Figure 422: 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 the switchport
packet-rate command. 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.
Threshold Commands
auto-traffic-control
apply-timer
This command sets the time at which to apply the control response after
ingress traffic has exceeded the upper threshold. Use the no form to
restore the default setting.
