When configuring TP,you can define the action of remarking the DSCP precedence for the packetsexceeding the traffic limit. Refer to Configuration Procedure of TP.z Through the traffic-priority command. Refer to the following description in thissection.1.5.1 Configuration Prerequisitesz ACL rules used for traffic identifying are defined. Refer to the ACL module in thismanual for defining ACL rules.z The type and value of the precedence that the packets matching ACL rules areremarked are specifiedz The ports which need this configuration are specified1.5.2 Configuration ProcedureFollow these steps to configure priority marking:To do… Use the command… RemarksEnter system view system-view —Enter Ethernet portviewinterface interface-typeinterface-number —Enter QoS view qos —traffic-priority { inbound |outbound } acl-rule[ system-index ] { { dscpdscp-value | ip-precedencepre-value } | local-precedencepre-value }*RequiredType-A LPUs supportthis command.Use ACL rules fortraffic identifying andassign a newprecedence for thepackets matching theACL rulestraffic-priority inbound acl-rule[ system-index ] { { dscpdscp-value | ip-precedencepre-value } | { cos cos |local-precedence pre-value } }*RequiredNon-type-A LPUssupport thiscommand.
