Professional Access Point

Administrator Guide

Cluster

This section covers the Web User Interface Cluster items:

•“Access Points” on page 43

•“User Management” on page 53

•“Sessions” on page 59

•“Channel Management” on page 63

•“Wireless Neighborhood” on page 71

Access Points

The Professional Access Point shows current basic configuration settings for clustered access points (location, IP address, MAC address, status, and availability) and provides a way of navigating to the full configuration for specific APs if they are cluster members.

Standalone access points or those which are not members of this cluster do not show up in this listing. To configure standalone access points, you must discover (via the Detection Utility) or know the IP address of the access point and by using its IP address in a URL (http://IPAddressOfAccessPoint).

Note

The Professional Access Point is not designed for multiple, simultaneous configuration changes. If you have a network that includes multiple access points, and more than one administrator is logged on to the Web User Interface and making changes to the configuration, all access points in the cluster will stay synchronized but there is no guarantee that all configuration changes specified by multiple users will be applied.

The following topics are covered:

•Navigating to Access Points Management

•Understanding Clustering

•What is a Cluster?

•How Many APs Can a Cluster Support?

•What Kinds of APs Can Cluster?

•Which Settings are Shared as Part of the Cluster Configuration and Which Are Not?

•Cluster Mode

•Standalone Mode

•Cluster Formation
