IMPORTANT:
• Fiber ports do not support this feature.
• If the link of an Ethernet port is up, testing its cable connection will cause the link to come down and then
go up.
The following matrix shows the feature and router compatibility:

You can test the cable connection of an Ethernet interface for a short or open circuit. The device displays
cable test results within 5 seconds. If any fault is detected, the test results include the length of the faulty
cable segment.
To test the cable connection of an Ethernet interface:
Step Command
1. Enter system view.
