efm oam remote-loopback test command to start sending test packets.
Then use the efm oam remote loopback stop command to terminate
testing (if test packets are still being sent) and to terminate loop back
test mode.
◆ The port that you specify to run this test must be connected to a peer
OAM device capable of entering into OAM remote loopback mode.
During a remote loopback test, the remote OAM entity loops back every
frame except for OAMPDUs and pause frames.
◆ During loopback testing, both the switch and remote device are
permitted to send OAMPDUs to the peer device and to process any
OAMPDUs received from the peer.
