Command Usage
• You can use this command to perform an OAM remote loopback test on the specified port. 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.
• OAM remote loopback 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
loopback testing.
• A summary of the test is displayed after it is finished.
