NPort S8000 Series Switch Featured Functions

6-59

Mirror Port Settings

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.

Perform the following steps to set up the Mirror Port function:

1. Configure the S8000 series’ 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

three watch direction options:

•

Input data stream

Select this option to monitor only those data packets coming in through the

S8000 series’ port.

•

Output data stream

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

the

S8000 series’ port.

•

Bi-directional

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

out

through, the S8000 series’ port.

2. Be sure to activate your settings before exiting.

 When using the Web Browser interface, activate by clicking Activate.

 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.

TFTP Settings

System File Update—By Remote TFTP

The NPort S8000 supports saving your configuration file to a remote TFTP server or local host to allow other

NPort S8000 switches to use the same configuration at a later time, or saving the Log file for future reference.

Loading pre-saved firmware or a configuration file from the TFTP server or local host is also supported for easy

upgrading or configuration of the NPort S8000.
