Input errors

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).
Runts—Number of frames received that are smaller than the runt threshold.
Giants—Number of frames received that are larger than the giant threshold.
Bucket Drops—Drops caused by traffic load exceeding the interface transmit/receive leaky bucket configuration. The default is off.
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.
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—Number of times the software did not find a valid logical interface for an incoming frame.
L2 mismatch timeouts—Number of malformed or short packets that caused the incoming packet handler to discard the frame as unreadable.
HS link CRC errors—Number 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 of 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.
HS link FIFO underflows—Number of FIFO underflows on the high-speed links between the ASICs responsible for handling the router interfaces.
MTU errors—Number of packets whose size exceeds the MTU of the interface.
Resource errors—Sum of transmit drops.
