WAN Backhaul Override Configuration
Profile Interface Override Configuration
A Wireless Wide Area Network (WWAN) card is a specialized network interface card that allows a
device to connect, transmit and receive data over a Cellular Wide Area Network. The RFS4000 and
RFS6000 each have a PCI Express card slot that supports 3G WWAN cards. The WWAN card uses
point to point protocol (PPP) to connect to the Internet Service Provider (ISP) and gain access to the
Internet. PPP is the protocol used for establishing internet links over dial-up modems, DSL
connections, and many other types of point-to-point communications. PPP packages your system’s
TCP/IP packets and forwards them to the serial device where they can be put on the network. PPP
is a full-duplex protocol that can be used on various physical media, including twisted pair or fiber
optic lines or satellite transmission. It uses a variation of High Speed Data Link Control (HDLC) for
packet encapsulation.
To define a WAN Backhaul configuration override:
1. Select Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service
platforms or Access Points.
2. Select a target Access Point (by double-clicking it) from amongst those displayed within the
Device Configuration screen.
Devices can also be selected directly from the Device Browser in the lower, left-hand, side of
the UI.
3. Select Profile Overrides from the Device menu to expand it into sub menu options.
4. Select Interface to expand its sub menu options.
5. Select WAN Backhaul.
Off Channel Scan list
for 2.4GHz Define a list of channels for off channel scans using the 2.4GHz Access Point radio. Restricting off
channel scans to specific channels frees bandwidth otherwise utilized for scanning across all the
channels in the 2.4GHz radio band.
Max Multicast Set the maximum number (from 0 - 100) of multicast/broadcast messages used to perform off channel
scanning. The default setting is four.
Scan Interval Set the interval (from 2 - 100 dtims) off channel scans occur. The default setting is 20dtims.
Sniffer Redirect Specify the IP address of the host to which captured off channel scan packets are redirected.
