Loopback test configuration
Overview
You can check whether an Ethernet port works normally by performing the Ethernet port loopback test,
during which the port cannot forward data packets normally.
Ethernet port loopback test can be an internal loopback test or an external loopback test.
 In an internal loopback test, self loop is established in the switching chip to check whether there is
a chip failure related to the functions of the port.
 In an external loopback test, a loopback plug is used on the port. Packets forwarded by the port will
be received by itself through the loopback plug. The external loopback test can be used to check
whether there is a hardware failure on the port.
Loopback operation
Select Device > Loopback from the navigation tree to enter the loopback test configuration page, as
