broadcast - Specifies automatic storm control for broadcast traffic.

rate-control
- If a control response is triggered, the rate of ingress
traffic is limited based on the threshold configured by the auto-
traffic-control alarm-clear-threshold command.
shutdown
- If a control response is triggered, the port is
administratively disabled. A port disabled by automatic traffic
control can only be manually re-enabled.

Interface Configuration (Ethernet)
COMMAND USAGE
â—† When the upper threshold is exceeded and the apply timer expires, a
control response will be triggered based on this command.
â—† When the control response is set to rate limiting by this command, the
rate limits are determined by the auto-traffic-control alarm-clear-
threshold command.
â—† If the control response is to limit the rate of ingress traffic, it can be
automatically terminated once the traffic rate has fallen beneath the
lower threshold and the release timer has expired.
â—† If a port has been shut down by a control response, it will not be re-
enabled by automatic traffic control. It can only be manually re-enabled
using the auto-traffic-control control-release command.
EXAMPLE
This example sets the control response for broadcast traffic on port 1.
