1.4.4 Marking Packet Priority

Refer to section
Marking packet priority can be implemented in the following two ways:
Through traffic policing
When configuring traffic policing, you can define the action of marking the DSCP
precedence for packets exceeding the traffic specification. Refer to section
Traffic Policing.
Through the traffic-priority command
You can use the traffic priority command to mark the IP precedence, 802.1p priority,
DSCP precedence, and local precedence of the packets.
I. Configuration prerequisites
The following items are defined or determined before the configuration:
The ACL rules used for traffic classification have been specified. Refer to the ACL
module of this manual for related information.
