6.3.9 Intra-Cluster Security
To ensure that the security of the cluster as a whole is equivalent to the security of a
single access point, communication of certain data between access points in a
cluster is done using Secure Sockets Layer (typically referred to as SSL) with
private key encryption.
Both the cluster configuration file and the user database are transmitted among
access points using SSL.
6.3.10 Auto-Synch Of Cluster Configuration
If you are making changes to the AP configuration that require a relatively large
amount of processing (such as adding several new users), you may encounter a
synchronization progress bar after clicking “Update” on any of the Administration
pages. The progress bar indicates that the system is busy performing an auto-synch
of the updated configuration to all APs in the cluster. The Administration Web pages
are not editable during the auto-synch.
Note that auto-synchronization always occurs during configuration updates that
affect the cluster, but the processing time is usually negligible. The auto-synch
progress bar is displayed only for longer-than-usual wait times.
6.4 Understanding Access Point Settings
The Access Points tab provides information about all access points in the cluster.
From this tab, you can view location descriptions, IP addresses, enable (activate) or
disable (deactivate) clustered access points, and remove access points from the clus-
ter. You can also modify the location description for an access point.
The IP address links provide a way to navigate to configuration settings and data on
an access point. Standalone access points (those which are not members of the clus-
ter) are not shown on this page.
