Output Fields

Table 50 lists the output fields for the show interfaces (aggregated SONET/SDH) command. Output fields are listed in the approximate order in which they appear.
Table 50: Aggregated SONET/SDH show interfaces Output Fields

Field Name

Field Description

Level of Output

Physical Interface

Physical interface

Name of the physical interface.

All levels

Enabled

State of the interface. Possible values are described in Enabled Field.

All levels

Interface index

Physical interface's index number, which reflects its initialization sequence.

detail extensive none

SNMP ifIndex

SNMP index number for the physical interface.

detail extensive none

Generation

Unique number for use by Juniper Networks technical support only.

detail extensive

Link-level type

Encapsulation being used on the physical interface.

All levels

MTU

MTU size on the physical interface.

All levels

Speed

Speed at which the interface is running.

All levels

Minimum links needed

Number of child links that must be operational for the aggregated interface to be operational.

detail extensive none

Device flags

Information about the physical device. Possible values are described in Device Flags.

All levels

Interface flags

Information about the interface. Possible values are described in Interface Flags.

All levels

Link flags

Information about the link. Possible values are described in Link Flags.

All levels

Keepalive settings

(PPP and HDLC) Configured settings for keepalives.

interval seconds—The time in seconds between successive keepalive requests. The range is 10 seconds through 32,767 seconds, with a default of 10 seconds.

up-count number—The number of keepalive packets a destination must receive to change a link's status from down to up. The range is 1 through 255, with a default of 1.

down-count number—The number of keepalive packets a destination must fail to receive before the network takes a link down. The range is 1 through 255, with a default of 3.

All levels

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). For example, Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago).

detail extensive none

Input rate

Input rate in bits per second (bps) and packets per second (pps).

None specified

Output rate

Output rate in bps and pps.

None specified

Statistics last cleared

Time when the statistics for the interface were last set to zero.

detail extensive

Traffic statistics

Number of bytes and packets received and transmitted on the physical interface, and the traffic rate in bits per seconds (bps).

Input bytes—Number of bytes received on the interface.

Output bytes—Number of bytes transmitted on the interface.

Input packets—Number of packets received on the interface.

Output packets—Number of packets transmitted on the interface.

detail extensive

Input errors

Input errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:

Errors—Sum of the incoming frame aborts and FCS errors.

Drops—Number of packets dropped by the input queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.

Framing errors—Number of packets received with an invalid frame checksum (FCS).

Runts—Number of frames received that are smaller than the runt threshold.

Giants—Number of frames received that are larger than the giant threshold.

Policed discards—Number of frames that the incoming packet match code discarded because they were not recognized or not of interest. Usually, this field reports protocols that the JUNOS software does not handle.

Resource errors—Sum of transmit drops.

extensive

Output errors

Output errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:

Carrier transitions—Number of times the interface has gone from down to up. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), the cable, the far-end system, or the PIC is malfunctioning.

Errors—Sum of the outgoing frame aborts and FCS errors.

Drops—Number of packets dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.

MTU errors—Number of packets whose size exceeds the MTU of the interface.

Resource errors—Sum of transmit drops.

extensive

Egress queues

Total number of egress queues supported on the specified interface.

detail extensive

Queue counters

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

Queued packets—Number of queued packets.

Transmitted packets—Number of transmitted packets.

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

extensive

Logical Interface

Logical interface

Name of the logical interface.

All levels

Index

Logical interface's index number (which reflects its initialization sequence).

detail extensive none

SNMP ifIndex

Logical interface's SNMP interface index number.

detail extensive none

Generation

Unique number for use by Juniper Networks technical support only.

detail extensive

Flags

Information about the logical interface. Possible values are described in Logical Interface Flags.

All levels

Encapsulation

Encapsulation on the logical interface.

All levels

Bandwidth

Interface bandwidth.

detail extensive none

Statistics

Information about fragments and packets received and sent by the router All references to traffic direction (input or output) are defined with respect to the router. Input fragments received by the router are assembled into input packets; output packets are segmented into output fragments for transmission out of the router.

Statistics include input and output counts for packets, packets per second (pps), bytes, and bytes per second (Bps) for the following entities:

Bundle—Information about bundles.

Link—Information about links used in the multilink operation.

detail extensive none

protocol-family

Protocol family configured on the logical interface. If the protocol is inet, the source and destination address are also displayed.
