The Edit Update Settings page is displayed.
Step 2 Choose whether to download the AsyncOS upgrade image from the Cisco IronPort update servers or a
local server.
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.
Note 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become out of date.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.
Step 3 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.
Step 4 Select the interface to use for the upgrade.
Step 5 Enter HTTP proxy server or HTTPS proxy server information if desired.
Step 6 Submit and commit changes.
Configuring Upgrade Settings from the CLI
The updateconfig Command
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).
Note You can use the ping command to ensure that the appliance can contact the local server. You can also
use the telnet command to telnet to port 80 of the local server to ensure the local server is listening on
that port.
AsyncOS Reversion
AsyncOS includes the ability to revert the AsyncOS operating system to a previous qualified build for
emergency uses.
Note After upgrading to AsyncOS 7.0, you cannot revert to a version of AsyncOS earlier than 6.5.
