CAUSE:

SOLUTION:

The errors can be classified as Input and Output. Input errors account for the erroneous counters, which occur at the input queue of SRX interface.

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 received frames that are smaller than the runt threshold.

Policed discards: Number of frames that the incoming packet match code discarded, as 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, as they have failed Layer 3 sanity checks for the headers. 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 which caused the incoming packet handler to discard the frame as unreadable.

FIFO errors: Number of FIFO errors in the receive direction that are reported by the ASIC on the PIC. If this value is ever non-zero, the PIC is probably malfunctioning.

Resource errors: Sum of transmit drops.

Output errors can be broadly summarized as follows:

Carrier transitions: Number of times that 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 issue occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), the cable, far-end system, PIC or PIM is malfunctioning.
Errors: Sum of the outgoing frame aborts and FCS errors.
Drops: The number of packets which are dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet, which is dropped by the ASIC's RED mechanism.
Collisions: The number of Ethernet collisions. The Gigabit Ethernet PIC supports only full-duplex operation; so for Gigabit Ethernet PICs, this number should always remain 0. If it is non-zero, there is a software bug.
Aged packets: The number of packets which remained in the shared packet SDRAM for 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 possible malfunctioning hardware.
FIFO errors: The number of FIFO errors in the send direction, as reported by the ASIC on the PIC. If this value is ever non-zero, the PIC is probably malfunctioning.
HS link CRC errors: The number of errors on the high-speed links between the ASICs, which are responsible for handling the router interfaces.
MTU errors: The number of packets whose size exceeded the interface MTU.
Resource errors: Sum of transmit drops.
