Table 6: show interfaces Gigabit Ethernet Output Fields (continued)

Level of OutputField DescriptionField Name

detail extensive noneEthernet-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 routing device configuration, an alarm can ring the red or yellow

alarm bell on the routing device, 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 defects

detail extensiveActive OTN alarms identified on the interface.OTN alarms

detail extensiveThe 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 FEC Mode

detail extensiveOTN 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.

OTN Rate

detail extensiveStatus of the line loopback, if configured for the DWDM OTN PIC. Its value can

be: enabled or disabled.

OTN Line Loopback

detail extensiveThe 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 statistics

detail extensiveOTN FEC excessive or degraded error alarms triggered on the interface.

• FEC Degrade—OTU FEC Degrade defect.

• FEC Excessive—OTU FEC Excessive Error defect.

OTN FEC alarms

detail extensiveOTN 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.
