LABEL	DESCRIPTION
RX
The following fields show detailed information about frames received.
InUnicasts	This field shows the number of good unicast frames received.
InBroadcasts	This field shows the number of good broadcast frames received.
InPause	This field shows the number of 802.3x Pause frames received.
InMulticasts	This field shows the number of good multicast frames received.
InGoodOctetsHi	This field shows the number of good upper octet frames received.
InGoodOctetsLo	This field shows the number of good lower octet frames received.
InFCSErr	This field shows the number of frames received with Cyclic
	Redundant Check (CRC) error(s).
InMACRcvErr	This field shows the number of frames received with an RxErr signal
	from the PHY.
InBadOctets	This field shows the number of bad octet frames received.
InUndersize	This field shows the number of frames received that were too short
	(shorter than 64 octets).
InFragments	This field shows the number of frames received that were too short
	(shorter than 64 octets) and were received with with Cyclical
	Redundancy Check (CRC) errors.
InJabber	This field shows the number of frames received with a length that
	exceeds the maximum octet size and were received with CRC errors.
InOversize	This field shows the number of frames received with a length that
	was out of range.
TX
The following fields show detailed information about frames transmitted.
OutUnicasts	This field shows the number of good unicast frames transmitted.
OutBroadcasts	This field shows the number of good broadcast frames transmitted.
Late	This is the number of times a late collision is detected, that is, after
	512 bits of the frames have already been transmitted.
Excessive	This is a count of frames for which transmission failed due to
	excessive collisions. Excessive collision is defined as the number of
	maximum collisions before the retransmission count is reset.
Multiple	This is a count of successfully transmitted frames for which
	transmission was inhibited by more than one collision.
Single	This is a count of successfully transmitted frames for which
	transmission is inhibited by exactly one collision.
Deferred	This is a count of frames for which transmission delayed due to busy
	traffic. The deferred frames are waiting to be transmitted from the
	MES-2110 buffer. This counter only works for the half-duplex mode.
RX+TX
64 Octets	This field shows the number of frames (including bad frames)
	received that were 64 octets in length.
65to127 Octets	This field shows the number of frames (including bad frames)
	received that were between 65 and 127 octets in length.
