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 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
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.
