Output Fields

Table 1 lists the output fields for the show interfaces (Aggregated Ethernet) command. Output fields are listed in the approximate order in which they appear.

Table 1: 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 .	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 .	All levels
Interface flags	Information about the interface. Possible values are described in .	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 or up to down. 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	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
IPv6 transit statistics	Number of IPv6 transit bytes and packets received and transmitted on the physical interface if IPv6 statistics tracking is enabled. 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
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.	All levels
Index	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 .	All levels
VLAN-Tag	The TPID and VLAD identifier.	All levels
Demux	IP demultiplexing (demux) value that appears if this interface is used as the demux underlying interface. The output is one of the following: Source Family Inet Destination Family Inet	detail extensive none
Encapsulation	Encapsulation on the logical interface.	All levels
Statistics	Information about the number of packets, packets per second, number of bytes, and bytes per second on this aggregate interface. Bundle—Information about input and output bundle rates. Link—(detail and extensive only) Information about specific links in the aggregate, including link state and input and output rates. 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 protocol data unit (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).	detail extensive none
protocol-family	Protocol family configured on the logical interface. Possible values are described in .	brief
Protocol	Protocol family configured on the logical interface. Possible values are described in .	detail extensive none
MTU	Maximum transmission unit size on the logical interface.	detail extensive none
Generation	Unique number for use by Juniper Networks technical support only.	detail extensive
Route Table	Routing table in which the logical interface address is located. For example, 0 refers to the routing table inet.0.	detail extensive
Flags	Information about protocol family flags. Possible values are described in .	detail extensive none
Mac-Validate Failures	Number of MAC address validation failures for packets and bytes. This field is displayed when MAC address validation is enabled for the logical interface.	detail extensive none
