Ethernet interface loopback testing should be enabled while testing certain
■
functionalities, such as during the initial identification of any network failure.
While enabled, Ethernet interface loopback testing will work in a full-duplex
■
mode. The interface will return to its original state upon completion of the
loopback testing.

According to the layer at which the device processes received data packets,
Ethernet interfaces can work in bridge or route mode. For a device, some
interfaces can work only in bridge mode, some can work only in route mode, and
others can work in bridge mode or route mode. This command is only applicable
to Ethernet interfaces whose working mode can be changed.
