◆ Drop Precedence – Drop precedence used for controlling traffic congestion.
(Range: 0 - Green, 3 - Yellow, 1 - Red)
Web Interface
To map DSCP values to internal PHB/drop precedence:
1. Click Traffic, Priority, DSCP to DSCP.
2. Select Configure from the Action list.
3. Select a port.
4. Set the PHB and drop precedence for any DSCP value.
5. Click Apply.

The ingress DSCP is composed of ingress-dscp10 (most significant digit in the left column) and
ingress-dscp1 (least significant digit in the top row (in other words, ingress-dscp = ingress-dscp10 *
10 + ingress-dscp1); and the corresponding internal-dscp is shown at the intersecting cell in the
table.
The ingress DSCP is bitwise ANDed with the binary value 11 to determine the drop precedence. If the
resulting value is 10 binary, then the drop precedence is set to 0.
