Output Fields

Table 1 lists the output fields for the show interfaces me0 command. Output fields are listed in the approximate order in which they appear.

Table 1: show interfaces me0 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: Enabled or Disabled.	All levels
Interface index	Index number of the physical interface, 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
Description	Optional user-specified description.	brief detail extensive
Type	Information about the type of functional interface.	All levels
Link-level type	Encapsulation being used on the physical interface.	All levels
MTU	Maximum transmission unit size on the physical interface. The default is 1514.	All levels
Clocking	Interface that acts as a clock source. This field is not supported on EX Series switches and the default value is always Unspecified.	detail extensive
Speed	Speed at which the interface is running.	All levels
Device flags	Information about the physical device.	All levels
Interface flags	Information about the interface.	All levels
Link type	Information about whether the link is duplex and whether the negotiation is manual or automatic.	detail extensive none
Physical info	Information about the device dependent physical interface selector. This field is applied only when a clocking option is specified. This field is not supported on EX Series switches and the default value is always Unspecified.	detail extensive
Hold-times	Current interface hold-time up and hold-time down, in milliseconds.	detail extensive
Current address	Configured MAC address.	detail extensive none
Hardware address	MAC address of the hardware.	detail extensive none
Alternate link address	Information about alternate hardware 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 hour:minute:second timezone (weeksw:daysdhour:minute:second ago). For example, Last flapped: 2008–01–16 10:52:40 UTC (3w:3d 22:58 ago).	detail extensive none
Statistics last cleared	Time when the statistics for the interface was last set to zero. The format is Last flapped: year-month-day hour:minute:second timezone (weeksw:daysdhour:minute:second ago). For example, Last flapped: 2008–01–16 10:52:40 UTC (3w:3d 22:58 ago).	detail extensive
Traffic statistics	Number and rate of bytes and packets received and transmitted on the physical interface. Following are fields in Traffic statistics: 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
IPv6 transit statistics	Number and rate of bytes and IPv6 packets received and transmitted on the physical interface. Following are fields in IPv6 transit statistics: 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 frame checksum (FCS) errors. Drops—Number of packets dropped by the input queue of the I/O Manager ASIC. Framing errors—Number of packets received with an invalid FCS. Runts—Number of frames received that are smaller than the runt threshold. Giants— Number of packets that exceed the size for the medium. For example, if the medium is Ethernet, the Giant field shows the count of packets with size greater than 1518 bytes. 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 OS 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. It increases 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 increment quickly (perhaps once every 10 seconds), the cable, the far-end system, or the PIC or PIM 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.	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.	All levels
Encapsulation	Encapsulation on the logical interface.	All levels
Traffic statistics	Number and rate of bytes and packets received (input) and transmitted (output) on the specified interface.	detail extensive
IPv6 transit statistics	If IPv6 statistics tracking is enabled, number of IPv6 bytes and packets received and transmitted on the logical interface.	detail extensive
Local statistics	Number and rate of bytes and packets destined to and exiting from the switch.	extensive
Protocol	Protocol family.	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.	detail extensive
Input Filter	Ingress filter name.	extensive
Output Filter	Egress filter name.	extensive
Addresses	Information about the management interface addresses.	detail extensive none
Flags	Information about the address flags.	detail extensive none
Destination	IP address of the remote side of the connection.	detail extensive none
Local	IP address of the logical interface.	detail extensive none
Broadcast	Broadcast address of the logical interface.	detail extensive none
Generation	Unique number for use by Juniper Networks technical support only.	detail extensive
