Output Fields

Table 1 lists the output fields for the show interfaces diagnostics optics-applications command.

Table 1: show interfaces diagnostics optics-applications Output Fields
Field Name	Field Description
Physical interface	Name of the physical interface.
Interface index	Index number of the physical interface, which reflects its initialization sequence.
Wavelength	Wavelength of the optics in nm.
Media Code	Describes the line side configuration.
Host Code	Describes the system side configuration.
Device Flags	Provides information about the physical interface.
Interface Flags	Provides information about the physical interface.
CoS queues	Number of CoS queues configured.
Current address	Configured MAC address.
Last Flapped	Date, time, and how long ago the interface went from down to up. The format is Last flapped: year-month-day hour :minute :second :timezone (hour :minute :second ago).
Input rate	Input rate in bits per second (bps) and packets per second (pps). Thevalue in this field also includes the Layer 2 overhead bytes for ingress traffic on Ethernet interfaces if you enable accounting of Layer 2 overhead at the PIC level or the logical interface level.
Output Rate	Output rate in bps and pps. The value in this field also includes the Layer 2 overhead bytes for egress traffic on Ethernet interfaces if you enable accounting of Layer 2 overhead at the PIC level or the logical interface level.
Active alarms and Active defects	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 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.
PCS statistics	Displays Physical Coding Sublayer (PCS) fault conditions from the WAN PHY or the LAN PHY device.
Last Flapped	Date, time, and how long ago the interface went from down to up. The format is Last flapped: year-month-day hour :minute :second :timezone (hour :minute :second ago).
