Description
Field
Total number of no buffer, runts, giants, cyclic
redundancy checks (CRCs), frame, overrun, ignored,
and abort counts. Other input-related errors can also
increment the count, so that this sum might not
balance with the other counts.
input errors
CRC generated by the originating LAN station or
far-end device does not match the checksum
calculated from the data received. On a LAN, this
usually indicates noise or transmission problems on
the LAN interface or the LAN bus. A high number
of CRCs is usually the result of collisions or a station
transmitting bad data. On a serial link, CRCs usually
indicate noise, gain hits or other transmission
problems on the data link.
CRC
Number of packets received incorrectly having a CRC
error and a noninteger number of octets. On a serial
line, this is usually the result of noise or other
transmission problems.
frame
Number of times the serial receiver hardware was
unable to pass received data to a hardware buffer
because the input rate exceeded the receiver
’
s capacity
for handling the data.
overrun
Number of received packets ignored by the interface
because the interface hardware ran low on internal
buffers. These buffers are different than the system
buffers mentioned previously in the buffer description.
Broadcast storms and bursts of noise can cause the
ignored count to be incremented.
ignored
Number of times the watchdog receive timer expired.
watchdog
Number of multicast packets received.
multicast
Total number of messages transmitted by the system.
packets output
Total number of bytes, including data and MAC
encapsulation, transmitted by the system.
bytes (output)
Number of times that the far-end transmitter has been
running faster than the near-end Device
’
s receiver can
handle.
