Field

 

Description

 

 

 

 

 

 

5 minute input rate,

Average number of bits and packets transmitted per second in the

 

 

5 minute output rate

last 5 minutes. If the interface is not in promiscuous mode, it

 

 

 

 

senses network traffic that 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 2 percent of the

 

 

 

 

instantaneous rate of a uniform stream of traffic over that period.

 

 

 

 

Note The 5-minute period referenced in this output is a load

 

 

 

 

interval that is configurable under the interface. The

 

 

 

 

default value is 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 error-free packets received by the system.

 

 

 

 

 

 

 

no buffer

 

Number of received packets discarded because there was no

 

 

 

 

buffer space. Ignored Broadcast storms on Ethernet and bursts of

 

 

 

 

noise on serial lines are often responsible for no input buffer

 

 

 

 

events.

 

 

 

 

 

 

Received broadcasts

Number of broadcasts received.

 

 

 

 

 

 

 

runts

 

Number of packets that are discarded because they are smaller

 

 

 

 

than the minimum packet size of the medium. For instance, any

 

 

 

 

Ethernet packet that is less than 64 bytes is considered a runt.

 

 

 

 

 

 

 

giants

 

Number of packets that are discarded because they exceed the

 

 

 

 

maximum packet size of the medium. For example, any Ethernet

 

 

 

 

packet that is greater than 1518 bytes is considered a giant.

 

 

 

 

 

 

 

throttles

 

Number of times that the interface requested another interface

 

 

 

 

within the router to slow down.

 

 

 

 

 

 

 

input errors

 

Errors that include runts, giants, no buffer, cyclic redundancy

 

 

 

 

check (CRC), frame, overrun, and ignored counts. Other

 

 

 

 

input-related errors can also cause the input errors count to be

 

 

 

 

increased, and some datagrams may have more than one error;

 

 

 

 

therefore, this sum may not balance with the sum of enumerated

 

 

 

 

input error counts.

 

 

 

 

 

 

 

CRC

 

Errors created when the CRC generated by the originating LAN

 

 

 

 

station or far-end device does not match the checksum calculated

 

 

 

 

from the data received. On a LAN, such errors usually indicate

 

 

 

 

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 that is transmitting bad data.

 

 

 

 

 

 

 

frame

 

Number of packets received incorrectly that have a CRC error and

 

 

 

 

a non-integer number of octets. On a LAN, this error is usually the

 

 

 

 

result of collisions or a malfunctioning Ethernet device.
