Current address	Configured MAC address.	detail extensive
Hardware address	MAC address of the hardware.	detail extensive
Alternate link address	Backup address of the link.	detail extensive
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
IPv6 transit statistics	Number of IPv6 transit bytes and packets received and transmitted on the physical interface if IPv6 statistics tracking is enabled. Note: These fields include dropped traffic and exception traffic, as those fields are not separately defined. 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 OS does not handle. Resource errors—Sum of B chip Tx drops and IXP Tx net 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 then up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), then the cable, the far-end system, or the 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 B chip Tx drops and IXP Tx net transmit drops.	extensive
Logical Interface
Logical interface	Name of the logical interface.	All levels
Index	Logical interface index number (which reflects its initialization sequence).	detail extensive none
SNMP ifIndex	Logical interface 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 the “Logical Interface Flags” section under Common Output Fields Description.	All levels
Encapsulation	Type of encapsulation configured on the logical interface.	All levels
PPP parameters	PPP status: LCP restart timer—Length of time (in milliseconds) between successive Link Control Protocol (LCP) configuration requests. NCP restart timer—Length of time (in milliseconds) between successive Network Control Protocol (NCP) configuration requests.	detail
PPPoE	PPPoE status: State—State of the logical interface (up or down). Session ID—PPPoE session ID. Service name—Type of service required. Can be used to indicate an Internet service provider (ISP) name or a class or quality of service. Configured AC name—Configured access concentrator name. Auto-reconnect timeout—Time after which to try to reconnect after a PPPoE session is terminated, in seconds. Idle Timeout—Length of time (in seconds) that a connection can be idle before disconnecting. Underlying interface—Interface on which PPPoE is running.	All levels
Link	Name of the physical interfaces for member links in an aggregated Ethernet bundle for a PPPoE over aggregated Ethernet configuration. PPPoE traffic goes out on these interfaces.	All levels
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. This counter usually takes less than 1 second to stabilize.	detail extensive
IPv6 transit statistics	Number of IPv6 transit bytes and packets received and transmitted on the logical interface if IPv6 statistics tracking is enabled. Note: The packet and byte counts in these fields include traffic that is dropped and does not leave the router. 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
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. This counter usually takes less than 1 second to stabilize.	detail extensive
Transit statistics	Statistics for traffic transiting the router. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. This counter usually takes less than 1 second to stabilize. Note: The packet and byte counts in these fields include traffic that is dropped and does not leave the router.	detail extensive
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. down-countnumber—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. 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.	detail extensive
Keepalive statistics	(PPP and HDLC) Information about keepalive packets. Input—Number of keepalive packets received by PPP. (last seen 00:00:00 ago)—Time the last keepalive packet was received, in the format hh:mm:ss. Output—Number of keepalive packets sent by PPP and how long ago the last keepalive packets were sent and received. (last seen 00:00:00 ago)—Time the last keepalive packet was sent, in the format hh:mm:ss. (MX Series routers with MPCs/MICs) When an MX Series router with MPCs/MICs is using PPP fast keepalive for a PPP link, the display does not include the number of keepalive packets received or sent, or the amount of time since the router received or sent the last keepalive packet.	detail extensive
