Scenario 4: Assigning home networks on a per-user basis
This scenario illustrates how to assign home networks on a per-user basis using RADIUS attributes.
(On an MSM720, replace LAN port with Access network in the following descriptions.)
How it works
In this scenario, wireless services have been added to two wired networks. A single controller and
multiple APs are installed on each network. The two networks are connected with an L3 switch.
The following diagram provides an overview of the setup. (A single AP is shown on each network
for clarity).

Wireless clients receive their DHCP address from the controller on their network, or use a static IP
addressing scheme.
A single VSC is used in this scenario. It is configured with the Mobility traffic manager option
enabled. Home network assignment for users is done by setting RADIUS VLAN attributes which
map users to one of two network profiles:
Assigned toNetwork profile name
Net1
• Controller 1 LAN port
• All APs attached to network 10.0 use this as their home
network
Net2
• Controller 2 LAN port
• All APs attached to network 20.0 use this as their home
network
