Which type of roaming occurs when clients move between APs on the same WLC?

Intra-controller roaming refers to the situation where wireless clients move between access points (APs) that are managed by the same wireless LAN controller (WLC). This type of roaming is typically seamless and involves the WLC maintaining the same client session as the client moves from one AP to another, allowing users to maintain their connections without interruption.

During intra-controller roaming, decisions related to the transfer of client state information, such as authentication and session information, are handled internally by the WLC. As a result, this roaming type benefits from faster handoff times, as the controller can manage the necessary information without needing to communicate between different controllers.

In contrast, inter-controller roaming would involve clients moving between APs managed by different WLCs, which requires additional coordination and can introduce a delay as the client session must establish itself on a new controller. Other types of roaming like VLAN-based roaming are concerned with how VLANs are assigned or how traffic is managed but do not encapsulate the specific mechanism of movement between APs under the same WLC. CAPWAP roaming refers to the tunneling protocol used for communications between APs and their controllers but does not directly denote the type of roaming scenario being described.
