For example, if you want to set the CAR bandwidth of 2 M for the traffic matching the
rule 0 on the switch, use the traffic-limit command to enable the CAR function on two
ports.
z If the inbound CAR function is enabled, the two ports provides guaranteed
bandwidth of 2 M for the traffic matching the rule 0 on each port.
z If the inbound CAR function is disabled, the two ports provide the total guaranteed
bandwidth of 2M for the traffic matching the rule 0 on the two ports.

Parameter
kbps: Specifies the limit rate to be measured in kbps.
target-rate: Total limit rate of all the packets sent by the port. If the kbps keyword is
specified, the rate is measured in kbps, in the range of 64 to 1,024,000 with the
granularity being 64. If the number you input is in the range of N*64 to (N+1)*64 (N is a
natural number), the switch will set the value to (N+1)*64 kbps automatically. If the
kbps keyword is not specified, the rate is in the range of 1 to 1,000 in mbps.
Description
Use the line-rate command to limit the rate of the packets on the port.
Use the undo line-rate command to cancel the rate limit configuration on the port.
