APs download theirco nfigurationsfrom a master controller.However, an AP or AP groupcan tunnel client traffic to
a local controller.To specify the controller to which an AP or AP group tunnels client traffic, you configuret heLMS
IP in the AP system profile on the master controller.
Configuration changestake effect o nlyafter yo u reboot the affected APs; this allows them to reassociate with the
localc ontroller.After rebooting, these AP s appear to the new local controller as local APs.

Moving to a Mu lti-Controller Environment
For a singleWLAN co nfiguration,the master controller is the controller which controls the RF andsecurity settings
of the WLAN. Additional Dell controllersto t hesame WLAN serve as local switches to the master controller.The
localc ontrolleroperates independently of the master controller and depends on the master controller only fori ts
security and RF settings. You configure the layer-2and layer-3 settings on the local controller independent of the
master controller.The local controllerneeds to have connectivity to the master controller at alltimes to ensure that
any changeson the master are propagated to the local controller.
Some of the common reasonst o move froma si ngleto a multi-controller-environment include:
lScalingto include a largercoverage area
lSetting up remote Access Points (APs)
lNetwork setup requiresAPs to be redistributed from a single controllerto multiple Dell controllers
