192 FTBx-88000 Series
Modify Structure - Smart Loopback
PHY Type allows selecting the transceiver PHY type:
For 100GE (4 Lanes): LR4/ER4 (default), SR4, CWDM4, CLR4, AOC, or
Other. The PHY type when set to any except LR4/ER4, provides access
to RS-FEC configuration (see page 305).
For 100GE (1 Lane): DR1/FR1/LR1 (default and dimmed); ensure the
other end of the circuit has the FEC enabled.
For 100GE (2 Lanes): SRBD (default and dimmed); ensure the other
end of the circuit has the FEC enabled.
For 200GE (4 Lanes): Optical (default), and AOC.
For 400GE (8 Lanes): Optical (default), AOC, and DAC.
Connector allows the selection of the physical port (see the
Interface/Rate table above). Connectors availability depend on the
selected PHY Type; CFP8 and OSFP connectors are only available
when the PHY Type is set to Optical.
Loopback Mode
Transparent (Pseudo-Physical) check box when selected (cleared by
default) determines that the Smart Loopback operates as a physical
loopback by transmitting all received frames unaltered and without
discrimination. When the check box is cleared, the Loopback mode is
selectable from Loopback on page 421.
In transparent mode, the Network tab and the Ping & Trace Route
functions 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.
