Virtual Cable Test
Use the Virtual Cable Test facility to diagnose the type of cable fault and the
approximate distance to a cable fault. The Virtual Cable Test facility tests all
four pairs of wires inside the cable and is supported on Gigabit Ethernet RJ-45
ports.
The AT9924T and AT9924T/4SP switches support this feature.
How to use the Virtual Cable Test
To locate cable faults for a specific port or all ports on the switch, use the
command:
enable test cable [port={port-number|all}]
If the test is not finished in 10 seconds then the test is halted and an error
message is displayed.
Warning After the enable test cable command is entered do not connect or
disconnect the cable of the port under test. The RJ-45 ports 1 to 4 use the same
physical interface as the SFP ports 1 to 4. If the RJ-45 port under test is ports 1 to
4, do not insert a SFP into a SFP port that corresponds to this port. When a SFP
is inserted the corresponding RJ-45 port is disabled.
