MSM7xx Controllers Configuration Guide v6.4.0

The access control mechanism is used by the controller to manage user access to network resources.
Access control is applied on a per-VSC basis. When the Use Controller for Access control option
is enabled on a VSC, the configuration options on this page take effect with regards to client station
configuration, authentication, and authorization.
Use the checkbox in the title bar to globally enable or disable the access control mechanism:
• When enabled, the controller provides access control functionality which can then be configured
on a per-VSC basis.
• When disabled, the Public/Guest Network Access feature is disabled for all VSCs that are
configured to use access control.
The status light indicates the state of the authentication system.
• Green: Access control is working and authentication requests can be processed.
• Red: Access control cannot process authentication requests at this time.
User authentication
Allow access if authentication timed out
Enable this option to give users free access to the protected network if authentication services
configured for a VSC are unavailable. Once the authentication services are available again,
free user sessions remain active until the user logs out.
For example, if a user is connected to a VSC configured for HTML-based authentication using
a RADIUS server, and the RADIUS server is not responding, the user will be granted free access
to the network using the settings from the default user profile (Default AC).
NOTE: This feature does not work for users configured to use 802.1X or WPA when the
encryption keys are provided by the RADIUS server.
