Cisco Cisco NAC Appliance 4.7.3 Installation Guide

Before deploying the CAM or CAS in a production environment, you can obtain a trusted certificate 
from a Certificate Authority to replace the temporary certificate. A CA-signed certificate for the 
CAS prevents the security warning when end users log in and a CA-signed certificate for the CAM 
prevents the admin web login security warning.

Make sure to synchronize the time on the CAM and CAS via the web console interface before 
regenerating a temporary certificate on which a Certificate Signing Request (CSR) will be based. 
For further details see the “Set System Time” and “Manage SSL Certificates” sections of the CAM 
and CAS guides.

This section contains the following information:

The tables in these sections show only common router and network module commands.

To view a complete list of available commands, type ? at the prompt
(Example: 

Router(config-if)# ?

).

To view a complete list of command keyword options, type ? at the end of the command
(Example: 

Router# service-module integrated-service-engine ?

).

The tables group commands by the configuration mode in which they are available. If the same 
command is available in more than one mode, it may act differently in each mode.

To shut down or start up the Cisco NAC network module or the Clean Access Server application that 
runs on the module, use commands as needed from the following list of common router and network 
module commands (

).

Some shutdown commands can potentially disrupt service. If command output for such a command 
displays a confirmation prompt, confirm by pressing Enter or cancel by typing n and pressing 
Enter. Alternatively, prevent the prompt from displaying by using the no-confirm keyword.

Some commands shut the module or application down and then immediately restart it.
