Rate Limit Commands
This function allows the network manager to control the maximum rate
for traffic received on an interface. Rate limiting is configured on interfaces
at the edge of a network to limit traffic into the network. 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.
rate-limit
Use this command to define the rate limit level for a specific interface. Use
this command without specifying a rate to restore the default rate limit
level. Use the no form to restore the default status of disabled.
