Traffic statistics

Number 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.

detail extensive

Input errors

Input errors on the interface:

Errors—Sum of 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.

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 software does not handle.

Resource errors—Sum of B chip Tx drops and IXP Tx net 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 PIM 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.

MTU errors—Number of packets whose size exceeded the MTU of the interface.

Resource errors—Sum of B chip Tx drops and IXP Tx net transmit drops.
