Cisco ISE Licensing in plain words

Maybe I can summarize the description in this post as below.

No worry at all when exceeding device license count.

You can continue to manage and use ISE to authenticate and authorize network uses even when you run out of licenses count. The only inconveniences are the annoying warnings.
If you've reached limits of your current license, you also need to obtain new license. It could be completely new license, or an upgrade. ISE implements the concept of soft limits. So the system will throw "license enforcement" alarms (see http://www.cisco.com/en/US/docs/security/ise/1.0.4/user_guide/ise10_mnt.html).

Important note: ISE is not locked when license is overhelmed.



You will be locked out of administration if the license expires.

For time-based licenses, such as Advanced License and Wireless License, you will be locked out of administration after expiration. It is not that urgent to apply a new licenses immediately because ISE continues to authenticate and authorize network uses as usual.
If the license is expired, when your system becomes locked for administration. However, users are continue to authenticate, so you have a possibility to order new license and apply it without risk of downtime.
