About the Network Domain Feature 167
Figure 5 illustrates how user Bob, who is based at Sales Office C gets
connectivity and is placed in a VLAN when he visits the Corporate Office.
Figure 5 How a user connects to a remote VLAN in a Network Domain
In this example, Bob establishes connectivity as follows:
1 Bob connects to the wireless network at the Corporate Office. The WX
switch contacts the local Mobility Domain seed and finds that the VLAN
that Bob is configured to be on, VLAN Red, does not exist in the
Corporate Office Mobility Domain.
2 Unable to find VLAN Red in the local Mobility Domain, the WX switch
then contacts the local Network Domain seed. The Network Domain seed
contains a database of all the VLANs configured on all the members of
the Network Domain. (The Network Domain seed may or may not be the
same WX switch as the Mobility Domain seed.)
3 The Network Domain seed looks in its database and finds that VLAN Red
exists in the Mobility Domain at Sales Office C. The Network Domain seed
then responds with the IP address of the remote WX switch where VLAN
Red is configured.
