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.
◆ If rate limiting has been configured as a control response, it will be
discontinued after the traffic rate has fallen beneath the lower threshold, and
the release timer has expired. Note that 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 clear threshold for automatic storm control for broadcast
traffic on port 1.
Console(config)#interface ethernet 1/1
Console(config-if)#auto-traffic-control broadcast alarm-clear-threshold 155
Console(config-if)#
auto-traffic-control
alarm-fire-threshold
This command sets the upper threshold for ingress traffic beyond which a storm
control response is triggered after the apply timer expires. Use the no form to
restore the default setting.
