Automatic Traffic Control Commands
– 466 –
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.
◆ 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.
