• Entering the next-level policing (you can set multiple traffic policing levels each focused on specific
objects).
Line rate
The line rate of a physical interface specifies the maximum rate for forwarding packets (including critical
packets).
Line rate also uses token buckets for traffic control. With line rate configured on an interface, all packets
to be sent through the interface are first handled by the token bucket at line rate. If enough tokens are in
the token bucket, packets can be forwarded. Otherwise, packets are put into QoS queues for congestion
management. In this way, the traffic passing the physical interface is controlled.
Figure 8 Line rate implementation
The token bucket mechanism limits traffic rate when accommodating bursts. It allows bursty traffic to be
transmitted as long as enough tokens are available. If tokens are inadequate, packets cannot be
transmitted until efficient tokens are generated in the token bucket. It restricts the traffic rate to the rate for
generating tokens.
Line rate limits the total rate of all packets on a physical interface. It is easier to use than traffic policing
in controlling the total traffic rate on a physical interface.
