VCT
Overview
NOTE:
The fiber interface of a SFP port does not support this feature.
A link in the up state goes down and then up automatically if you perform this operation on one of the
Ethernet interfaces forming the link.
You can use the Virtual Cable Test (VCT) function to check the status of the cable connected to an Ethernet
port on the device. The check result is returned in less than 5 seconds. The test covers whether short circuit
or open circuit occurs on the cable and the length of the faulty cable.
Testing cable status
Select Device > VCT from the navigation tree to enter the page for testing cable status. Select the port you
want to test in the chassis front panel and then click Test. The test result is returned in less than 5 seconds
and displayed in the Result text box, as shown in Figure 71.
