Automatic Traffic Control
– 232 –
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.
CLI REFERENCES
◆ "Automatic Traffic Control Commands" on page 773
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 109: 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
Manual Control Release (see page 235).
