Chapter 1 Managing Feature Licenses
Information About Feature Licenses
For example:
1.
You have a 52-week Botnet Traffic Filter license installed on two units. The combined running
license allows a total duration of 104 weeks.
2.
The units operate as a failover unit/ASA cluster for 10 weeks, leaving 94 weeks on the combined
license (42 weeks on the primary/master, and 52 weeks on the secondary/slave).
3.
If the units lose communication (for example the primary/master unit fails), the secondary/slave unit
continues to use the combined license, and continues to count down from 94 weeks.
4.
The time-based license behavior depends on when communication is restored:
•
Within 30 days—The time elapsed is subtracted from the primary/master unit license. In this case,
communication is restored after 4 weeks. Therefore, 4 weeks are subtracted from the primary/master
license leaving 90 weeks combined (38 weeks on the primary, and 52 weeks on the secondary).
•
After 30 days—The time elapsed is subtracted from both units. In this case, communication is
restored after 6 weeks. Therefore, 6 weeks are subtracted from both the primary/master and
secondary/slave licenses, leaving 84 weeks combined (36 weeks on the primary/master, and 46
weeks on the secondary/slave).
Upgrading Failover Pairs
Because failover pairs do not require the same license on both units, you can apply new licenses to each
unit without any downtime. If you apply a permanent license that requires a reload (see
Table 1-19 on
page 1-36 ), then you can fail over to the other unit while you reload. If both units require reloading, then
you can reload them separately so you have no downtime.
No Payload Encryption Models
You can purchase some models with No Payload Encryption. For export to some countries, payload
encryption cannot be enabled on the Cisco ASA series. The ASA software senses a No Payload
Encryption model, and disables the following features:
•
Unified Communications
•
VPN
You can still install the Strong Encryption (3DES/AES) license for use with management connections.
For example, you can use ASDM HTTPS/SSL, SSHv2, Telnet and SNMPv3. You can also download the
dynamic database for the Botnet Traffic Filter (which uses SSL).
When you view the license (see the “Monitoring Licenses” section on page 1-40 ), VPN and Unified
Communications licenses will not be listed.
Licenses FAQ
Q.
Can I activate multiple time-based licenses, for example, AnyConnect Premium and Botnet Traffic
Filter?
A.
Yes. You can use one time-based license per feature at a time.
Q.
Can I “stack” time-based licenses so that when the time limit runs out, it will automatically use the
next license?
