What Is A Cluster?

a single point of administration and lets you view the deployment of access points as a single
wireless network rather than a series of separate wireless devices.
6.3.1 What Is A Cluster?
A cluster is a group of access points which are coordinated as a single group via 9160 G2
Wireless Gateway administration. You can have multiple clusters on the same subnet if they
have different cluster “names”.
6.3.2 How Many APs Can A Cluster Support?
Currently, there is no hard limit on the number of access points in a cluster. Validation
testing has verified a dozen or more supported on the same subnet. You can include as many
APs as needed in a cluster at any one time.
6.3.3 What Kinds Of APs Can Cluster Together?
A single 9160 G2 Wireless Gateway can form a cluster with itself (a “cluster of one”) and
with other 9160 G2 Wireless Gateways. In order to be members of the same cluster, access
points must be:
•
Compatible devices as designated by the manufacturer (access points must have com-
patible design features).
• Of the same radio configuration (all one-radio APs or all two-radio APs).
• Of the same band configuration (all single-band APs or all dual-band APs).
• On the same LAN .
Having a mix of APs on the network does not adversely affect 9160 G2 Wireless Gateway
clustering in any way. However, it is helpful to understand the clustering behaviour for ad-
ministration purposes:
•
Access points joining the cluster must be named the same. For more information on
setting the cluster name, see page 60.
• Access points of other brands will not join the cluster. These APs should be adminis-
tered with their own associated Administration tools.
6.3.4 What is the Relationship of the Coordinator AP to Other Cluster Members?
Cluster configuration, sharing of configuration updates, and tracking of new APs joining or
leaving the group is managed by a
coordinator AP which is chosen from among the cluster
members. If a coordinator AP becomes unavailable, a new cluster member is assigned coor-
dinator responsibilities. This process is fully automated based on a ruleset that takes into
