Cisco Cisco IPS 4255 Sensor

This section describes how to initialize the sensor using the setup command, and contains the following 
sections:

You must be administrator to use the setup command.

After you install the sensor on your network, you must use the setup command to initialize it so that you 
can communicate with it over the network. You cannot use the IDM or the IME to configure the sensor 
until you initialize the sensor using the setup command.

With the setup command, you configure basic sensor settings, including the hostname, IP interfaces, 
access control lists, global correlation servers, and time settings. You can continue using advanced setup 
in the CLI to enable Telnet, configure the web server, and assign and enable virtual sensors and 
interfaces, or you can use the Startup Wizard in the IDM or the IME. After you configure the sensor with 
the setup command, you can change the network settings in the IDM or the IME.

You must have a valid sensor license for global correlation features to function. You can still configure 
and display statistics for the global correlation features, but the global correlation databases are cleared 
and no updates are attempted. Once you install a valid license, the global correlation features are 
reactivated.

The sensor automatically calls the setup command when you connect to the sensor using a console cable 
and the sensor basic network settings have not yet been configured. The sensor does not call automatic 
setup under the following conditions: 

When initialization has already been successfully completed.

If you have recovered or downgraded the sensor. 

If you have set the host configuration to default after successfully configuring the sensor using 
automatic setup.
