auto-traffic-control This command enables automatic traffic control for broadcast or multicast storms.

broadcast - Specifies automatic storm control for broadcast traffic.
multicast - Specifies automatic storm control for multicast traffic.
Default Setting

Command Usage
◆ Automatic storm control can be enabled for either broadcast or multicast
traffic. It cannot be enabled for both of these traffic types at the same time.
◆ 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.
Example
This example enables automatic storm control for broadcast traffic on port 1.
