Chapter SFE1000P Gigabit Ethernet Switch Administration Guide 18 Managing Device Diagnostics This section contains information for configuring port mirroring, running cable tests, and viewing device operational information, and includes the following topics: • Viewing Integrated Cable Tests • Performing Optical Tests • Configuring Port Mirroring • Defining CPU Utilization Viewing Integrated Cable Tests The Copper Ports Page contains fields for performing tests on copper cables. Cable testing provides information about where errors occurred in the cable, the last time a cable test was performed, and the type of cable error that occurred. The tests use Time Domain Reflectometry (TDR) technology to test the quality and characteristics of a copper cable attached to a port. Cables up to 100 meters long can be tested. Cables are tested when the ports are in the down state, with the exception of the Approximated Cable Length test. To test cables: 1. Click Admin > Diagnostics > Copper Ports. The Copper Ports Page opens: Copper Ports Page 2. Click the Test button to run the cable test. The results of the test appear. Chapter 18: Managing Device Diagnostics 140

Viewing Integrated Cable Tests
The
Copper Ports Page
contains fields for performing tests on copper cables. Cable testing provides
information about where errors occurred in the cable, the last time a cable test was performed, and
the type of cable error that occurred. The tests use Time Domain Reflectometry (TDR) technology to
test the quality and characteristics of a copper cable attached to a port. Cables up to 100 meters
long can be tested. Cables are tested when the ports are in the down state, with the exception of the
Approximated Cable Length test.
To test cables:
1.
Click
Admin
>
Diagnostics
>
Copper Ports
. The
Copper Ports Page
opens:
Copper Ports Page
2.
Click the
Test
button to run the cable test. The results of the test appear.
