Dscp Based Qos Menu - SMC Networks SMCD3GN2 User Manual

DSCP Based QoS Menu

The DSCP Based QoS menu lets you classify and prioritize traffic using DSCP tags. DSCP
allows the Gateway to determine how traffic classes should be prioritized. Using the DSCP
Based QoS menu, you can use DSCP to provide different levels of service to conforming
and non-conforming traffic by appropriately selecting the DSCP values in this menu. The
Gateway uses the Hierarchical Token Bucket queuing algorithm, which divides the 64
possible DSCP code values into 8 queues.
Table 7 shows the actual queuing.

submenu in the menu bar. Figure 26 shows an example of the menu.
Note: The DSCP submenu is not available in the menu bar if Enable QOS Module is not
checked in the QoS Settings menu (see page 39).
