Configuring DSCP Port Marking
You can set the DSCP value for each class of traffic defined in a specified ingress policy map.
The default behavior of the device is to preserve the DSCP value or to trust DSCP. To make the port untrusted,
change the DSCP value. Unless you configure a QoS policy and attach that policy to specified interfaces, the
DSCP value is preserved.
Note • You can attach only one policy type qos map to each interface in each direction.
• The DSCP value is trust on the Layer 3 port of a Cisco NX-OS device.
