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.
