Default DSCP-to-Internal-Forwarding-Priority Mappings

Internal forwarding priority DSCP value
0 [lowest priority queue] 0–7
1 8–15
2 16–23
3 24–31
4 32–39
5 40–47
6 48–55
7 [highest priority queue] 56–63

DSCP values range from 0 through 63, whereas the internal forwarding priority values range from 0 through 7. Any DSCP value within a given range is mapped to the same internal forwarding priority value. For example, any DSCP value from 8 through 15 maps to priority 1.
