What is the roaming process that occurs when a client decides to roam to a new access point (AP) or controller?
A. This is the sequence of events that occurs when a client roams to a new AP: • The client sends a reassociation request to the WLC through the LAP. • WLC sends the mobility message to other WLCs in the mobility group in order to find out with which WLC the client was previously associated. • The original WLC responds with information, such as the MAC address, IP address, QoS, Security context, etc. about the client through the mobility message. • The WLC updates its database with the provided client details; the client then goes through the reauthentication process, if necessary. The new LAP with which the client is currently associated is also updated along with other details in the database of the WLC. This way, the client IP address is retained across roams between WLCs, which helps to provide seamless roaming. For more information on roaming in a unified environment, refer to the Configuring Mobility Groups section of the Cisco Wireless LAN Controller Configuration Guide, Release
