Diagnose Cabling Problems
Use the Diagnostics window to run the Broken Wire Detection test, which uses
Time Domain Reflectometry (TDR) detection to identify, diagnose, and resolve
cabling problems. TDR detection is supported on copper Ethernet 10/100 and
10/100/1000 ports. TDR is not supported on small form-factor pluggable (SFP)
module ports.
The link test can interrupt traffic between the port and the connected device.
Only run the test on a port that has a suspected problem. Before running the link
test, use the Front Panel view, the Port Status, and the Port Statistics windows to
gather information about a potential problem.
To diagnose cabling, from the Monitor menu, choose Diagnostics.
To run a test, select a port and then click Start.
IMPORTANT
To run a valid test on gigabit ports, you must first configure the gigabit port as
an RJ45 media type, as described in
