Configuring a Traffic Behavior

Procedure

1. Run system-view

   The system view is displayed.

2. Run traffic behavior behavior-name

   A traffic behavior is created and the traffic behavior view is displayed, or the view of an existing traffic behavior is displayed.

3. Define actions in the traffic behavior. You can configure multiple non-conflicting actions in a traffic behavior.

   Action	Command
   Packet filtering	deny | permit
   Configure a QoS group that packets belong to	remark qos-group qos-group-value
   Priority re-marking by MQC	remark 8021p 8021p-value remark cvlan-8021p 8021p-value remark dscp { dscp-name | dscp-value } remark mpls-exp exp-value (AR1200&AR2200&AR3200&AR3600 series) remark fr-de fr-de-value remark local-precedence local-precedence-value NOTE: If a traffic behavior contains remark 8021p, remark mpls-exp, or remark dscp, but not remark local-precedence, the device marks the local priority of packets with 0.
   Traffic policing by MQC	car cir { cir-value | pct cir-percentage } [ pir { pir-value | pct pir-percentage } ] [ cbs cbs-value pbs pbs-value ] [ share ] [ mode { color-blind | color-aware } ] [ green { discard | pass [ remark-8021p 8021p-value | remark-dscp dscp-value | remark-mpls-exp exp-value ] } ] [ yellow { discard | pass [ remark-8021p 8021p-value | remark-dscp dscp-value | remark-mpls-exp exp-value ] } ] [ red { discard | pass [ remark-8021p 8021p-value | remark-dscp dscp-value | remark-mpls-exp exp-value ] } ] NOTE: The AR100&AR120&AR150&AR160&AR200 series do not support remark-mpls-exp exp-value.
   Traffic shaping by MQC	gts cir { cir-value [ cbs cbs-value ] | pct pct-value } [ queue-length queue-length ]
   Adaptive traffic shaping by MQC	gts adaptation-profile adaptation-profile-name
   Congestion management by MQC	queue af bandwidth { bandwidth | [ remaining ] pct percentage } queue ef bandwidth { bandwidth [ cbs cbs-value ] | pct percentage [ cbs cbs-value ] } queue llq bandwidth { bandwidth [ cbs cbs-value ] | pct percentage [ cbs cbs-value ] } queue wfq [ queue-number total-queue-number ] queue-length { bytes bytes-value | packets packets-value }*
   Congestion avoidance by MQC	drop-profile drop-profile-name
   Sampling of NetStream statistics by MQC	ip netstream sampler { fix-packets packet-interval | fix-time time-interval | random-packets packet-interval | random-time time-interval } { multicast | rpf-failure | unicast }* NOTE: The device does not support sampling of NetStream statistics for IPv6 and MPLS packets, so traffic classification rules cannot contain IPv6 or MPLS. Layer 2 VE interfaces do not support this function.
   Unicast PBR	redirect ip-nexthop ip-address [ vpn-instance vpn-instance-name ] [ track { nqa admin-name test-name | ip-route ip-address { mask | mask-length } | interface interface-type interface-number } ] [ post-nat ] [ discard ] [ sfc-nsh spi spi-index si si-index ] NOTE: If DSCP priority matching is configured in a traffic policy, the SAE220 (WSIC) and SAE550 (XSIC) cards do not support redirect ip-nexthop ip-address post-nat. redirect ipv6-nexthop ipv6-address [ track { nqa nqa-admin nqa-name | ipv6-route ipv6–address mask-length } ] [ discard ] redirect interface interface-type interface-number [ track { nqa admin-name test-name | ip-route ip-address { mask | mask-length } [ weak ] | ipv6-route ipv6-address mask-length } ] [ discard ] redirect vpn-instance vpn-instance-name NOTE: Layer 2 VE interfaces do not support this function. redirect backup-nexthop ip-address [ vpn-instance vpn-instance-name ]
   Sub traffic policy binding	traffic-policy policy-name
   Traffic statistics	statistic enable
   Configure MQC to implement URL filtering	url-filter-profile profile-name

   When an interface is added to a network bridge, the traffic behavior that is configured on the interface in the inbound direction can only define the following actions:

   • Re-marking the 802.1p priority in VLAN packets.
   • Configuring MQC to implement traffic policing.
   • Traffic statistics.

4. Run quit

   Exit from the traffic behavior view.
