Port Mirroring

The Port mirroring is a method for monitoring traffic in switched networks. Traffic through ports can be monitored by one specific port which means traffic goes in or out monitored (source) ports will be duplicated into mirroring (destination) port.

Destination Port: There is only one port can be selected to be the destination (mirroring) port for

 

monitoring both RX and TX traffic which come from the source port. Or, use one of two ports for

 

monitoring RX traffic only and the other one for TX traffic only. The user can connect the mirroring port

to LAN analyzer or Netxray.

Source Port: The ports that the user wants to monitor. All monitored port traffic will be copied to

 

mirroring (destination) port. The user can select multiple source ports by ticking the RX or TX

 

checkboxes to be monitored.

And then, click
