Overview

A cluster is a group of two or more access points that have similar
configurations and are managed as a single unit. When you change a
parameter on one unit of a cluster, your change is automatically
communicated to the other units, which change the same parameter. This
can simplify the task of managing units that have nearly identical
configurations.

The parameters of the access points of a cluster are divided into shared
and non-shared parameters. Shared parameters have the same settings
on all the access points of the cluster. Changing the setting of a shared
parameter on one unit automatically changes the same parameter on the
other units. For instance, the MAC filter, which is used to control access by
wireless clients to the access point, is a shared parameter because your
changes to the feature on one access point are automatically sent to the
other access points in the same cluster.

In contrast, changes to non-shared parameters are not communicated to
the other members of the cluster. Consequently, the access points of the
cluster can have different settings for their non-shared parameters. To
configure these parameters, you have to establish individual management
sessions on the units. The IP address of an access point is an example of
an non-shared parameter because each unit must have a unique IP
address. There are also non-shared functions, such as viewing event
messages and statistics, because each unit is responsible for maintaining
its own event messages log and statistics table.

Table 11 lists the shared and non-shared features and functions of the
access points in a cluster.
