Cisco Cisco Email Security Appliance C170 사용자 가이드

If you choose a local server, enter the base URL for the local server hosting 
the AsyncOS upgrade image. If the server requires authentication, you can 
also enter a valid user name and password.

When you specify a local server for AsyncOS upgrades, the local server 
does not automatically receive updated McAfee Anti-Virus definitions, so 
the appliances in your network eventually become out of date. Change the 
settings back to use the Cisco IronPort update servers after the upgrade so 
the McAfee Anti-Virus definitions update automatically again.

If you choose to download the AsyncOS upgrade image from a local server, select 
the local server as the source for the list of available updates (the manifest XML 
file). Enter the full URL for the manifest, including the file name, and the HTTP 
port number. If the server requires authentication, you can also enter a valid user 
name and password.

Select the interface to use for the upgrade.

Enter HTTP proxy server or HTTPS proxy server information if desired.

Submit and commit changes.

To tell your appliances where to retrieve the AsyncOS upgrade (local or from 
Cisco IronPort’s servers), run the 

updateconfig 

command. To install an upgrade, 

run the 

upgrade

 command.

The 

updateconfig

 command is used to tell your Cisco IronPort appliance where 

to look for service updates, including AsyncOS upgrades. By default, when you 
type the 

upgrade

 command, the appliance will contact Cisco IronPort’s upgrade 

servers for the latest update. For remote upgrades, issue the 

updateconfig

 

command and configure the appliance to use a local update server (the local server 
configured above).
