Abstract: Techniques are provided for allowing a client, initially associated with a home wireless switch and having a client IP address from within a first subnet, to layer 3 roam from the home wireless switch to a visited wireless switch configured to support a second subnet. These techniques can be implemented, for example, in a wireless local area network.

Abstract: Techniques are provided for creating an active client list that can be distributed to a plurality of wireless switches. The wireless switches are located in a wireless local area network comprising a registration server, a plurality of active clients, and the plurality of wireless switches. Registration information associated with each of the active clients is communicated to the wireless switches that support those active clients. The registration information associated with each of the active clients from the wireless switches is communicated over an IP tunnel to the registration server. An active client list can then be created using the registration information for each active client. The active client list comprises a record for each active client in the wireless local area network.

Abstract: A method and apparatus for communicating between devices is described. In one embodiment, the method comprises running two or more instances of a switch MAC sublayer on a switch and managing the two or more instances of the switch MAC sublayer as multiple logical access points inside the switch.
