Working with controlled APs
Authentication of controlled APs
6-20
If authentication fails (for example, this is a new AP), and the Use the local authentication
list option is enabled, then the AP is added to the Default Group and flagged as requiring
authentication. The AP must then be manually authenticated by a manager using the
Controlled APs >> Overview > Discovered APs page. Once authenticated, the AP can be
managed.
Note APs remain visible in this list as long as they have been detected and authorized at least once.
If an AP is no longer part of the network then a manager must manually remove it.
Building the AP authentication list
The controller can retrieve authentication list entries from several sources: a RADIUS
account, a file, or using the set of locally configured APs. All entries are merged to create a
combined list.
The controller retrieves authentication list entries when:
The Authentication interval expires
Authenticate Now is selected
Save is selected
Each time the controller starts up.
Each time the authentication list entries are retrieved, all connected APs are checked against
it. If an AP MAC address is no longer listed, its connection is terminated.
Note Although the same RADIUS account can be shared between this option and the Public
access > Attributes page, it is recommended that a separate RADIUS account be created
for each option.
General settings
Authentication interval
Specifies the interval at which the controller retrieves authentication list entries from the
selected authentication sources. After the entries are retrieved all controlled APs are
evaluated against the new list.
Authenticate Now
Causes the controller to retrieve authentication list entries from all selected sources.
