Configuration guidelines
Note the following when performing a loopback test:
 You can perform an internal loopback test but not an external loopback test on a port that is physically
down, but you can perform neither test on a port that is manually shut down.
 The system does not allow Rate, Duplex, Cable Type and Port Status configuration on a port under a
loopback test.
 An Ethernet port works in full duplex mode when the loopback test is performed, and restores its
original duplex mode after the loopback test.
