MSM7xx Controllers Configuration Guide v6.4.0

• Mobility Initiated at Home Interface: A request to setup a client connection at its home
network has been received.
• Mobile Terminated at Home Interface: A client connection at its home network has been
terminated. This normally happens only when the client has disconnected or the network
path to its connection point has been disrupted.
• Mobility Initiated at Client Interface: A request to setup a client connection at its connection
point (the AP where the client is associated) has been received.
• Mobility Terminated at Client Interface: A client connection at its connection point has been
terminated. This normally happens only when the client has disconnected or the network
path to its home network has been disrupted.
• Client roamed to another BSSID: A client for which a tunneling path has been established
has roamed to another AP. In this case, the tunneling path from its previous AP to its home
network is disconnected, and a tunneling path from its new AP to its home network is
established.
• Client updated VSC/VLAN/Network: A client for which a tunneling path has been
established has reconnected to a network and as a result has a new home network
assignment. In this case, the tunneling path to its previous home network is disconnected,
and a tunneling path to its new home network is established.
• No AP available to terminate client traffic: A home network terminated by an AP is not
currently available to egress the client traffic. In this case, data from the client will be
blocked until the home network (i.e., the AP) becomes available.
Scenario 1: Centralizing traffic on a controller
This scenario illustrates how to centralize the traffic from a VSC that is deployed on several APs
on different subnets. (On an MSM720, replace LAN port with Access network in the following
descriptions.)
How it works
In this scenario, a single controller manages several APs deployed on different subnets. The default
VSC (named HP) is assigned to each AP and is used to provide wireless services for users. All
traffic on this VSC is tunneled to the controller by MTM, where it is egressed onto the wired network.
To accomplish this, the egress network in the VSC binding is set to the network profile that is
assigned to the controller LAN port.
