On the foreign network, the foreign agent delivers the tunneled data to the mobileclient.A mobility domain is a group of Dell PowerConnect W-Series controller among which a wireless user can roamwithout losing their IP address. Mobility domains are not tied with the master controller, thus it is possible for auser to roam between controller managed by different master controller as long as all of the controller belong tothe same mobility domain.You enable and configure mobility domains only on Dell PowerConnect W-Series controller. No additionalsoftware or configuration is required on wireless clients to allow roaming within the domain.Before configuring a mobility domain, you should determine the user VLAN(s) for which mobility is required. Forexample, you may want to allow employees to be able to roam from one subnetwork to another. All controllersthat support the VLANs into which employee users can be placed should be part of the same mobility domain.A controller can be part of multiple mobility domains, although Dell recommends that a controller belong to onlyone domain. The controllers in a mobility domain do not need to be managed by the same master controller.You configure a mobility domain on a master controller; the mobility domain information is pushed to all localcontroller that are managed by the same master controller. On each controller, you must specify the activedomain (the domain to which the controller belongs). If you do not specify the active domain, the controller willbe assigned to a predefined “default” domain.Although you configure a mobility domain on a master controller, the master controller does not need to be amember of the mobility domain. For example, you could set up a mobility domain that contains only localcontrollers; you still need to configure the mobility domain on the master controller that manages the localcontrollers. You can also configure a mobility domain that contains multiple master controllers; you need toconfigure the mobility domain on each master controller.You can enable or disable IP mobility in a virtual AP profile (IP mobility is enabled by default). When IP mobilityis enabled in a virtual AP profile, the ESSID that is configured for the virtual AP supports layer-3 mobility. If youdisable IP mobility for a virtual AP, any clients that associate to the virtual AP will not have mobility service.Advanced Services > IP MobilityNavigate to Advanced Services > IP Mobility page from the Dell PowerConnect W Configuration navigationpane. This page displays all currently configured profiles supporting IP Mobility, each group that uses each IPMobility profile, and the folder for each IP Mobility profile.Select Add to create a new IP Mobility profile, or click the pencil icon next to an existing profile to modifysettings on an existing profile. The Advanced Services > IP Mobility Profile Details page contains the followingfields, as described in Table 86:Table 85 Controllers in a Mobility DomainOn a master controller: On all controllers in the mobility domain:Configure the mobility domain, including the entries inthe home agent table (HAT). Enable mobility (disabled by default). Join a specified mobility domain (not required for “default” mobilitydomain).Table 86 Advanced Services > IP Mobility, Add/Edit Fields and DescriptionsField Default DescriptionGeneral SettingsFolder Top Set the folder with which the profile is associated.
