Automatic Traffic Control Commands

Usage Guidelines
ATC includes storm control for broadcast or multicast traffic. The control response
for either of these traffic types is the same, as shown in the following diagrams.
Figure 1: Storm Control by Limiting the Traffic Rate
The key elements of this diagram are described below:
◆ Alarm Fire Threshold – The highest acceptable traffic rate. When ingress traffic
exceeds the threshold, ATC sends a Storm Alarm Fire Trap and logs it.
◆ When traffic exceeds the alarm fire threshold and the apply timer expires, a
traffic control response is applied, and a Traffic Control Apply Trap is sent and
logged.
◆ Alarm Clear Threshold – The lower threshold beneath which a control response
can be automatically terminated after the release timer expires. When ingress
traffic falls below this threshold, ATC sends a Storm Alarm Clear Trap and logs it.
◆ When traffic falls below the alarm clear threshold after the release timer
expires, traffic control (for rate limiting) will be stopped and a Traffic Control
Release Trap sent and logged. Note that if the control action has shut down a
port, it can only be manually re-enabled using the auto-traffic-control control-
release command).
◆ The traffic control response of rate limiting can be released automatically or
manually. The control response of shutting down a port can only be released
manually.
