1.5 Configuring Priority Marking

Refer to
Priority marking can be implemented in the following ways:
Through TP (only non-type-A LPUs support this feature). When configuring TP,
you can define the action of remarking the DSCP precedence for the packets
exceeding the traffic limit. Refer to
Through the traffic-priority command. Refer to the following description in this
section.

1.5.1 Configuration Prerequisites

ACL rules used for traffic identifying are defined. Refer to the ACL module in this
manual for defining ACL rules.
The type and value of the precedence that the packets matching ACL rules are
remarked are specified
The ports which need this configuration are specified

1.5.2 Configuration Procedure

Follow these steps to configure priority marking:
Enter system view
Enter Ethernet port
view
Enter QoS view
Use ACL rules for
traffic identifying and
assign a new
precedence for the
packets matching the
ACL rules
