5-minute input rate,
5-minute output rate
Average number of bits and packets sent per second in the last 5 minutes.
packets input Total number of error-free packets received by the system.
bytes Total number of bytes, including data and MAC encapsulation, in the
err
or-free packets received by the system.
no buffer Number of received packets discarded because there was no buffer space in
t
he main system. Compare with ignored count. Broadcast storms on
Ethernet systems and bursts of noise on serial lines are often responsible for
no input buffer events.
broadcasts Total number of broadcast or multicast packets received by the interface.
runts Number of packets that are discarded because they are smaller than the
m
edium’s minimum packet size.
giants Number of packets that are discarded because they exceed the medium’s
max
imum packet size.
input errors Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored and
ab
ort counts. Other input-related errors can also increment the count, so that
this sum may not balance with other counts.
CRC Cyclic redundancy checksum generated by the originating LAN station or
fa
r-end device does not match the checksum calculated from the data
received.
On a LAN, this usually indicates noise or transmission problems on the
L
AN interface or the LAN bus. A high number of CRCs is usually the result
of traffic collisions or a station sending bad data.
On a serial link, CRCs usually indicate noise, gain hits, or other
t
ransmission problems on the data link.
frame Number of packets received incorrectly having a CRC error and a
n
oninteger number of octets.
overrun Number of times the serial receiver hardware was unable to hand received
da
ta to a hardware buffer because the input rate exceeded the receiver’s
ability to handle the data.
ignored Number of received packets ignored by the interface because the interface
h
ardware ran low on internal buffers. These buffers are different from the
system buffers mentioned previously in the buffer description. Broadcast
storms and bursts of noise can cause the ignored count to be incremented.
abort Illegal sequence of one bits on the interface. This usually indicates a
c
locking problem between the interface and the data-link equipment.
packets output Total number of messages sent by the system.
bytes Total number of bytes, including data and MAC encapsulation, sent by the
sy
stem.
underruns Number of times that the sender has been running faster than the router can
h
andle data. This condition may never be reported on some interfaces.
