A Network Domain is a group of geographically dispersed Mobility 
Domains that share information over a WAN link. This shared information 
allows a user configured in one Mobility Domain to establish connectivity 
on a WX switch in a remote Mobility Domain. The WX switch forwards 
the user traffic by creating a VLAN tunnel to a WX switch in the remote 
Mobility Domain.
About the Network 
Domain Feature
A Network Domain allows functionality found in Mobility Domains to be 
extended over a multiple-site installation. A user configured to be on a 
VLAN at his or her home site can travel to a remote site, connect to the 
network, and be placed in his or her native VLAN. To do this, the WX 
switch that the user accesses forms a tunnel to a WX switch at the user’s 
home site. 
Figure 4 illustrates a sample Network Domain configuration consisting of 
Mobility Domains at six sites connected over a WAN link.
