Chapter 1 Managing Feature Licenses
Shared AnyConnect Premium Licenses
A shared license lets you purchase a large number of AnyConnect Premium sessions and share the
sessions as needed among a group of ASAs by configuring one of the ASAs as a shared licensing server,
and the rest as shared licensing participants. This section describes how a shared license works and
includes the following topics:

Decide which ASA should be the shared licensing server, and purchase the shared licensing server
license using that device serial number.
Decide which ASAs should be shared licensing participants, including the shared licensing backup
server, and obtain a shared licensing participant license for each device, using each device serial
number.
(Optional) Designate a second ASA as a shared licensing backup server. You can only specify one
backup server.
Note
The shared licensing backup server only needs a participant license.
Configure a shared secret on the shared licensing server; any participants with the shared secret can
use the shared license.
When you configure the ASA as a participant, it registers with the shared licensing server by sending
information about itself, including the local license and model information.
Note
The participant needs to be able to communicate with the server over the IP network; it does
not have to be on the same subnet.
The shared licensing server responds with information about how often the participant should poll
the server.
When a participant uses up the sessions of the local license, it sends a request to the shared licensing
server for additional sessions in 50-session increments.
The shared licensing server responds with a shared license. The total sessions used by a participant
cannot exceed the maximum sessions for the platform model.
Note
The shared licensing server can also participate in the shared license pool. It does not need
a participant license as well as the server license to participate.
