Command Usage
â—† 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.
â—† During a remote loopback test, the remote OAM entity loops back every frame
except for OAMPDUs and pause frames.
â—† 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.
â—† A summary of the test is displayed after it is finished.
