FIGURE 134
Storm Control by Shutting Down a Port
The key elements of this diagram are the same as that described in the preceding diagram, except
that automatic release of the control response is not provided. When traffic control is applied, you
must manually re-enable the port.
Functional Limitations
Automatic storm control is a software level control function. Traffic storms can also be controlled at
the hardware level using Port Broadcast Control or Port Multicast Control (as described on
). However, only one of these control types can be applied to a port. Enabling automatic
storm control on a port will disable hardware-level storm control on that port.
Setting the ATC Timers
Use the Traffic > Auto Traffic Control (Configure Global) page to set the time at which to apply the
control response after ingress traffic has exceeded the upper threshold, and the time at which to
release the control response after ingress traffic has fallen beneath the lower threshold.

Command Usage
•
After the apply timer expires, the settings in the Traffic > Automatic Traffic Control (Configure
Interface) page are used to determine if a control action will be triggered (as configured under
the Action field) or a trap message sent (as configured under the Trap Storm Fire field).
•
The release timer only applies to a Rate Control response set in the Action field of the ATC
(Interface Configuration) page. When a port has been shut down by a control response, it must
be manually re-enabled using the Manual Control Release (see
Parameters
These parameters are displayed in the web interface:
•
Broadcast Apply Timer – The interval after the upper threshold has been exceeded at which to
apply the control response to broadcast storms. (Range: 1-300 seconds; Default: 300
seconds)
