SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual 

Quality of Service (QoS) refers to a collection of techniques for identifying data whose 
delivery across the network is time sensitive, and managing its delivery through both 
bandwidth allocation and prioritization schemes 

Using the QoS Settings menu, you can enable the Gateway’s QoS module to provide 
guarantees on the ability of the network to deliver predictable results. To access the QoS 
menu, click QOS in the menu bar. Figure 30 shows an example of the menu.  

By default, QoS is enabled. To enable the Gateway’s QoS module, check Enable QOS 
Module and click Apply. To disable the Gateway’s QoS module, uncheck Enable QOS 
Module and click Apply. 

If you enable the Gateway’s QoS module, the following submenus appear under QOS in the 
menu bar: 

y 

Port - lets you configure the priority queue to which the switch port is mapped. See page 
64. 

y 

COS - lets you define four queues to which the CoS is mapped. See page 65. 

y 

DSCP - lets you define the QoS class queue to which the customized DSCP is mapped. 
See page 67. 

y 

Queue - lets you specify whether QoS behavior runs with strict or weighted priority. See 
page 69. 

y 

DSCP Remarking - lets you define the DSCP remarking action and mode. See page 71.
