Automatic Traffic Control Commands
16
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.
Syntax
auto-traffic-control {broadcast | multicast} alarm-fire-threshold threshold
no auto-traffic-control {broadcast | multicast} alarm-fire-threshold
broadcast - Specifies automatic storm control for broadcast traffic.
multicast - Specifies automatic storm control for multicast traffic.
threshold - The upper threshold for ingress traffic beyond which a storm control response
is triggered after the apply timer expires. (Range: 1-255 kilo-packets per second)
Default Setting
128 kilo-packets per second
Command Mode
Interface Configuration (Ethernet)
Command Usage
• Once the upper threshold is exceeded, a trap message may be sent if configured by the
snmp-server enable port-traps atc broadcast-alarm-fire command or snmp-server enable
port-traps atc multicast-alarm-fire command.
• After the upper threshold is exceeded, the control timer must first expire as configured by the
auto-traffic-control apply-timer command before a control response is triggered if configured by
the auto-traffic-control action command.
