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).
