Excessive Collisions A count of frames for which transmission on a particular interface fails due
to excessive collisions. This counter does not increment when the
interface is operating in full-duplex mode.
Single Collision Frames The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
Internal MAC Transmit Errors A count of frames for which transmission on a particular interface fails due
to an internal MAC sublayer transmit error.
Multiple Collision Frames A count of successfully transmitted frames for which transmission is
inhibited by more than one collision.
Carrier Sense Errors The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame.
SQE Test Errors A count of times that the SQE TEST ERROR message is generated by the
PLS sublayer for a particular interface.
Frames Too Long A count of frames received on a particular interface that exceed the
maximum permitted frame size.
Deferred Transmissions A count of frames for which the first transmission attempt on a particular
interface is delayed because the medium was busy.
Internal MAC Receive Errors A count of frames for which reception on a particular interface fails due to
an internal MAC sublayer receive error.
RMON Statistics
Drop Events The total number of events in which packets were dropped due to lack of
resources.
Jabbers The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either an FCS
or alignment error.
Received Bytes Total number of bytes of data received on the network. This statistic can
be used as a reasonable indication of Ethernet utilization.
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
Received Frames The total number of frames (bad, broadcast and multicast) received.
Broadcast Frames The total number of good frames received that were directed to the
broadcast address. Note that this does not include multicast packets.
Multicast Frames The total number of good frames received that were directed to this
multicast address.
CRC/Alignment Errors The number of CRC/alignment errors (FCS or alignment errors).
Undersize Frames The total number of frames received that were less than 64 octets long
(excluding framing bits, but including FCS octets) and were otherwise well
formed.
Oversize Frames The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise well
formed.
