Centralized mode

By default, the CN3000 functions as an access controller. This means that it controls
entry to the public access network via the public access interface. Customers must login
to gain access to the network.
In centralized mode, the CN3000 no longer functions as an access controller. Instead, it
automatically forwards all wireless traffic onto the Internet port. This is useful when a
remote site performs all access control functions. To safeguard the forwarded traffic you
can define a GRE tunnel (Network > GRE) and map all wireless traffic into it (Wireless
> WLAN profiles).
The following scenarios illustrate how to make use of centralized mode:
• "Scenario 3: Centralized authentication" on page 81
• "Scenario 4: Wholesaling with GRE" on page 84
