Cisco Cisco Email Security Appliance C190 User Guide

Cisco Email 
Security Virtual 
Appliance

Cisco offers the Cisco Email Security appliance as a virtual machine that you can 
host on your own network. 

The virtual appliance requires a separate license purchased from Cisco and a Cisco 
UCS Server (Blade or Rack-Mounted) hardware platform running VMware ESXi 
version 4.x. 

The Cisco Content Security Virtual Appliance Installation Guide includes more 
information on the requirements for the virtual appliance.

See the Cisco Content Security Virtual Appliance Installation Guide or the release 
notes for a list of the virtual appliance models available.

This feature includes the following changes to AsyncOs for Email:

The Email Security virtual appliance license allows you to clone and run 
multiple virtual appliances on your network.

The 

loadlicense

 CLI command for installing the virtual appliance license. 

You can use the same license for multiple virtual appliances.

Feature keys are included as part of the virtual appliance license. The feature 
keys will expire at the same time as the license. Purchasing new feature keys 
will require downloading and installing a new virtual appliance license.

Due to feature keys being included in the virtual appliance license, there are no 
30-day evaluations for AsyncOS features such as Cisco Anti-Spam or Outbreak 
Filters.

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

The 

version

, 

ipcheck

, and 

supportrequest

 CLI commands have also been 

updated to included virtual appliance information.

There are new alerts and logs for misconfigured virtual appliances.

Other differences between the physical and virtual appliances will be noted in this 
guide when necessary.
