[Command] traffic-behavior traffic_behavior_Name no traffic behavior
[Purpose] Create a traffic behavior and go to the Traffic behavior view, or go to the existing Traffic behavior view, or bind the traffic behavior to interface
[Purpose] traffic-behavior-name traffic behavior name
[View] System view, Interface view
[Use Cases]
sonic# configure terminal
sonic(config)# traffic-behavior test
sonic(config-traffic-behavior-test)#car {sr-tcm|tr-tcm} meter-type {bytes|packets}
[Command] car {sr-tcm|tr-tcm} [meter-type {bytes|packets}] [cir CIR_value ] [cbs CBS_value ] [pir PIR_value ] [pbs PBS_value ] [yellow-packet-action {DROP|FORWARD|REMARK}] [red-packet-action {DROP|FORWARD|REMARK}] [remark-dot1p Dot1p_value ] [remark-dscp Dscp_value ] [remark-tc Tc_value ]
[Purpose] Create a CAR template to bind to traffic behavior
[Parameter]
Parameter | Description |
|---|---|
sr-tcm | Single bucket single speed mode, this mode only requires the configuration of cir and cbs |
tr-tcm | Double buckets and double speed mode |
meter-type {bytes|packets} | If meter-type mode is bytes：cir, pir in kBps, cbs, pbs in byteIf meter-type mode is packets：cir, pir in Kpps, cbs, pbs in packetDefault mode is bytes |
CIR_value | Specifies the committed information rate (CIR), which is the allowed rate at which traffic can pass through |
CBS_value | Specifies the committed burst size (CBS), which is the average volume of burst traffic that can pass through an interface. |
PIR_value | Specifies the peak information rate (PIR), which is the maximum rate at which traffic can pass through. |
PBS_value | Specifies the peak burst size (PBS), which is the maximum volume of burst traffic that can pass through an interface. |
[View] Traffic behavior view
[Notes] When the burst size of the message < cbs value, the message is marked as green When cbs value < burst size < pbs value, the message is marked yellow When burst size > pbs value, the message is marked as red no car This command removes the CAR template
[Use Cases]
sonic# configure terminal
sonic(config)# traffic-behavior test
sonic(config-traffic-behavior-test)# car sr-tcm meter-type PACKETS cir 1000000traffic-behavior bind
[Command] traffic-behavior bind policer_name no traffic-behavior bind
[Purpose] Bind traffic behavior to the interface
[View] Interface view
[Use Cases]
sonic(config)# interface ethernet 1
sonic(config-if-1)# traffic-behavior bind test1port-shaper enable
[Command] port-shaper enable pir pbs no port-shaper enable
[Purpose] Enable the traffic shaping function on the interface for rate limiting.
[Parameter]
Parameter | Description |
|---|---|
pir | Configure the maximum allowed peak rate. Range: 55–4294967295. Unit: kbit/s |
pbs | Configure the maximum allowed burst size. Range: 4096–16777215. Unit: byte |
[View] Interface View
[User Scenario] Config traffic shaping to the interface. Traffic in the outbound direction from this interface will be rate-limited according to the user configuration.
[Use Cases]
sonic(config)# interface ethernet 1
sonic(config-if-1)# port-shaper enable 10000 128000
