Marking Packet Priority
Refer to section
for information about marking packet priority.
Marking packet priority can be implemented in the following two ways:
z
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
.
z
Through the traffic-priority command
