Both inter-controller roaming and inter-subnet roaming require the controllers to be in the same mobility

group. See the next two sections for a description of mobility groups and instructions for configuring
them.

Overview of Mobility Groups

A set of controllers can be configured as a mobility group to allow seamless client roaming within a
group of controllers. By creating a mobility group, you can enable multiple controllers in a network to
dynamically share information and forward data traffic when inter-controller or inter-subnet roaming
occurs. Controllers can share the context and state of client devices and controller loading information.
With this information, the network can support inter-controller wireless LAN roaming and controller
redundancy.
Note Clients do not roam across mobility groups.
