Managing Single Point Setup Across WAP Devices
Managing Single Point Setup Across Access Points
Single Point Setup creates a dynamic, configuration-aware cluster, or group, of WAP devices
in the same subnet of a network. A cluster supports a group of up to 16 configured WAP551
and WAP561 devices, but no other models in the same cluster.
Single Point Setup allows the management of more than one cluster in the same subnet or
network; however, they are managed as single independent entities. The table below shows
Single Point Setup wireless service limits.
A cluster can propagate configuration information, such as VAP settings, QoS queue
parameters, and radio parameters. When you configure Single Point Setup on a device,
settings from that device (whether they are manually set or set by default) are propagated to
other devices as they join the cluster. To form a cluster, make sure the following prerequisites
or conditions are met:
STEP 1
Plan your Single Point Setup cluster. Be sure the two or more WAP devices you want to cluster
are compatible with each other. For example, Cisco WAP551 devices can only cluster with
other Cisco WAP551 or WAP561 devices.
NOTE
It is strongly recommended to run the latest firmware version on all clustered
WAP devices. Firmware upgrades are not propagated to all WAP devices in a cluster;
you must upgrade each device independently.
STEP 2
Set up the WAP devices that will be clustered on the same IP subnet and verify that they are
interconnected and accessible across the switched LAN network.
STEP 3
Enable Single Point Setup on all WAP devices. See Access Points .
STEP 4
Verify that the WAP devices all reference the same Single Point Setup name. See Access
Points .
Single Point Setup Negotiation
Single Point Setup Negotiation
When a WAP device is enabled and configured for Single Point Setup, it begins sending
periodic advertisements every 10 seconds to announce its presence. If there are other WAP
devices that match the criteria for the cluster, arbitration begins to determine which WAP
device will distribute the master configuration to the rest of the members of the cluster.
The following rules apply to Single Point Setup cluster formation and arbitration:
