Chapter 4 Managing Feature Licenses
Activating or Deactivating Keys
Step 3 Enter the following information, when prompted:
• Product Authorization Key (if you have multiple keys, enter one of the keys first. You have to enter
each key as a separate process.)
• The serial number of your adaptive security appliance
• Your email address
An activation key is automatically generated and sent to the email address that you provide. This key
includes all features you have registered so far for permanent licenses. For time-based licenses, each
license has a separate activation key.
Step 4 If you have additional Product Authorization Keys, repeat Step 3 for each Product Authorization Key.
After you enter all of the Product Authorization Keys, the final activation key provided includes all of
the permanent features you registered.
Activating or Deactivating Keys
This section describes how to enter a new activation key, and how to activate and deactivate time-based
keys.
Prerequisites
• If you are already in multiple context mode, enter the activation key in the system execution space.
• Some permanent licenses require you to reload the adaptive security appliance after you activate
them. Table 4-10 lists the licenses that require reloading.
Limitations and Restrictions
Your activation key remains compatible if you upgrade to the latest version from any previous version.
However, you might have issues if you want to maintain downgrade capability:
• Downgrading to Version 8.1 or earlier—After you upgrade, if you activate additional feature
licenses that were introduced before 8.2, then the activation key continues to be compatible with
earlier versions if you downgrade. However if you activate feature licenses that were introduced in
8.2 or later, then the activation key is not backwards compatible. If you have an incompatible license
key, then see the following guidelines:
–
If you previously entered an activation key in an earlier version, then the adaptive security
appliance uses that key (without any of the new licenses you activated in Version 8.2 or later).
–
If you have a new system and do not have an earlier activation key, then you need to request a
new activation key compatible with the earlier version.
