Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Issue the 

upgrade

 command to show a list of available upgrades. Select the 

desired upgrade from the list to install it. You may be asked to confirm messages 
or read and agree to license agreements, etc. You can choose whether or not to 
save the current configuration to the 

configuration

 directory. If so, you can 

choose whether or not to mask the passwords in the configuration file. You can 
also choose to email a copy of the configuration files.

You cannot load a configuration file with masked passwords using the 

loadconfig

 

command.

When upgrading, do not pause for long amounts of time at the various prompts. 
If the TCP session should happen to time out during the download, your upgrade 
may fail.

Please note these differences when upgrading AsyncOS from a local server as 
opposed to the traditional method: 

The upgrading installs immediately while downloading. 

A banner displays for 10 seconds at the beginning of the upgrade process. While 
this banner is displayed, you have the option to type Control-C to exit the upgrade 
process before downloading starts. 

You can configure how the Email Security appliance downloads AsyncOS 
upgrades. IronPort provides two methods (or “sources”) for upgrading: streaming 
upgrades and remote upgrades.

With streaming upgrades, your Cisco IronPort appliances download the AsyncOS 
upgrades directly from the Cisco IronPort update servers. Each Cisco IronPort 
appliance downloads the upgrade separately. For more information, see
