How do HP MSM products, which support the optimized WLAN architecture, forward client traffic
onto the wired network?

A.
The APs can forward traffic for the some VSCs directly onto the wired network, but forward
traffic tunneled or access-controlled VSCs to the controller.

B.
The controller always forwards traffic onto the wired network, thereby simplifying management
and improving security.

C.
While an individual AP must either forward all traffic locally or forward all traffic to the controller,
different APs can exhibit different behaviors based on the needs of the company.

D.
The APs always forward traffic directly onto the wired network, thereby optimizing the traffic
flow.

Optimized WLAN architectures
HP uses the optimized WLAN architecture—an architecture that capitalizes on thestrengths of the
centralized WLAN architecture while overcoming its limitations.
With the optimized WLAN architecture, you still have all the benefits of configuringand managing
APs, which might be deployed at several sites, from a centralizedcontroller. However, you also
have much more flexibility in how traffic is distributedonto the wired network and how
authentication and access control measures areapplied.
You can configure an optimized WLAN architecture to:
-Use APs to enforce user authentication to an external server and to bridge users’wireless traffic
directly onto the wired network
-Use the controller to enforce user authentication (to a local database or anexternal server), but
allow APs to forward authenticated users’ wireless trafficdirectly onto the wired network
-Use the controller to handle both users’ authentication and the forwarding of allwireless user traffic
onto the corporate LAN
These options are shown in the figure:
-Distributed forwarding
-Distributed forwarding with centralized authentication
-Centralized access control
As you will see when you begin implementing VSCs in the labs for this course, youcan configure
how traffic is handled for each VSC. That is, one VSC might beconfigured with centralized access
control, which means the AP forwards allauthentication and wireless users’ traffic to the controller.
For another VSC, the AP mayhandle authentication requests and forward traffic directly onto the
wired network.
For all architectures, management traffic flows between the controlled AP and thecontroller. How
the APs and controller handle user traffic, as well as traffic related toauthenticating users, relates
to the type of VSC.
