Figure 8 Line rate implementation
The token bucket mechanism limits traffic rate when accommodating bursts. It allows bursty traffic to be
transmitted if 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.
Configuring the line rate
The line rate of a physical interface specifies the maximum rate of incoming packets or outgoing packets.
Follow these steps to configure the line rate:
