Replacing a Controller on a Multi-Controller Network
The procedure to replace a controller within a multi-controller network varies, depending upon the role of that
controller, whether the network has a single master controller or a cluster of master Dell controllers, and whether or
not the controller has a backup.
NOTE: The following sections describe the steps to replace an existing controller. To add a new local controller to a network, or
permanently remove a local controller without replacing it, see "Viewing and Managing the Master or Local Switch Whitelists" on
page 88.
Replacing Controllers in a Single Master Network
Use the procedures in this section to replace a master or local controller in a network environment with a single
master controller.
Replacing a Local Controller
Use the following procedure to replace a local controller in a single-master network.
1. Disconnect the local controller from the network.
2. If you plan on moving the local controller to another location on the network, purge the campus AP whitelist on
the controller.
Access the command-line interface on the old local controller and issue the command whitelist-db cpsec
purge
or,
Access the local controller WebUI, navigate to Configuration>AP Installation>Campus AP Whitelist and click
Purge.
3. Once the campus AP whitelist has been purged, you must inform the master controller that the local controlleris
no longer available. .
NOTE: This step is very important; unused local controller entries in the local switch whitelist can significantly increase network
traffic and reduce controller memory resources.
Access the command-line interface on the master controller, and issue the command whitelist-db cpsec-
local-switch-list del mac-address <local-controller-mac>
-or -
Access the maser controller WebUI, navigate to the Configuration>Controller>Control Plane Security
