Console(config)#interface ethernet 1/1
Console(config-if)#auto-traffic-control broadcast
Console(config-if)#
auto-traffic-control
action
This command sets the control action to limit ingress traffic or shut down the
offending port. Use the no form to restore the default setting.
Syntax
auto-traffic-control {broadcast | multicast} action {rate-control | shutdown}
no auto-traffic-control {broadcast | multicast} action
broadcast - Specifies automatic storm control for broadcast traffic.
multicast - Specifies automatic storm control for multicast 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.

Command Mode
Interface Configuration (Ethernet)
Command Usage
◆ When the upper threshold is exceeded and the apply timer expires, a control
response will be triggered based on this command.
◆ 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.
◆ 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.
◆ 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.
