Statistics last cleared	Time when the statistics for the interface were last zeroed.
Traffic statistics	Statistics for traffic on the interface. Input bytes, Output bytes—Number of bytes received and transmitted on the interface. Input packets, Output packets—Number of packets received and transmitted on the interface.
Input errors	(Extensive output only) Input errors on the interface. The following paragraphs explain the nonobvious counters: Errors—Sum of the incoming 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. Invalid VCs—Number of cells that arrived for a nonexistent VC. Framing errors—Sum of AAL5 packets that have FCS errors, AAL5 packets that have reassembly timeout errors, and AAL5 packets that have length errors. Policed discards—Frames that the incoming packet match code discarded because they were not recognized or of interest. Usually, this field reports protocols that the JUNOS software does not handle, such as CDP. L3 incompletes—Increments when the incoming packet fails Layer 3 (usually IPv4) sanity checks of the header. For example, a frame with less than 20 bytes of available IP header would be discarded and this counter would increment. L2 channel errors—This 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 cause the incoming packet handler to discard the frame as unreadable.
Output errors	(Extensive output only) Output errors on the interface. The following paragraphs explain the nonobvious counters: Carrier transitions—Number of times the interface has gone from down to up. This number should not increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and up, or a similar problem occurs. If it increments quickly (perhaps once every 10 seconds), then either the cable, the far-end system, or the PIC is broken. 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.

These errors most likely indicate that a SONET/SDH layer problem has occurred. Correctable HCS errors—Number of correctable HCS errors that occurred. The cell delineation process can recover from these errors and locate the ATM cell boundary, although the framing process is not quite stable. The ATM cell is not dropped. This counter increases when the cell delineation process changes its state from present to sync (for example, when a fiber is plugged into the interface). The following error statistics are from the framer: Tx cell FIFO overruns—Number of overruns in the transmit FIFO. Rx cell FIFO overruns—Number of overruns in the receive FIFO.

When ATM has nothing to send, it sends idle cells to fill the time slot. Output VC queue drops—Number of packets dropped by a port on the PIC. Packets are dropped because of queue limits on the VCs. The following error statistics are from the SAR: Input no buffers—Number of AAL5 packets dropped because no channel blocks or buffers were available to handle them. Input length errors—Number of AAL5 packets dropped because their length was incorrect. Usually, these errors occur because a cell has been corrupted or lost, or because the length field was corrupted. They can also mean the AAL5 length field was zero. Input timeouts—Number of AAL5 packets dropped because of a reassembly timeout. Input invalid VCs—Number of AAL5 packets dropped because the header was unrecognized (because the VC was not correct or not configured). Input bad CRCs—Number of AAL5 packets dropped because of frame check sequence errors.
