Description
Use the virtual-cable-test command to enable the system to test the cable connected
to the specific port and to display the results. The system can test these attributes of the
cable:
z Cable status, including normal, abnormal, abnormal-open, abnormal-short and
failure
z Cable length
Note:
z If the cable is in normal state, the displayed information is “-”.
z If the cable is in any other state, the displayed length value is the length from the
port to the faulty point.
z Pair impedance mismatch
z Pair skew
z Pair swap
z Pair polarity
z Insertion loss
z Return loss
z Near-end crosstalk
By default, the system does not test the cable connected to the Ethernet port.
Note:
z The combo port does not support the virtual-cable-test command.
z The acceptable deviation of the cable length tested through the virtual-cable-test
command is ±5m.
Examples
# Enable the system to test the cable connected to Ethernet 2/0/1.
