QoS Configuration 191
The system provides default mapping tables.
Configuring traffic parameters (optional)
Use the following command to set the traffic parameters required before
configuring traffic policing on service processor cards.

CAUTION: This operation is not required for configuring traffic policing on
common cards.
Perform the following configuration in system view.
Configuring traffic policing
The purpose of this configuration task is to implement traffic policing on
ACL-matched data streams, and then take normal actions on data streams within
the traffic limit and take other actions (discarding packets, for example) on those
exceeding the limit.
For interface cards, perform the following configurations in Ethernet port view.
Restore the default values of the DSCP +
