storm-control
Configures the storm control functionality. This functionality sets the threshold of frames to
be flooded and received by a Switch. When a broadcast storm or another problem occurs,
the flooded frames exceeding the threshold are discarded. As a result, network load and
Switch load decrease.
The following are specifiable when storm control is used:
 A storm detection threshold (upper threshold), recovery-from-storm threshold, and
flow rate limit value (lower threshold) specified as a number of received frames
 Deactivating the target port or limiting the flow rate of received frames
 Monitoring time for canceling the flow rate limit
 Issuing SNMP traps or outputting an operation log data
