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.
E
XAMPLE
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.
