Table 4-16 Show Interface Cable Command Field Descriptions (continued)

Field	Description
drops	Indicates the number of packets dropped due to a full
	queue
Five minute input rate	Average number of bits and packets transmitted per second
Five minute output rate	in the last five minutes
packets input	Total number of error-free packets received by the system
bytes input	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 in the main system
Received broadcast	Total number of broadcast or multicast packets received by
	the interface
runts	Number of packets that are discarded because they are
	smaller than the medium’s minimum packet size
giants	Number of packets that are discarded because they exceed
	the medium’s maximum packet size
input errors	Includes runts, giants, no buffers, CRC, frame, overrun,
	and ignored counts
CRC	Indicates the number of times the cyclic redundancy
	checksum generated by the originating LAN station or
	far-end device does not match the checksum calculated
	from the data received
frame	Number of packets received incorrectly (with a CRC error
	and a non-integer number of octets)
overrun	Number of times the receiver hardware was unable to
	forward received data 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 hardware ran low on internal buffers
packets output	Total number of messages transmitted by the system
bytes	Total number of bytes, including data and MAC
	encapsulation, transmitted by the system
underruns	Number of times the transmitter ran faster than the
	receiving device could handle
output errors	Sum of all errors that prevented the final transmission of
	packets out of the interface being examined
interface resets	Number of times an interface has been completely reset
