Table 4: show interfaces Gigabit Ethernet Output Fields (continued)

Level of OutputField DescriptionField Name

extensiveCoS queue number and its associated user-configured forwarding class name.

Displayed on IQ2 interfaces.

• Queued packets—Number of queued packets.

• Transmitted packets—Number of transmitted packets.

• Dropped packets—Number of packets dropped by the ASIC's RED mechanism.

Queue counters

(Ingress)

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 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 alarms and

Active defects

detail extensive(On MX Series devices) Status of the interface-transmit-statistics configuration:

Enabled or Disabled.

• Enabled—When the interface-transmit-statistics statement is included in the

configuration. If this is configured, the interface statistics show the actual

transmitted load on the interface.

• Disabled—When the interface-transmit-statistics statement is not included

in the configuration. If this is not configured, the interface statistics show the

offered load on the interface.

Interface transmit

statistics

detail extensiveThe forward error correction (FEC) counters provide the following statistics:

• 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 extensive(10-Gigabit Ethernet interfaces) Displays Physical Coding Sublayer (PCS) fault

conditions from the WAN PHY or the LAN PHY device.

• Bit errors—High bit error rate. Indicates the number of bit errors when the PCS

receiver is operating in normal mode.

• Errored blocks—Loss of block lock. The number of errored blocks when the

PCS receiver is operating in normal mode.
