Input packets, Output packets—Number of packets received and 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 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). Giants—Number of frames received that are larger than the giant threshold. Runts—Number of frames received that are smaller than the runt 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. L3 incompletes—Number of incoming packets discarded because they failed Layer 3 (usually IPv4) sanity checks of the header. For example, a frame with less than 20 bytes of available IP header is discarded. L2 channel errors—Counter increments when the software could not find a valid logical interface for an incoming frame. L2 mismatch timeouts—Count of malformed or short packets that caused the incoming packet handler to discard the frame as unreadable. HS link CRC errors—Count of errors on the high-speed links between the ASICs responsible for handling the router interfaces. SRAM errors—Number of hardware errors that occurred in the static RAM (SRAM) on the PIC. If the value in this field increments, the PIC is malfunctioning. 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, 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. Aged packets—Number of packets that remained in shared packet SDRAM so long that the system automatically purged them. The value in this field should never increment. If it does, it is most likely a software bug or possibly malfunctioning hardware. MTU errors—Number of packets whose size exceeds the MTU of the interface. Resource errors—Sum of transmit drops.	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
DS1 alarms DS1 defects	Media-specific defects that can render the interface unable to pass packets. When a defect persists for a certain amount of time, it is promoted to an alarm. Based on the router configuration, an alarm can ring the red or yellow alarm bell on the router, or turn on the red or yellow alarm LED on the craft interface. LOS—Loss of signal. LOF—Loss of frame. AIS—Alarm indication signal. YLW—Yellow alarm. Indicates errors at the remote site receiver.	detail extensive none
T1 media	Counts of T1 media-specific errors. Seconds—Number of seconds the defect has been active. Count—Number of times that the defect has gone from inactive to active. State—State of the error. State other than OK indicates a problem. The T1 media specific error types can be: AIS—Alarm indication signal BEE—Bit error event BES—Bit error seconds BPV—Bipolar violation CS—Carrier state ES—Errored seconds EXZ—Excessive zeros FEBE—Far-end block error LCV—Line code violation LES—Line error seconds LOF—Loss of frame LOS—Loss of signal PCV—Pulse code violation SEF—Severely errored framing SEFS—Severely errored framing seconds (section) SES—Severely errored seconds UAS—Unavailable seconds YELLOW—Errors at the remote site receiver	extensive
