8 Clustering multiple M220s
Overview
The M220 supports AP clustering. A cluster provides a single point of administration and lets
you view, deploy, configure, and secure the wireless network as a single entity rather than a
series of separate wireless devices. When APs are clustered, you can also configure channel
planning, which helps to reduce radio interference and maximize bandwidth on the wireless
network.
The AP cluster is a dynamic, configuration-aware group of APs in the same wired subnet of a
network. Multiple clusters can exist within a subnet. Each cluster can have up to 10 members.
Shared settings in a cluster
When clustering is enabled, some configuration items are shared by the entire cluster, and
other items remain unique to each M220. In the management tool, an icon displays next to
items that are shared. When clustering is disabled, the icon does not display.
These items are shared when
clustering is enabled.
