1.5 Configuring Priority Marking
Refer to Priority Marking for the introduction to priority marking.
Priority marking can be implemented in the following ways:
z 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
Configuration Procedure of TP.
z Through the traffic-priority command. Refer to the following description in this
section.
1.5.1 Configuration Prerequisites
z ACL rules used for traffic identifying are defined. Refer to the ACL module in this
manual for defining ACL rules.
z The type and value of the precedence that the packets matching ACL rules are
remarked are specified
z The ports which need this configuration are specified
1.5.2 Configuration Procedure
Follow these steps to configure priority marking:
To do… Use the command… Remarks
Enter system view

Required
Type-A LPUs support
this command.
Use ACL rules for
traffic identifying and
assign a new
precedence for the
packets matching the
ACL rules
traffic-priority inbound acl-rule
[ system-index ] { { dscp
dscp-value | ip-precedence
pre-value } | { cos cos |
local-precedence pre-value } }*

Non-type-A LPUs
support this
command.
