Group/Cluster Type
Cisco WAP581
A cluster can propagate configuration information, such as VAP settings, the QoS queue parameters, and the
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 that two or more WAP devices that you want to cluster are the same model.
For example, Cisco WAP581 devices can only cluster with other Cisco WAP581 devices.
It is strongly recommended to run the same firmware version on all clustered WAP devices. Firmware can be

upgraded from the Dominant AP (Cluster Controller). See
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
Step 4
Verify that all WAP devices reference the same Single Point Setup name. See
Single Point Setup Negotiation
When a AP 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:
• For existing Single Point Setup clusters, whenever the administrator updates the configuration of any
• When two separate Single Point Setup clusters join into a single cluster, then the latest modified cluster
• If a WAP device in a cluster does not receive advertisements from a WAP device for more than 60
• If a WAP device in Single Point Setup mode loses connectivity, it is not immediately dropped from the

cluster. If it regains connectivity and rejoins the cluster without having been dropped, and configuration
changes were made to that device during the lost connectivity period, the changes are propagated to the
other cluster members when connectivity resumes.
