort update servers for 
both upgrades and updates. 

To use the same settings for upgrades and updates, enter information in the 
visible fields. 

If you choose a local update server, enter the base URL and port number for 
the servers used to download the upgrades and updates. If the server 
requires authentication, you can also enter a valid user name and password.

To enter separate settings solely for AsyncOS upgrades and McAfee 
Anti-Virus definitions, click the Click to use different settings for 
AsyncOS link.

Cisco Intelligent Multi-Scan requires a second local server to 
download updates for third-party anti-spam rules.

To ensure that only upgrades and updates that are appropriate to your 
deployment are available to each appliance, Cisco IronPort generates a 
manifest list of the relevant files. 

Choose whether to download the lists of available upgrades and service 
updates (the manifest XML files) from the Cisco IronPort update servers or 
from a local server on your network. 

There are separate sections for specifying servers for updates and for 
AsyncOS upgrades. The default for upgrades and updates is the Cisco 
IronPort update servers. 

If you choose local update servers, enter the full path to the manifest XML 
file for each list, including the file name and HTTP port number for the 
server. If you leave the port field blank, AsyncOS uses port 80. If the server 
requires authentication, enter a valid user name and password. 

Enable automatic updates and the update interval (how often the appliance 
checks for updates) for Sophos and McAfee Anti-Virus definitions, Cisco 
Anti-Spam rules, Cisco Intelligent Multi-Scan rules, PXE Engine updates, 
Outbreak Filter rules, and time zone rules. 

Include a trailing s, m, or h to indicate seconds, minutes, or hours. Enter 0 
(zero) to disable automatic updates. 

You can only turn on automatic updates for DLP using the Security 
Services > RSA Email DLP page. However, you must enable 
automatic updates for all services first. See 

 for more 

information.
