Automatic Traffic Control Commands

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.

Example
This example sets the control response for broadcast traffic on port 1.

Console(config)#interface ethernet 1/1

Console(config-if)#auto-traffic-control broadcast action shutdown

Console(config-if)#

auto-traffic-control alarm-clear-threshold

This command sets the lower threshold for ingress traffic beneath which a control response for rate
limiting will be released after the Release Timer expires, if so configured by the

auto-traffic-control

auto-control-release

command. Use the no form to restore the default setting.

Syntax

auto-traffic-control {broadcast | multicast} alarm-clear-threshold threshold

no auto-traffic-control {broadcast | multicast} alarm-clear-threshold

broadcast - Specifies automatic storm control for broadcast traffic.

multicast - Specifies automatic storm control for multicast traffic.

threshold - The lower threshold for ingress traffic beneath which a cleared storm control
trap is sent. (Range: 1-255 kilo-packets per second)

Default Setting
128 kilo-packets per second

Command Mode
Interface Configuration (Ethernet)

Command Usage

Once the traffic rate falls beneath the lower threshold, a trap message may be sent if
configured by the

snmp-server enable port-traps atc broadcast-alarm-clear

command or

snmp-server enable port-traps atc multicast-alarm-clear

command.
