Ports 

Note: You cannot mirror the destination port. 

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.  

 

Select the destination port from the Port to Mirror to drop-down list. Any port can be 
selected. The tick-box of the selected port will be cleared and disabled (see the Ports to Mirror 
section). 

Note:  Broadcast and Multicast packets are not mirrored since they are flooded to all ports 
anyway. 

There are four columns in this table. Two are titled Port and two are titled Mirroring Enabled. 

•  Port - The front-panel port number.  
•  Mirroring Enabled - This field is associated with the port-number that is displayed 

immediately on its left. Click on the tick-box to enable/disable Port Mirroring for the port.  

Note:  It will not be possible to select Mirroring Enabled for the destination port (the Port to 
Mirror to).
