Field Description
Ethernet-specific defects that can prevent the interface from passing packets.
When a defect persists for a certain amount of time, it is promoted to an alarm.
Based on the router configuration, an alarm can ring the red or yellow alarm
bell on the router, or turn on the red or yellow alarm LED on the craft interface.
These fields can contain the value None or Link.
• None—There are no active defects or alarms.
• Link—Interface has lost its link state, which usually means that the cable is
unplugged, the far-end system has been turned off, or the PIC is
malfunctioning.
Active OTN alarms identified on the interface.
OTN defects received on the interface.
The FECmode configured on the interface.
• efec—Enhanced forward error correction (EFEC) is configured to defect and
correct bit errors.
• gfec—G.709 Forward error correction (GFEC) mode is configured to detect
and correct bit errors.
• none—FEC mode is not configured.
OTN mode.
• fixed-stuff-bytes—Fixed stuff bytes 11.0957 Gbps.
• no-fixed-stuff-bytes—No fixed stuff bytes 11.0491 Gbps.
• pass-through—Enable OTN passthrough mode.
• no-pass-through—Do not enable OTN passthrough mode.
Status of the line loopback, if configured for the DWDM OTN PIC. Its value can
be: enabled or disabled.
The forward error correction (FEC) counters for the DWDM OTN PIC.
• Corrected Errors—The count of corrected errors in the last second.
• Corrected Error Ratio—The corrected error ratio in the last 25 seconds. For
example, 1e-7 is 1 error per 10 million bits.
OTN FEC excessive or degraded error alarms triggered on the interface.
• FEC Degrade—OTU FEC Degrade defect.
• FEC Excessive—OTU FEC Excessive Error defect.
OTN OC defects triggered on the interface.
• LOS—OC Loss of Signal defect.
• LOF—OC Loss of Frame defect.
• LOM—OC Loss of Multiframe defect.
• Wavelength Lock—OC Wavelength Lock defect.
