Always-On Licensing
Use of Always On Licensing requires that a valid license key be installed. Contact your Cisco account representative for
information on how to obtain a license.
Traditionally, transactional models have been based on registered subscriber sessions. In an “always-on” deployment
model, however, the bulk of user traffic is registered all of the time. Most of these registered subscriber sessions are idle
a majority of the time. Therefore, Always-On Licensing charges only for connected-active subscriber sessions.
