Field Name

Field Description

Level of Output

Physical Interface

Physical Interface

Name of the physical interface type.

Enabled

State of the interface. Possible values are described in the “Enabled Field” section under Common Output Fields Description.

All levels

Interface index

Physical interface index number that 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

Type

Type of interface.

All levels

Link-level type

Encapsulation type used on the physical interface.

All levels

MTU

Maximum transmission unit—Size of the largest packet to be transmitted.

All levels

Clocking

Reference clock source of the interface.

All levels

Speed

Network speed on the interface.

All levels

Parent

Name and interface index of the interface to which a particular child interface belongs. None indicates that this is the top level.

detail extensive none

Device flags

Information about the physical device. Possible values are described in the “Device Flags” section under Common Output Fields Description.

All levels

Interface flags

Information about the interface. Possible values are described in the “Interface Flags” section under Common Output Fields Description.

All levels

Link type

Type of data transmission.

detail extensivenone

Link flags

Information about the link. Possible values are described in the “Link Flags” section under Common Output Fields Description.

detail extensive none

Physical info

Information about the physical interface.

detail extensive

Hold-times

Current interface hold-time up and hold-time down. Value is in milliseconds.

detail extensive

Current address

Configured MAC address.

detail extensive

Hardware address

MAC address of the hardware.

detail extensive

Alternate link address

Backup address for the link.

detail extensive

Last flapped

Date, time, and length of time since the interface changed its status from down to up.

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 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

  • Errors—Input errors on the interface.
  • Drops—Number of packets dropped by the output queue of the I/O Manager ASIC.
  • Framing errors—Number of packets received with an invalid frame checksum (FCS).
  • Runts—Frames received smaller than the runt threshold.
  • Giants—Frames received larger than the giant threshold.
  • Policed Discards—Frames that the incoming packet match code discarded because they were not recognized or were not of interest. Usually, this field reports protocols that Junos does not support.
  • Resource errors—Sum of transmit drops.

extensive

Output errors

  • 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, possibly once every 10 seconds, the cable, the remote system, or the interface is malfunctioning.
  • Errors—Sum of 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 dropped by the ASIC Red mechanism.
  • MTU errors—Number of packets larger than the MTU threshold.
  • Resource errors—Sum of transmit drops.

extensive

ISDN Alarms

ISDN alarms.

All levels

ISDN Media

  • LOF—Loss of frame
  • LOS—Loss of signal

extensive

Logical Interface

Logical interface

Name of the logical interface.

All levels

Index

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

detail extensive none

SNMP ifIndex

SNMP interface index number for 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 the “Logical Interface Flags” section under Common Output Fields Description.

All levels

Encapsulation

Encapsulation on the logical interface.

All levels

Input packets

Number of packets received on the logical interface.

None specified

Output packets

Number of packets transmitted on the logical interface.

None specified

Traffic statistics

Total number of bytes and packets received and transmitted on the logical interface. These statistics are the sum of the local and transit statistics. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize.

  • 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 logical interface.
  • Output packets—Number of packets transmitted on the logical interface

detail extensive

Local statistics

Statistics for traffic received from and transmitted to the Routing Engine. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize.
