A client roams between APs on different floors joined to the same WLC in local mode; APs are in different AP groups with different IPs but the client VLAN is unchanged. What type of roam is this?

This is an intra-controller roam because the client remains associated with the same Wireless LAN Controller (WLC), even though it moves between different Access Points (APs) and AP groups. The WLC manages the client's mobility within its domain. An inter-controller roam would occur if the client moved to an AP joined to a different WLC. While the APs are in different AP groups and have different IPs, the key factor for this classification is the WLC. The client VLAN remaining unchanged supports the intra-controller classification, as there's no IP address change for the client, thus it's not an inter-subnet roam.
