The following table lists the combination rules for eachfeature license.NoteEven when the permanent license is used, if thetime-based license is active, it continues to count down.Table 1. How the permanent and time-based licenses combine depends onthe type of license. The system clock setting does not affect the license only ASAuptime counts towards the license duration.How Permanent and Time-Based Licenses CombineWhen you activate a time-based license, thenfeatures from both permanent and time-based licenses combine to form therunning license. The time-based license only counts down when theASA is running. The timer only starts again when you reactivate the time-basedlicense.If the time-based license is active, and you shut down the ASA, thenthe timer stops counting down. For example, if an evaluation license includes the Botnet Traffic Filter and a 1000-sessionAn圜onnect Premium license, you cannot also activate a standalone time-based 2500-session An圜onnect Premium license.How the Time-BasedLicense Timer Works.The timer for the time-based license starts counting down when youactivate it on the ASA.If you stop using the time-based license before it times out, thenthe timer halts. For example, if you install a 1000-session An圜onnectPremium license, and a 2500-session An圜onnect Premium license, then only one of these licenses can be active.If you activate an evaluation license that has multiple features in the key, then you cannot also activate another time-basedlicense for one of the included features. The inactive license remains installed, and ready for use. However, only one time-basedlicense per feature can be active at a time. If you also install time-based licenses, the ASA combines the permanent and time-based licenses into a running license.Related ConceptsTime-BasedLicensesIn addition to permanent licenses, you can purchase time-basedlicenses or receive an evaluation license that has a time-limit.įor example,you might buy a time-based An圜onnect Premium license to handle short-termsurges in the number of concurrent SSL VPN users, or you might order a BotnetTraffic Filter time-based license that is valid for 1 year.NoteThe ASA 5506-X and ASA 5506W-X do not support time-based licenses.Time-Based License Activation Guidelines.You can install multiple time-based licenses, including multiple licenses for the same feature. The permanent activation key includes all licensed features in a singlekey. This license might be the Base License, to which you want to addmore licenses, or it might already have all of your licenses installed,depending on what you ordered and what your vendor installed for you.Related ConceptsPermanent LicenseYou can have one permanent activation key installed. This value encodes the serial number (an 11 character string) and the enabled features.Preinstalled LicenseBy default, your ASA ships with a license alreadyinstalled. It is represented by an activation key that is a 160-bit(5 32-bit words or 20 bytes) value.
