Chapter 3: Software Description
3.2.9.4 QoS Mode: DSCP
DSCP: Packets are prioritized using the DSCP (Differentiated Services Code Point)
value. The Differentiated Services Code Point (DSCP) is a six-bit field that is
contained within an IP (TCP or UDP) header. The six bits allow the DSCP field to
take any value in the range 0–63. When QoS Mode is set to DSCP, the DSCP
Configuration table is displayed, allowing you to map each of the DSCP values to
a hardware output queue (low, normal, medium or high). The default settings
map all DSCP values to the high priority egress queue. Users can use the Prioritize
Traffic drop-down list to quickly set the values in the DSCP Configuration table to
a common priority queue. Use Custom if you want to set each value individually.
