Cisco Cisco Email Security Appliance C190 User Guide

You can administer the Cisco appliance using both the web-based Graphical User Interface (GUI) and 
Command Line Interface (CLI). The GUI contains most of the functionality you need to configure and 
monitor the system. However, not all CLI commands are available in the GUI; some features are only 
available through the CLI. 

To access the web-based UI, your browser must support and be enabled to accept JavaScript and cookies, 
and it must be able to render HTML pages containing Cascading Style Sheets (CSS). 

Beginning with AsyncOS 5.5, the web-based UI incorporates libraries from the Yahoo! User Interface 
(YUI) Library, which is a set of utilities and controls, written in JavaScript, for building richly interactive 
web applications. The purpose of this change is to provide an improved user experience in the web-based 
UI. 

The YUI library supports the vast majority of browsers that are in general use. The YUI library also has 
a comprehensive, public approach to browser support and is committed to making sure that components 
work well in all of what are designated as "A-Grade" browsers. For more information on graded browser 
support, see:
