Command Usage
This map is only used when the QoS mapping mode is set to “DSCP” by the qos
map trust-mode command, and the ingress packet type is IPv4.
Example
The ingress DSCP is composed of “d1” (most significant digit in the left column) and
“d2” (least significant digit in the top row (in other words, ingress DSCP = d1 * 10 +
d2); and the corresponding Internal DSCP and drop precedence is shown at the
intersecting cell in the table.
