Frames received that were longer than 1518 bytes (without
VLAN tags) or 1522 bytes (with VLAN tags)
The number of times the receiver on the interface was disabled,
possibly because of buffer or CPU overload
Total number of packets received that had a normal length, but
contained checksum errors
Total number of frames that contained checksum errors and a
non-integer number of bytes
Number of times the receive rate of the interface exceeded the
capacity of the input queue, causing packets to be discarded
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)
Number of received packets ignored by the interface because
the interface hardware ran low on internal buffers
Total number of frames with parity errors
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
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 packets with errors
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.
Number of packets dropped because the interface ran low on
output buffers
Number of packets that failed to be transmitted due to causes
such as Ethernet collisions
Number of frames whose first transmission attempt was
delayed, due to traffic on the network media, and that were
successfully transmitted later
Number of times frames were delayed due to Ethernet
collisions detected during the transmission
