A Mobility Domain is a collection of WX switches that work together to 
support roaming users. One of the WX switches is defined as a seed 
device, which distributes information to the other WX switches defined in 
the Mobility Domain. 

A Mobility Domain allows users to roam geographically from one WX 
switch to another without losing network connectivity. Users connect as 
a member of a VLAN through their authorized identities. If the native 
VLAN for a user is not present on the WX to which the user connects, the 
WX creates a tunnel to that VLAN. 

A network plan can contain more than one Mobility Domain. Standalone 
WX switches and third-party APs do not need to be configured within a 
Mobility Domain. 

You use 3WXM to create a Mobility Domain and define its seed device 
and the other WX switches in the Mobility Domain. If you already have 
WX switches installed and configured, you can upload the configurations 
of the switches to 3WXM to have them included in a Mobility Domain.

For a client session to be considered a roaming session (and not a new 
session), the following criteria must be met:

„

The client associates or reassociates with a MAP in the Mobility 
Domain, and the client already has a session on a different MAP in the 
Mobility Domain. The existing session can be in one of two states:

„

Active—The normal state for a client that has left radio range 
without sending a request to disassociate.

„

Diassociated—The state of a client that has sent an 802.11 
disassociate frame, but has not roamed or aged out yet.
