1.3 Display and Debug Ethernet Port

After the above configuration, execute display command in any view to display the
running of the Ethernet port configuration, and to verify the effect of the configuration.
Execute loopback command in Ethernet port view to check whether the Ethernet port
works normally. In the process of the loopback test, the port cannot forward the packets.
The loop test will finish automatically after being executed for a while.
Using virtual-cable-test command in Ethernet port view, you can get the information of
the cable test in 5 seconds. The test information includes the condition of the cable
( open or short ) , and the distance between the ethernet port and the cable with fault.
S3552G/S3552P/S3552F/S3528G/S3528P support the command.
Execute reset command in user view to clear the statistics information of the port.

Note that the loopback test cannot be performed on the port disabled by the shutdown
command. During the loopback test, the system will disable speed, duplex, mdi and
shutdown operation on the port. Some ports do not support the loopback test. If
performing this command in these ports, you will see the system prompt.
S3526/S3526 FS/S3526 FM/S3526E/S3526C Ethernet Switches support display
loopback-detection command in S3500 series switches.
