If encapsulation does not match, then configure the incorrect side to match up.
CLI config interface 11star1
<shelf slot>
shelf slot/C1 tengige encmode [ cbrlan11.049 |

Ensure that there are no channel alarms or conditions for this channel on the near-end NE.
If there are, clear them.

4
Query for the optical receive power on the network port where the LOF condition is
present.
CLI sh int
<shelf slot port>
...................................................................................................................................................................................................
5
If... Then...
the optical power is below the required
threshold,
using standard optical fiber jumper cleaning
procedure, clean the fiber, and measure the
power again.
the optical power is within the required limits, clean the receive connector on the card.

Confirm that the drop path is fibered correctly:
1. Confirm that the network port of the transponder is fibered to the appropriate port on
the appropriate OT.
2. Confirm that the mux port of the OT is fibered to the appropriate port on the
appropriate CWR8.
3. Verify that there is a fiber properly plugged into the alarmed port.
4. Verify that the fiber is the correct type (multi-mode / single mode) and that the other
end of the fiber is connected properly.

7
Perform a line loop-back on the far end network port. If this resolves the local (near-end)
alarm then the problem is associated with the far end card.
