This function allows the network manager to control the maximum rate 
for traffic transmitted or received on a port. Rate limiting is configured on 
ports at the edge of a network to limit traffic coming into or out of the 
network. Traffic that falls within the rate limit is transmitted, while packets 
that exceed the acceptable amount of traffic are dropped.

Rate limiting can be applied to individual ports or trunks. When an 
interface is configured with this feature, the traffic rate will be monitored 
by the hardware to verify conformity. Non-conforming traffic is dropped, 
conforming traffic is forwarded without any changes.

Rate limit granularity is an additional feature enabling the network manager 
greater control over traffic on the network. The “rate limit granularity” is 
multiplied by the “rate limit level” (page 3-113) to set the actual rate limit 
for an interface. Granularity is a global setting that applies to Fast Ethernet 
or Gigabit Ethernet interfaces.

•

For Fast Ethernet interfaces, the rate limit granularity can be set to 
512 Kbps, 1 Mbps, or 3.3 Mbps

•

For Gigabit Ethernet interfaces, the rate limit granularity is 33.3 Mbps.

granularity for Fast Ethernet and Gigabit Ethernet, and click apply.
