Output Fields

Table 24 lists the output fields for the show interfaces (Aggregated Ethernet) command. Output fields are listed in the approximate order in which they appear.
Table 24: Aggregated Ethernet show interfaces Output Fields

Field Name

Field Description

Level of Output

Physical Interface

Physical interface

Name of the physical interface and state of the interface.

All levels

Enabled

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

All levels

Interface index

Index number of the physical interface, which reflects its initialization sequence.

All levels

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

Maximum transmission unit size on the physical interface.

All levels

Speed

Speed at which the interface is running.

All levels

Loopback

Loopback status: Enabled or Disabled. If loopback is enabled, type of loopback: Local or Remote.

All levels

Source filtering

Source filtering status: Enabled or Disabled.

All levels

Flow control

Flow control status: Enabled or Disabled.

All levels

Minimum links needed

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

All levels

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

Current address

Configured MAC address.

detail extensive

Hardware address

Hardware MAC address.

detail extensive

Last flapped

Date, time, and how long ago the interface went from down to up. The format is Last flapped: year-month-day hours:minutes:seconds timezone (hours:minutes:seconds ago). For example, Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago).

detail extensive

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 and rate of bytes and packets received and transmitted on the physical interface.

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:

Errors—Sum of 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.

detail extensive

Output errors

(Extensive only) 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 then 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 exceeded the MTU of the interface.

Resource errors—Sum of transmit drops.

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.

detail extensive

Logical Interface

Logical interface

Name of the logical interface.

Index number of the logical interface (which reflects its initialization sequence).

detail extensive none

SNMP ifIndex

SNMP interface index number of the logical interface.

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.

Encapsulation

Encapsulation on the logical interface.

All levels

Marker Statistics—(detail and extensive only) Information about 802.3ad marker protocol statistics on the specified links.

Marker Rx—Number of valid marker PDUs received on this aggregation port.

Resp Tx—Number of marker response PDUs transmitted on this aggregation port.

Unknown Rx—Number of frames received that either carry the slow protocols Ethernet type value (43B.4), but contain an unknown PDU, or are addressed to the slow protocols group MAC address (43B.3), but do not carry the slow protocols Ethernet type.

Illegal Rx—Number of frames received that carry the slow protocols Ethernet type value (43B.4), but contain a badly formed PDU or an illegal value of protocol subtype (43B.4).
