Usage Guidelines
This command puts the remote peer device into loopback mode. This means that all traffic sent to the peer is
looped back, which means that it is sent back from the peer and received by the router. All traffic received
from the peer device is discarded.
This command returns when the OAM client receives confirmation from the remote end that the remote
loopback has been enabled or disabled. If no response or a failure response is received, an error is returned.
