Start WLAN rollout to access points

After selecting the check box in the "Manage" field of all access points you want to use, you can launch the WLAN controller rollout and automatic frequency management with Start. The display now switches to a status screen indicating the WLAN controller's current activities:

Wireless LAN Controller->Wizard->Wireless LAN Controller Wizard

The configuration now is transfered sequentially to all access points. The configuration of an access point is finished and indicated with status managed after the best radio channel was found for it. When assigning radio channels, the WLAN controller ensures that only non-overlapping channels (e.g. 1, 6, 11) are assigned and that interference between the individual access points is kept to a minimum.

Managed access points are locked by the WLAN controller and all direct access to them is prohibited. An access point can only be locally configured after the WLAN controller released the access point.

After all access points are managed, the display changes once again and shows the final result:

Wireless LAN Controller->Wizard->Wireless LAN Controller Wizard

The configuration now needs to be saved on the WLAN controller device via the Save configuration button in the upper left. The access points themselves keep their current configuration in their volatile memory only and do not save it to their persistent memory. In the event of power failure, the configuration within the access points is lost and automatically re-loaded into the access point by the WLAN controller after power is restored. Keeping the configuration only in the volatile memory of the APs has the additional advantage that no sensitive access data (such as WLAN keys) can be compromised through theft of an access point installed at a public location.

After a power failure, all access points are re-initalised by the WLAN controller at once and radio management is not re-started, but the previously used channel is used instead. Thus recovery of WLAN infrastructure after power failure is much faster than the initial rollout.

Under Configure the Alert Service for WLAN surveillance, click Start to monitor your managed APs. You are taken to the External Reporting-> Alert Service -> Alert Recipient menu with the default setting Event = Managed AP offline . You can specify that you wish to be notified by e-mail if the Managed AP offline event occurs
