Field Name Field Description
Input errors on the interface. The following paragraphs explain the counters
Input errors
whose meaning might not be obvious:
Errors
Drops
ASIC. If the interface is saturated, this number increments once for every
packet that is dropped by the ASIC's RED mechanism.
Framing errors
(FCS).
Runts
Policed discards
discarded because they were not recognized or not of interest. Usually, this
field reports protocols that the Junos OS does not handle.
L3 incompletes
Layer 3 (usually IPv4) sanity checks of the header. For example, a frame with
less than 20 bytes of available IP header is discarded. L3 incomplete errors
can be ignored by configuring the
L2 channel errors
interface for an incoming frame.
L2 mismatch timeouts
the incoming packet handler to discard the frame as unreadable.
FIFO errors
by the ASIC on the PIC. If this value is ever nonzero, the PIC is probably
malfunctioning.

—Sum of the incoming frame aborts and FCS errors.
—Number of packets dropped by the input queue of the I/O Manager
—Number of packets received with an invalid frame checksum

—Number of frames that the incoming packet match code
—Number of incoming packets discarded because they failed
