Rate Limit Commands
This function allows the network manager to control the maximum rate
for traffic transmitted or received on an interface. Rate limiting is
configured on interfaces at the edge of a network to limit traffic 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.
Note: The “rate limit granularity” is multiplied by the “rate limit”
(page 4-160) to set the actual rate limit for an interface. Granularity
is a global setting that applies to Fast Ethernet or Gigabit Ethernet
interfaces.
