This section contains information for configuring port mirroring, running cable
tests, and viewing device operational information.

Testing Copper Ports
The Copper Test page displays the results of integrated cable tests performed on
copper cables by the Virtual Cable Tester (VCT).
VCT performs two types of tests:
• Time Domain Reflectometry (TDR) technology tests the quality and
characteristics of a copper cable attached to a port. Cables of up to 140
meters long can be tested. These results are displayed in the Test Results
block of the Copper Test page.
• DSP-based tests are performed on active GE links to measure cable length.
These results are displayed in the Advanced Information block of the
Copper Test page.
Preconditions to Running the Copper Port Test
Before running the test, do the following:
• (Mandatory) Disable Short Reach mode (see the Port Management > Green
Ethernet > Properties page)
