Automatic Traffic Control Commands
– 466 –
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.
Default Setting
rate-control
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.
