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 337: 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 an control
response can be automatically terminated after the release timer
Sends a trap when multicast traffic exceeds the
upper threshold for automatic storm control and
the apply timer expires
IC (Port)
Sends a trap when multicast traffic falls beneath
the lower threshold after a storm control
response has been triggered and the release
timer expires
IC (Port)
ATC Display Commands
Shows global configuration settings for
automatic storm control
PE
Shows interface configuration settings and
storm control status for the specified port
PE
*
Enabling automatic storm control on a port will disable hardware-level storm control
on the same port if configured by the
command.
