Using Diagnosis

The PT-7728 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

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 PT-7728’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:

y Output data stream

Select this option to monitor only those data packets being sent out

through PT-7728’s port.

y Bi-directional

Select this option to monitor data packets both coming into, and

being sent out through, PT-7728’s port.

STEP 2

Be sure to activate your settings before exiting.

• When using the Web Browser interface, activate by clicking on the Activate button.

• When using the Console utility, activate by first highlighting the Activate menu option, and

then press Enter. You should receive the Mirror port settings are now active! (Press any key

to continue) message.
