Maximum User Sessions
For optimal performance, you can limit the number of concurrent users accessing the network resources.
ACS 5.3 imposes limits on the number of concurrent service sessions per user.
The limits are set in several different ways. You can set the limits at user level or at group level.
Depending upon the maximum user session configurations, the session count is applied on the user.
Note To make the maximum sessions work for the user access, the administrator should configure the
RADIUS accounting.
Note To make the maximum sessions work for the device management, the administrator should configure the
T+ session authorization and accounting.
