Description
Type of Address Resolution Protocol configured for the
interface.
Number of hours, minutes, and seconds an ARP cache entry
will stay in the cache.
Number of hours, minutes, and seconds since the last packet
was successfully received/transmitted by the interface.
Number of hours, minutes, and seconds since the interface was
last reset because of a transmission that took too long. When the
number of hours in any of the "Last..." fields exceeds 24, the
number of days and hours is displayed. If the field overflows,
asterisks are printed.
Time at which the counters that measure cumulative statistics
(such as number of bytes transmitted and received) shown in
this report were last reset to zero. Note that variables that might
affect routing (for example, load and reliability) are not cleared
when the counters are cleared.
*** indicates the elapsed time is too large to be displayed.
0:00:00 indicates the counters were cleared more than 2
milliseconds (and less than 2
Type of queueing strategy in effect on the interface.
Number of packets in the output queue followed by the size of
the queue and the number of packets dropped due to a full
queue.
Number of packets in the input queue followed by the size of
the queue and the number of packets dropped due to a full
queue.
Average number of bits and packets received and transmitted
per second in the last 5 minutes. If the interface is not in
promiscuous mode, it senses network traffic it sends and
receives (rather than all network traffic).
The 5-minute input and output rates should be used only as an
approximation of traffic per second during a given 5-minute
period. These rates are exponentially weighted averages with a
time constant of 5 minutes. A period of four time constants
must pass before the average will be within two percent of the
instantaneous rate of a uniform stream of traffic over that
period.
Total number of error-free packets received by the system.
Total number of bytes, including data and MAC encapsulation,
in the error-free packets received by the system.
Number of received packets discarded because there was no
buffer space in the main system. Compare with ignored count.
Broadcast storms on Ethernet networks and bursts of noise on
serial lines are often responsible for no input buffer events.
