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.
