40 CONFIGURING THE SWITCH
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.
CAUTION: The analyzer port should have a higher
bandwidth than the monitor port. Otherwise, the
Switch may not be able to copy all traffic effectively
during periods of high traffic.
Figure 21 Traffic Monitoring Screen
To set up traffic monitoring for a port:
1 Attach a network analyzer to a port.
2 Access the Web interface, and then click Port Mirroring
on the menu.
3 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.
4 Click Apply.
For information on how to interpret the output on the
port analyzer, refer to its accompanying documentation.
Running Cable Diagnostic
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
■ Link Information
To run the tests on a port:
1 In Port, select a port number to diagnose.
2 Click Apply.
