4.10.2.3 IP DSCP Priority
The DSCP is six bits wide, allowing coding for up to 64 different forwarding behaviors. The DSCP retains backward
compatibility with the three precedence bits so that non-DSCP compliant, TOS-enabled devices, will not conflict with the DSCP
mapping. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding.
The DSCP default values are defined in the following table. Note that all the DSCP values that are not specified are mapped to
CoS queue 0.
IP DSCP Value CoS Queue
0, 8 0
10, 12, 14, 16, 18, 20, 22, 24 1
26, 28, 30, 32, 34, 36, 38, 40, 42 2
46, 48, 56 3
