Tracking Mobile Users

This section describes how you can view information about the status of mobile clients in the mobility domain.

Location-related information for users, such as roaming status, AP name, ESSIDExtended Service Set Identifier. ESSID refers to the ID used for identifying an extended service set., BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly., and physical type are consistent in both the home agent and foreign agent. The username, role, and authentication can be different on the home agent and foreign agent, as explained by the following:

L2 GREGeneric Routing Encapsulation. GRE is an IP encapsulation protocol that is used to transport packets over a network. tunnels are automatically established between managed devices in mobility domain at the time of boot up. Whenever a client connects to a managed device in a mobility domain, layer-2 authentication is performed and the station obtains the layer-2 (logon) role. When the client roams to other networks, layer-2 authentication is performed and the client obtains the layer-2 role. If layer-3 authentication is required, this authentication is performed on the client’s home agent only. The home agent obtains a new role for the client after layer-3 authentication; this new role appears in the user status on the home agent only. Even if reauthentication occurs after the station moves to a foreign agent, the display on the foreign agent still shows the layer-2 role for the user.

Listed below are the steps to view mobile client and user roaming status, mobile client roaming locations, and home agent discovery on association:
