Table 49: show interfaces irb Output Fields (continued)
Level of OutputField DescriptionField Name
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.
Traffic statistics
detail extensiveNumber of IPv6 transit bytes and packets received and transmitted on the
physical interface if IPv6 statistics tracking is enabled.
• 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.
IPv6 transit statistics
detail 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.
• 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 OS does not handle.
• Resource errors—Sum of transmit drops.
Input errors
detail extensiveOutput 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 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 DPC 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 transmit drops.
