[Archive] [WLC] Limiting client sessions for each service-profile



Article ID: KB31381 KB Last Updated: 10 Oct 2020Version: 2.0

A WLA radio can be configured to allow only a certain number of active client sessions, after which it will refuse connections from additional clients. This can be done for each service-profile.

This article explains how to configure a limit on the number of active client sessions allowed for each service-profile.



Client sessions can be limited by configuring a CAC-session for the service-profile with the following command:

set service-profile profile-name cac-session <max-sessions>

The above command specifies the maximum number of active sessions that a radio can have when session-based call admission control (CAC) is enabled. When the radio reaches the maximum number of active sessions allowed, it will refuse connections from additional clients.


  • The default number of sessions allowed is 14.
  • Usage: This command applies only when the CAC mode is set to session. If the CAC mode is none, the maximum number of sessions can be changed, but the setting does not take effect until you change the CAC mode to session. To change the CAC mode, use the above set service-profile cac-mode command.

Example: The following command changes the maximum number of sessions for the radios used by the service profile, sp1, to 10:

WLC# set service-profile <sp1> cac-session 10
