Transparent (Pseudo-Physical ) check box when selected (cleared by
default), determines that the Loopback tool operates as a physical
loopback by transmitting all received frames unaltered and without
discrimination.
In transparent mode, the Network tab and the S-OAM Responder
statistics are not available.
Note: The Transparent mode is intended to be used for point-to-point topology;
not for switched or routed networks. Use the Transparent mode with
caution because all received frames are looped back without
discrimination.
