THE

 S

WITCH

you need to attach a network analyzer to one port and 
use it to monitor the traffic of other ports in the stack.

To set up traffic monitoring, you need to set an analyzer 
port (the port that is connected to the analyzer), and a 
monitor port (the port that is to be monitored). Once 
the pair is defined, and you enable traffic monitoring, 
the Switch takes all the traffic going in and out of the 
monitor port and copies it to the analyzer port.

Figure 21   Traffic Monitoring Screen

To set up traffic monitoring for a port:

Attach a network analyzer to a port.

Access the Web interface, and then click Port Mirroring 
on the menu.

Specify the monitor port and analyzer port from the list.

■

Monitor Port — This is the port that is to be 
monitored.

■

Analyzer Port — This is the port to which the 
analyzer is attached.

Click Apply.

For information on how to interpret the output on the 
port analyzer, refer to its accompanying documentation.

The Switch provides cable diagnostic, which helps you 
detect and resolve issues with the attached cables. The 
Switch will run three types of cable diagnostic tests:

■

Basic Diag (Pair Quality and Pair Skew)

■

Pair Wiring
