Command Usage
◆ OAM remote loop back can be used for fault localization and link performance
testing. Statistics from both the local and remote DTE can be queried and
compared at any time during loop back testing.
◆ Use the efm oam remote-loopback start command to start OAM remote loop
back test mode on the specified port. Afterwards, use the 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.
