Traffic Control 

On a computer network, packets such as Multicast packets and Broadcast packets continually flood the network as normal 
procedure. At times, this traffic may increase do to a malicious endstation on the network or a malfunctioning device, such as a 
faulty network card. Thus, switch throughput problems will arise and consequently affect the overall performance of the switch 
network. To help rectify this packet storm, the Switch will monitor and control the situation.  

The packet storm is monitored to determine if too many packets are flooding the network, based on the threshold level provided 
by the user. Once a packet storm has been detected, the Switch will drop packets coming into the Switch until the storm has 
subsided. This method can be utilized by selecting the

 

Drop

 

option of the

 

Action field in the window below. 

The Switch will also scan and monitor packets coming into the Switch by monitoring the Switch’s chip counter. This method is 
only viable for Broadcast and Multicast storms because the chip only has counters for these two types of packets. Once a storm 
has been detected (that is, once the packet threshold set below has been exceeded), the Switch will shutdown the port to all 
incoming traffic with the exception of STP BPDU packets, for a time period specified using the CountDown field.
