storm-control action (Interface)
This command configures the action type for the Storm Control function. It is only
used for two traffic types, broadcast and multicast. Use the no form of the
command to return to the default settings.
storm-control {broadcast | multicast} action {drop | shutdown}
no storm-control {broadcast | multicast} action
Default
action drop
Command Mode
Interface configuration
Usage Guideline
Only physical port interfaces are valid for this command.
All packets are passed by default. After enabling traffic storm control, if storm-
control action is drop, packets exceeding the level will be dropped. However if
the storm-control action is set to shutdown, then the interface will be shutdown
upon packets exceeding the level setting.
The Shutdown action is only available for broadcast and multicast storm control.
For unicast storm control, the software level is unable to identify unknown unicast
(DLF) storm events due to the hardware chip being unable support this function.
Therefore, if unknown unicast packets exceed the set level, they will always be
dropped.
Examples
This example shows how to configure Broadcast storm control action by setting a
shutdown action on interface eth3.1. In this situation, the threshold level is not
specified and the default threshold is 131072 PPS.
