groups can also keep the network from unnecessary traffic by restricting the packet destination. 
The same setting is applied to all the ports on the switch. 

•  Type – List the type of traffic which can be rate limited, including ICMP, learn frames, 

broadcast, multicast and flooded unicast frames. 

•  Enable Storm Control – Click the check box to enable storm control for the specific 

frame type. 

•  Rate(number of frames per second) – The Rate field is set by a single drop-down list. The 

same threshold is applied to every port on the switch. When the threshold is exceeded, 
packets are dropped, irrespective of the flow-control settings.  

 
There are three main buttons associated with this page:  
 

•  HELP - Displays this text.  
•  APPLY - Updates the switch configuration. No changes are made to the configuration 

until this button is pressed.  

•  CANCEL - All changes made to the page are discarded and the switch configuration 

remains unchanged.  

 

 
This page allows you to copy (mirror) incoming packets on multiple ports to a single port. This 
can be useful for diagnosing problems. The page is split into two sections:  
 

•  Port to Mirror to - Choose the destination port. All the mirrored packets will be sent to 

the selected port.  

•  Ports to Mirror - The front-panel port number.
