5.6.3 Port Tag Remaking
You can set QoS egress queues on a port such as classifying data and marking it according to
its priority and the policies. Packets will then travel across
the switch‟s internal paths carrying
their assigned QoS tag markers. At the egress port, these markers are read and used to
determine which queue each data packet is forwarded to. When the
traffic does not conform
to the conditions set in a policer command, you can remark the traffic.

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 transmission. With such
QoS functions, you can ensure low-latency for critical traffic. This page allows you to configure
DSCP settings for each port.
