The queues match on the class of service (CoS) field. The device ensures that every CoS value from 0 to 7
maps to a queue for each queue type. Only one queue for a queue type can be assigned with a specific CoS
value. For more information about the system-defined queues, see
Class Maps, on page 15
DSCP-to-queue mapping is disabled by default. Use the hardware qos dscp-to-queue ingress command to
enable DSCP mapping on the modules. The table below describes the system-defined DSCP queuing class-maps
with the default DSCP values.
