For the procedure for initializing the sensor, refer to 

For the procedure for changing the Java memory heap size, see 

For the procedure for licensing the sensor, see 

This section describes how to obtain a license key and how to license the sensor using the CLI or IDM. 
It contains the following topics:

Although the sensor functions without the license key, you must have a license key to obtain signature 
updates. To obtain a license key, you must have the following:

Cisco Service for IPS service contract

Contact your reseller, Cisco service or product sales to purchase a contract.

Your IPS device serial number 

To find the IPS device serial number in IDM, choose Configuration > Licensing, or in the CLI use 
the show version command.

Valid Cisco.com username and password

Trial license keys are also available. If you cannot get your sensor licensed because of problems with 
your contract, you can obtain a 60-day trial license that supports signature updates that require licensing.

You can obtain a license key from the Cisco.com licensing server, which is then delivered to the sensor. 
Or, you can update the license key from a license key provided in a local file. Go to 

 and click IPS Signature Subscription Service to apply for a license 

key. 

You can view the status of the license key on the Licensing pane in IDM. Whenever you start IDM, you 
are informed of your license status—whether you have a trial, invalid, or expired license key. With no 
license key, an invalid license key, or an expired license key, you can continue to use IDM but you cannot 
download signature updates.
