Field 
Description 
giants 
Frames received that were longer than 1518 bytes (without 
VLAN tags) or 1522 bytes (with VLAN tags) 
throttles 
The number of times the receiver on the interface was disabled, 
possibly because of buffer or CPU overload 
CRC 
Total number of packets received that had a normal length, but 
contained checksum errors 
frame 
Total number of frames that contained checksum errors and a 
non-integer number of bytes 
- overruns 
Number of times the receive rate of the interface exceeded the 
capacity of the input queue, causing packets to be discarded 
aborts 
Total number of illegal packets received, including: 
Fragment frames: Frames that were shorter than 64 bytes 
(with an integral or non-integral length) and contained 
checksum errors 
Jabber frames: Frames that were longer than 1518 or 1522 
bytes and contained checksum errors (the frame lengths in 
bytes may or may not be integers) 
Symbol error frames: Frames that contained at least one 
undefined symbol 
Unknown operation code frames: Frames that were MAC 
control frames but not pause frames 
Length error frames: Frames whose 802.3 length fields did 
not match the actual frame lengths (46 bytes to 1500 bytes)
- ignored 
Number of received packets ignored by the interface because 
the interface hardware ran low on internal buffers 
- parity errors 
Total number of frames with parity errors 
Output (total): 0 packets, 0 bytes 
           0 broadcasts, 0 multicasts, 
0 pauses 
Packet statistics on the outbound direction of the interface, 
including the statistics of normal packets, abnormal packets, 
and normal pause frames, in packets and bytes 
Number of broadcast packets, multicast packets, and pause 
frames on the outbound direction of the interface 
Output (normal): 0 packets, - 
bytes           0 broadcasts, 0 
multicasts, 0 pauses 
Normal packet statistics on the outbound direction of the 
interface, including the statistics of normal packets and pause 
frames, in packets and bytes 
Number of broadcast packets, multicast packets, and pause 
frames on the outbound direction of the interface. 
output errors 
Output packets with errors 
- underruns 
Number of times the transmit rate of the interface exceeded the 
capacity of the output queue, causing packets to be discarded. 
This is a very rare hardware-related problem. 
- buffer failures 
Number of packets dropped because the interface ran low on 
output buffers 
aborts 
Number of packets that failed to be transmitted due to causes 
such as Ethernet collisions 
deferred 
Number of frames whose first transmission attempt was 
delayed, due to traffic on the network media, and that were 
successfully transmitted later 
collisions 
Number of times frames were delayed due to Ethernet 
collisions detected during the transmission
