Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

If the feature key for the feature you are trying to access (via the GUI) has expired, please contact your 
Cisco representative or support organization.

The Cisco Email Security Virtual appliance requires an additional license to run the virtual appliance on 
a host. You can use this license for multiple, cloned virtual appliances.

To install this license, run the 

loadlicense

 CLI command. You can either copy and paste the license into 

the CLI or upload it onto the appliance’s 

configuration

 directory using FTP before running the 

command. It must be installed on the appliance before running the System Setup Wizard.

You cannot open a Technical Support tunnel before installing the virtual appliance license.

For complete information on licensing, setting up, and running the Email Security Virtual appliance, see 
the Cisco Content Security Virtual Appliance Installation Guide. This document is available from the 
location noted in

After the virtual appliance license expires, the appliance will continue to deliver mail without security 
services for 180 days. Security service updates do not occur during this period. 

Alerts will be sent 180 days, 150 days, 120 days, 90 days, 60 days, 30 days, 15 days, 5 days, 1 day and 
0 seconds before the license expires, and at the same intervals before the grace period ends. These alerts 
will be of type “System” at severity level “Critical.” To ensure that you receive these alerts, see 

These alerts are also logged in the system log. 

All configuration settings within the appliance can be managed via a single configuration file. The file 
is maintained in XML (Extensible Markup Language) format. 

You can use this file in several ways: 

You can save the configuration file to a different system to back up and preserve crucial 
configuration data. If you make a mistake while configuring your appliance, you can “roll back” to 
the most recently saved configuration file. 

You can download the existing configuration file to view the entire configuration for an appliance 
quickly. (Many newer browsers include the ability to render XML files directly.) This may help you 
troubleshoot minor errors (like typographic errors) that may exist in the current configuration.
