Storm Control 

Broadcast storms may occur when a device on your network is malfunctioning, or if 

application  programs  are  not  well  designed  or  properly  configured.  If  there  is  too 

much broadcast traffic on your network, performance can be severely degraded or 

everything can come to complete halt. 

You  can  protect  your  network  from  broadcast  storms  by  setting  a  threshold  for 

broadcast  traffic  for  each  port.  Any  broadcast  packets  exceeding  the  specified 

threshold will then be dropped. 

Storm Control Configuration 

There  are  three  type  of  traffic  which  can  be  rate  limited,  including  broadcast, 

multicast frame and Flooded Uncast Rate.
