Table 45 show interface dspfarm Field Descriptions (continued)

Field	Description
Giants	Number of packets that are discarded because they exceed the
	maximum packet size for the medium. For instance, any
	Ethernet packet that is greater than 1518 bytes is considered a
	giant.
Throttles	Number of times the receiver on the port was disabled, possibly
	because of buffer or processor overload.
Input errors	Number of packet input errors.
CRC	Cyclic redundancy checksum 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 itself. A high number of CRCs is usually the
	result of collisions or a station sending bad data. On a serial
	link, CRCs usually indicate noise, gain hits, or other
	transmission problems on the data link.
Frame	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.
Overrun	Number of times the serial receiver hardware was unable to
	hand received data to a hardware buffer because the input rate
	exceeded the ability of the receiver to handle the data.
Ignore	Number of received packets ignored by the interface because
	the interface hardware 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.
Packets output	Total number of messages sent by the system.
Bytes	Total number of bytes, including data and MAC encapsulation,
	sent by the system.
Underruns	Number of times that the far end transmitter has been running
	faster than the near-end router’s receiver can handle.
Output errors	Sum of all errors that prevented the final transmission of
	datagrams out of the interface being examined. Note that this
	value might not balance with the sum of the enumerated output
	errors; some datagrams can have more than one error, and
	others can have errors that do not fall into any of the specifically
	tabulated categories.
Collisions	Number of messages re-sent because of an Ethernet collision.
	Collisions are usually the result of an overextended LAN
	(Ethernet or transceiver cable too long, more than two repeaters
	between stations, or too many cascaded multiport transceivers).
	A packet that collides is counted only once in output packets.
