Network Interfaces for EX4300 Switches

Field Name Field Description
Current interface hold-time up and hold-time down, in milliseconds.
Hold-times
Configured MAC address.
Current address
MAC address of the hardware.
Hardware address
Date, time, and how long ago the interface went from down to up. The format
Last flapped
is
Last flapped: year-month-day hour:minute:second timezone (hour:minute:second
. For example,
ago)
Time when the statistics for the interface were last set to zero.

Number and rate of bytes and packets received and transmitted on the physical

NOTE:
Input errors Input errors on the interface. The following paragraphs explain the counters
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 sanity checks of the headers. For example, a frame with less than 20
bytes of available IP header is discarded.
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.
Resource errors

Last flapped: 2008–01–16 10:52:40 UTC (3d 22:58 ago).
—Number of bytes received on the interface.
—Number of bytes transmitted on the interface.
—Number of packets received on the interface
—Number of packets transmitted on the interface.
The bandwidth bps counter is not enabled on the switch.
—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 received that are smaller than the runt threshold.
—Number of frames that the incoming packet match code
—Number of incoming packets discarded because they failed
—Number of times the software did not find a valid logical
—Number of malformed or short packets that caused
—Number of FIFO errors in the receive direction that are reported
—Sum of transmit drops.
