QoS Mode: DSCP
DSCP: Packets are prioritized using the DSCP (Differentiated Services Code Point) value. The
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.
User 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.
When the QoS Mode is set to DSCP, the DSCP Configuration table is displayed as shown
below. Enter the DSCP Value and Priority mapping in the fields on the bottom half.
