Using Diagnosis
MOXA EtherDevice Switch provides two important tools for administrators to diagnose network
systems.
Mirror Port
The Mirror port function can be used to monitor data being transmitted through a specific port.
This is done by setting up another port (the mirror port) to receive the same data being transmitted
to, from, or both to and from, the port under observation. This allows the network administrator to
“sniff” the observed port and thus keep tabs on network activity.
Take the following steps to set up the Mirror Port function:
STEP 1
Configure MOXA EtherDevice Switch’s Mirror Port function from either the Console utility or
Web Browser interface. You will need to configure three settings:
Monitored Port Select the port number of the port whose network activity will be
monitored.
Mirror Port Select the port number of the port that will be used to monitor the
activity of the monitored port.
Watch Direction Select one of the following two watch direction options:
! Output data stream
Select this option to monitor only those data packets being sent out
through MOXA EtherDevice Switch’s port.
! Bi-directional
Select this option to monitor data packets both coming into, and
being sent out through, MOXA EtherDevice Switch’s port.
