Once the traffic rate exceeds the upper threshold and the Apply Timer
expires, a trap message will be sent if configured by the Trap Storm
Fire attribute.
Alarm Clear Threshold – 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 Release Control
attribute. (Range: 1-255 kilo-packets per second; Default: 128 Kpps)
If rate limiting has been configured as a control response and Auto
Control Release is enabled, rate limiting 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 Manual Control Release.
Once the traffic rate falls beneath the lower threshold and the Release
Timer expires, a trap message will be sent if configured by the Trap
Storm Clear attribute.
