Configuring Priority Marking
Refer to Priority Marking for information about marking packet priorities.
This feature is available only on the H3C S5100-EI series switches.
You can mark packet priorities in one of the following two ways:
z Through traffic policing
When configuring traffic policing, you can define the action of marking the 802.1p
precedence and DSCP values for packets exceeding the traffic specification. For detailed
information, refer to
Configuring Traffic Policing.
z Through the traffic-priority command
You can use the traffic-priority command to mark the 802.1p precedence and DSCP
values for the specific packets.
Configuration prerequisites
z The ACL rules used for traffic classification have been specified. Refer to the ACL
module of this manual for related information.
