Configuring Traffic Classifiers

Procedure

1. Run system-view

   The system view is displayed.

2. Run traffic classifier classifier-name [ operator { and | or } ]

   The traffic classifier is defined and the traffic classifier view is displayed.

   classifier-name defined by users cannot be the one pre-defined by the system. The system-defined classifier, however, can be used when users define traffic policies. For details on traffic classification, see the HUAWEI NetEngine 8000 F Series Router Configuration Guide - QoS.

3. Configure the traffic classifier as required.
   • Run the if-match 8021p 8021p-value command to define a matching rule to classify traffic based on the 802.1p priority in a VLAN packet.
   • Run the if-match [ ipv6 ] acl { acl-number | name acl-name } command to define matching ACL rules.
   • Run the if-match [ ipv6 ] any command to define rules that match all packets.
   • Run the if-match destination-mac mac-address command to define a matching rule to classify traffic based on the destination MAC address.
   • Run the if-match ipv6 destination-address ipv6-address prefix-length command to define a matching rule to classify traffic based on the IPv6 destination address.
   • Run the if-match [ ipv6 ] dscp dscp-value command to define a matching rule to classify traffic based on the DSCP value.
   • Run the if-match mpls-exp exp-value command to define a matching rule to classify traffic based on the value of the MPLS EXP field.
   • Run the if-match ip-precedence ip-precedence command to define a matching rule to classify traffic based on IP precedence.
   • Run the if-match source-mac mac-address command to define a matching rule to classify traffic based on the source address.
   • Run the if-match tcp syn-flag { tcpflag-value [ mask tcpflag-mask ] | bit-match { established | fin | syn | rst |psh | ack | urg | ece | cwr | ns } } command to define a matching rule to classify traffic based on the IPv4 TCP flag value.
   • To define a rule to match traffic based on the IPv6 TCP flag, run the if-match ipv6 tcp syn-flag { tcpflag-value [ mask tcpflag-mask ] | bit-match { established | fin | syn | rst | psh | ack | urg } } command.

   You can select one or several matching rules in step 3 as required.

4. Run commit

   The configuration is committed.
