is Last flapped: year-month-day hour:minute:second timezone (hour:minute:second

ago). For example, Last flapped: 2008–01–16 10:52:40 UTC (3d 22:58 ago).

detail extensiveNumber and rate of bytes and packets received and transmitted on the physical

interface.

• Input bytes—Number of bytes received on the interface.

• Output bytes—Number of bytes transmitted on the interface.

• Input packets—Number of packets received on the interface

• Output packets—Number of packets transmitted on the interface.

NOTE: The bandwidth bps counter is not enabled on the switch.

Traffic statistics

extensiveInput 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).

• 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 OS does not handle.

• L3 incompletes—Number of incoming packets discarded because they failed

Layer 3 sanity checks of 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 that 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 nonzero, the PIC is probably

malfunctioning.

• Resource errors—Sum of transmit drops.
