Controller
In the Software-Defined Wireless Networking (SDWN) architecture the control plane is
centralized in a
Controller
, while the data plane remains distributed. Data plane elements
like the Gateway are configured with the IP address or fully qualified domain name
(FQDN) of the
Controller
.
Enter configuration mode
vyatta@vyatta:~$
configure
[edit]
Configure the Controller IP
or domain name
vyatta@vyatta#
set service anyfi gateway "1x-gw" controller
x.x.x.x

The Gateway should now have registered with the specified
Controller
and is ready to
accept incoming SDWN data plane tunnels from
radios
using the same
Controller
.
NOTE
The Controller is a controller in the Software-Defined Networking (SDN)
sense of the word, not in the typical corporate WLAN sense. For example the
Controller is not involved in IEEE 802.1X authentication and does not have access
to end-user credentials or encryption keys. Configuring the Gateway with a
Controller has no impact on system security.
UDP/IP Port Range
Gateways send and receive raw IEEE 802.11 frames over SDWN data plane UDP/IP
tunnels and will also communicate with the
Controller
over UDP/IP. The UDP port range
that a Gateway will use for such SDWN control and data plane communication is
configurable.
Enter configuration

vyatta@vyatta:~$

Configure the SDWN
UDP port range
vyatta@vyatta#
set service anyfi gateway "1x-gw" port-range
xxxx-xxxx

Configuration of the UDP port range used for SDWN data and control can facilitate
integration of the Gateway in environments with strict IP firewalling.
