Managing License Keys
License keys define capacity limits (number of allowed subscriber sessions) and available features on your
system. Adding new license keys allows you to increase capacity and add new features as your subscriber
base grows.
New System License Keys
New systems are delivered with no license keys installed. In most cases, you receive the license key in electronic
format (usually through e-mail).
When a system boots with no license key installed a default set of restricted session use and feature licenses
is installed. The following Exec Mode command lists the license information:
[local]
host_name
#
show license information
With no license key installed, the session use licenses for PDSN, HA, GGSN, and L2TP LNS are limited
to 10,000 sessions.
Important
Session Use and Feature Use Licenses
Session use and feature use licenses are software mechanisms that provide session limit controls and enable
special features within the system. These electronic licenses are stored in the system's configuration file that
is loaded as part of the system software each time the system is powered on or restarted.
•
Session use licenses limit the number of concurrent sessions that a system is capable of supporting per
service type and are acquired on an as-needed basis. This allows carriers to pay only for what they are
using and easily increase capacity as their subscriber base grows.
•
Feature use licenses enable specific features/functionality within the system and are distributed based
on the total number of sessions supported by the system.
