The VLAN ID must be the VLAN number on the home agent controller.
To view currently-configuredmobility domains in the CLI, use the show ip mobile domain command.
Makes urethat the ESSID to which the mobile client will connect supports IP mobility. You can disable IP mobility
for an ESSID in the virtual AP profile (IP mobility is enabled by default). If you disable IP mobility for a virtual AP,
any client that associates to the virtual AP will not have mobility service.
Joining a Mob ilityD omain
Assigning a controllert o a specific mobility domain is the key to defining the roaming areafor mobile clients. You
shouldtake extra care in planning your mobility domains, including surveying the user VLANs and Dell controllersto
which clients can roam, to ensure that there are no roaming holes.
All Dellcontrollers are initially part of the “default” mobility domain. If you are using the defaultmobilit y domain,
you do not need to specify this domai n as the active domain on a controller. However, once you assign a controller
to a user-defineddomai n,the “ default”mobility domain is no longer an active domain on the controller.
In the WebUI
1. N avigate to the Configuration >Advanced Services >IP Mobility page.
2. I n the Mobility Domain list, select the mobility domain.
3. Select the Act ive checkboxfor the domain.
4. Click A pply.
In the CLI
ip mobile active-domain <name>
To view the active domains in the CLI, use the show ip mobile active-domains command on the controller.
Example C onfiguration
The followingexample (Figure 152) configures a network in a campus with three buildings.A Dell controlleri n
each buildingprovides network connections for wireless users on severaldifferent user VLANs. To allow wireless users
to roam from buildingt o buildingwi thout interruptingongoing sessi ons, you configurea mobilit y domain that
includesall user VLANs on the three Dell controllers. Youc onfigurethe HAT on the master controller only
(controllerA in this example). On the localD ellcontrollers (Dell controllersB and C), you only need to enable
mobility.
