5.6.4 Port DSCP
DSCP (Differentiated Services Code Point) is a measure of QoS. It
can classify data packets
by using the 6-bit DS field in the IP header so you can manage each traffic class differently and
efficiently, thereby achieving optimized use of network bandwidth. DSCP-enabled routers on
the network will read the DSCP value of the data packet and put the packet into different
queues before transmission, such as high priority and most efficient transmis sion. With such
QoS functions, you can ensure low-latency for critical traffic. This page allows you to configure
DSCP settings for each port.
