Create a QoS Policy
There are two types of QoS policies — input and output.
Input QoS policies regulate Layer 3 and Layer 2 ingress traffic. The regulation mechanisms for input QoS
policies are rate policing and setting priority values.
• Layer 3 — QoS input policies allow you to rate police and set a DSCP or dot1p value. In addition, you
can configure a drop precedence for incoming packets based on their DSCP value by using a DSCP
color map. For more information, see DSCP Color Maps.
• Layer 2 — QoS input policies allow you to rate police and set a dot1p value.
Output QoS policies regulate Layer 3 egress traffic. The regulation mechanisms for output QoS policies are
rate limiting, rate shaping, and WRED.
NOTE: When changing a "service-queue" configuration in a QoS policy map, all QoS rules are deleted and
re-added automatically to ensure that the order of the rules is maintained. As a result, the Matched
Packets value shown in the show qos statistics command is reset.
NOTE: To avoid issues misconfiguration causes, Dell Networking recommends configuring either DCBX
or Egress QoS features, but not both simultaneously. If you enable both DCBX and Egress QoS at the
same time, the DCBX configuration is applied and unexpected behavior occurs on the Egress QoS.
