Access Points - 48
Cluster Size and Membership
The upper limit of a cluster is eight access points. The Cluster Web User Interface pages provide a visual
indicator of the number of access points in the current cluster and warn when the cluster has reached
capacity.
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 accomplished through 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.
Auto-Synchronization of Cluster Configuration
If you are making changes to the access point 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 Web User Interface pages. The progress bar indicates that the system is busy
performing an auto-synchronization of the updated configuration across all APs in the cluster. The Web
User Interface 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-synchronization progress bar is displayed only for longer-
than-usual wait times.
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 cluster. 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 cluster) are not shown on this page.
