Network Interfaces for EX4300 Switches
Table 49: show interfaces irb Output Fields (continued)
Field Name Field Description
Number and rate of bytes and packets received and transmitted on the physical
Traffic statistics
interface.
Input bytes
Output bytes
Input packets
Output packets
Number of IPv6 transit bytes and packets received and transmitted on the
IPv6 transit statistics
physical interface if IPv6 statistics tracking is enabled.
Input bytes
Output bytes
Input packets
Output packets
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
Giants
Policed discards
discarded because they were not recognized or not of interest. Usually, this
field reports protocols that the Junos OS does not handle.
Resource errors
Output errors on the interface. The following paragraphs explain the counters
Output errors
whose meaning might not be obvious:
Carrier transitions
up
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
Drops
ASIC. If the interface is saturated, this number increments once for every
packet that is dropped by the ASIC's RED mechanism.
MTU errors
interface.
Resource errors
