Description
Use the traffic-limit command to activate an ACL and set traffic limitation to take
different actions for the packets within and beyond the preset traffic threshold.
Use the undo traffic-limit command to remove traffic limitation setting.
This command is only applicable to the packets which match the permitted rules in the
ACL.
It is required that CIR is less than or equal to PIR and CBS is less than or equal to EBS.
You are recommended to configure CBS and EBS to numbers that are 100 to 150 times
of CIR.
