– 107 –
Deferred Transmissions A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium was busy.
Frames Too Long A count of frames received on a particular interface that exceed the
maximum permitted frame size.
Alignment Errors The number of alignment errors (missynchronized data packets).
FCS Errors A count of frames received on a particular interface that are an integral
number of octets in length but do not pass the FCS check. This count
does not include frames received with frame-too-long or frame-too-
short error.
SQE Test Errors A count of times that the SQE TEST ERROR message is generated by the
PLS sublayer for a particular interface.
Carrier Sense Errors The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame.
Internal MAC Receive Errors A count of frames for which reception on a particular interface fails due
to an internal MAC sublayer receive error.
Internal MAC Transmit
Errors
A count of frames for which transmission on a particular interface fails
due to an internal MAC sublayer transmit 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.
Fragments The total number of frames received that were less than 64 octets in
length (excluding framing bits, but including FCS octets) and had either
an FCS or alignment error.
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
Received Octets Total number of octets of data received on the network. This statistic
can be used as a reasonable indication of Ethernet utilization.
Received Packets The total number of packets (bad, broadcast and multicast) received.
Broadcast Packets The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
Multicast Packets The total number of good packets received that were directed to this
multicast address.
Undersize Packets The total number of packets received that were less than 64 octets long
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
Oversize Packets The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
64 Bytes Packets The total number of packets (including bad packets) received and
transmitted that were 64 octets in length (excluding framing bits but
including FCS octets).
