storm-control (Interface)
Use this command to configure the device to prevent storm attacks on a LAN.
There are three traffic types, broadcast, multicast, and unicast (DLF). Use the no
form of the command to disable the storm-control function.
storm-control {broadcast | multicast | unicast}
no storm-control {broadcast | multicast | unicast}
Default
Disabled (all storm types)
Command Mode

Usage Guideline
Only physical port interfaces are valid for this command.
Enter the "storm-control" command to enable Storm Control for a specific traffic
type on the interface.
All packets are passed in default without storm control enabled. After enabling
traffic storm control, if the storm-control action is to drop, then packets exceeding
the level will be dropped. If the storm-control action is set to shutdown, then the
interface will be shutdown whenever the packets exceed the threshold.
