Cisco Cisco IPS 4255 Sensor 릴리즈 노트

Whenever you start the IDM, the IME, or the CLI, 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 the IDM, the IME, and the CLI, but you cannot download signature 
updates.

If you already have a valid license on the sensor, you can click Download on the License pane to 
download a copy of your license key to the computer that the IDM or the IME is running on and save it 
to a local file. You can then replace a lost or corrupted license, or reinstall your license after you have 
reimaged the sensor.

You must have a Cisco Services for IPS service contract for any IPS product so that you can download 
a license key and obtain the latest IPS signature updates. If you have a direct relationship with Cisco 
Systems, contact your account manager or service account manager to purchase the Cisco Services for 
IPS service contract. If you do not have a direct relationship with Cisco Systems, you can purchase the 
service account from a one-tier or two-tier partner.

When you purchase the following IPS products you must also purchase a Cisco Services for IPS service 
contract:

IPS 4240

IPS 4255

IPS 4260

IPS 4270-20

AIM IPS

IDSM2

NME IPS

When you purchase an ASA 5500 series adaptive security appliance product that does not contain IPS, 
you must purchase a SMARTnet contract.

SMARTnet provides operating system updates, access to Cisco.com, access to TAC, and hardware 
replacement NBD on site.

When you purchase an ASA 5500 series adaptive security appliance product that ships with the AIP SSM 
installed, or if you purchase it to add to your ASA 5500 series adaptive security appliance product, you 
must purchase the Cisco Services for IPS service contract.

Cisco Services for IPS provides IPS signature updates, operating system updates, access to Cisco.com, 
access to TAC, and hardware replacement NBD on site. 

For example, if you purchase an ASA-5510 and then later want to add IPS and purchase an 
ASA-SSM-AIP-10-K9, you must now purchase the Cisco Services for IPS service contract. After you 
have the Cisco Services for IPS service contract, you must also have your product serial number to apply 
for the license key.

If you ever send your product for RMA, the serial number changes. You must then get a new license key 
for the new serial number.
