PT-7728 User’s Manual Featured Functions
3-71
The Mirror port function can be used to monitor data being transmitted through specific ports.
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 ports under observation. This allows the network administrator to
sniff the observed ports 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 all ports whose network activity will be
monitored.
Mirror Port
Select the port number of all ports that will be used to monitor the
activity of the monitored ports.
Watch Direction
Select one of the following three watch direction options:
y Input data stream
Select this option to monitor only those data packets coming into
the PT-7728’s ports.
y Output data stream
Select this option to monitor only those data packets being sent out
through the PT-7728’s ports.
y Bi-directional
Select this option to monitor data packets both coming into, and
being sent out through, the PT-7728’s ports.
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.
Ping
The Ping function uses the ping command to give users a simple but powerful tool for
troubleshooting network problems. The function’s most unique feature is that even though the
ping command is entered from the user’s PC keyboard, the actual ping command originates from
PT-7728 itself. In this way, the user can essentially sit on top of PT-7728 and send ping commands
out through its ports.
To use the Ping function, type in the desired IP address, and then press Enter from the Console
utility, or click Ping when using the Web Browser interface.
