• If a WAP device in a cluster loses connectivity, is dropped, later rejoins the cluster, and configuration
changes were made in the during the lost connectivity period, the changes are propagated to the device
when it rejoins. If there are configuration changes in both the disconnected device and the cluster, then
the device with the greatest number of changes and, secondarily, the most recent change, will be selected
to propagate its configuration to the cluster. (That is, if WAP1 has more changes, but WAP2 has the
most recent change, WAP1 is selected. If they have an equal number of changes, but WAP2 has the most
recent change, then WAP2 is selected.)
Operation of a Device Dropped From a Single Point Setup
When a WAP device that was previously a member of a cluster becomes disconnected from the cluster, the
following guidelines apply:
• The loss of contact with the cluster prevents the WAP device from receiving the latest operational
configuration settings. The disconnection results in a halt to proper seamless wireless service across the
production network.
• The WAP device continues to function with the wireless parameters that it last received from the cluster.
• The wireless clients associated with the non-clustered WAP device continue to associate with the device
with no interruption of the wireless connection. In other words, the loss of contact with the cluster does
not necessarily prevent the wireless clients associated with that WAP device from continued access to
network resources.
• If the loss of contact with the cluster is due to a physical or logical disconnection with the LAN
infrastructure, the network services out to the wireless clients may be impacted depending on the nature
of the failure.
