Using Controller Settings to Manage Switch Groups
Controller allows you to create switch groups, similar to AP zones. Switches connecting to controller can be placed in one of these logical groups for better manageability. A Staging or Default Group is created by the controller automatically. All switches are placed in this group when they initially joining the controller. You have the option to create additional groups.
Using registration rules, you can specify which group the switch should be placed into. Refer to Creating Switch Groups and Creating Switch Registration Rules for additional information.
