WiMAX Device Configuration User’s Guide

Use this page to configure QoS settings on the WiMAX Device.

Click Network Setting > QoS to open this screen as shown next.

QoS Screen

This screen contains the following fields:

Use this page to enable the UPnP networking protocol on your WiMAX Device and allow easy 
network connectivity with other UPnP-compatible devices.

Enable RTSP ALG

Turns on the RTSP ALG to detect RTSP traffic and helps build RTSP sessions 
through the WiMAX Device’s NAT. 

Enable SIP ALG

Turns on the SIP ALG to detect SIP traffic and helps build SIP sessions through 
the WiMAX Device’s NAT.

SIP Port

If you are using a custom UDP port number (not 5060) for SIP traffic, enter it 
here.

Enable SIP ALG 
Set BSID

Check this box to add the base station ID to the outgoing SIP messages. Select 
this option only if the media server forwarding calls requires this information.

QoS

Interface

This displays the interface for the QoS rule. The IAD interface is for device 
management. Configure DiffServ Code Point (DSCP) and/or Priority marking 
based on which method is supported within your network. With DSCP you can 
use 64 (0-63) different markings, compared to 6 (1-6) with Priority marking.

DSCP 

Specify a DiffServ Code Point (DSCP) classification identification number (-1-63) 
to mark traffic that passes through this interface. Setting the DSCP to -1 
indicates marking is not enabled. A higher number indicates higher priority. The 
DSCP allows marked packets to receive specific per-hop treatment at DiffServ-
compliant network devices along the route based on the application types and 
traffic flow.

Priority

Select a priority level (1 to 6) to assign a priority to traffic that passes through 
this interface. A higher number indicates higher priority. Like DSCP, this marking 
is used to identify traffic for specific treatment. 

OK
