Automatic Traffic Control

Figure 138: Configuring Storm Control
Automatic Traffic Control
Use the Traffic > Congestion Control > Auto Traffic Control pages to configure
bounding thresholds for broadcast and multicast storms which can automatically
trigger rate limits or shut down a port.
Command Usage
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 139: 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.
