Configuring Rate Limits

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

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 3-108) to set the actual rate limit for an interface. Granularity is a global setting that applies to Fast Ethernet or Gigabit Ethernet interfaces.

Command Usage

•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.
