OcNOS SP : Quality of Service Guide : Quality of Service Configuration : Default QoS Mappings
Default QoS Mappings
If a user defined profile map is not created or applied to ingress or egress traffic, Qumran uses a default map to assign PCP, DSCP, EXP priority, and drop precedence values. The following tables describe the default QoS mapping values:
Ingress decode mapping table:
PCP, DEI-to-TC and DP table
DSCP-to-TC and DP table
EXP-to-TC and DP table
Egress encode mapping table:
TC and DP-to-PCP table
DSCP, DP-to-DSCP table
EXP encapsulation table
Table 9-2 lists the default PCP, DEI-to-TC, and DP mappings.
