4.2.2 Link Loss Forwarding
When Link Loss Forwarding (LLF) is enabled, a fault on one side of the 9161 propagates to the
other side to notify that device and stops signal transmission (see Figure 5-2). Set the LLF prop-
agation to 10G1 to 10G2, 10G2 to 10G1, or both directions. Set this in the User Interface at the
Functional Configuration screen (reference Chapter 3).
