Ethernet Output — The following table describes Ethernet output fields.
Label Description
Broadcast Pckts
The number of packets, delivered by this sub-layer to a higher (sub-)
layer, which were addressed to a broadcast address at this sub-layer.
The total number of packets that higher-level protocols requested be
transmitted, and which were addressed to a multicast address at this
sub-layer, including those that were discarded or not sent.
For a MAC layer protocol, this includes both Group and Functional
addresses.
Multicast Pckets
The number of packets, delivered by this sub-layer to a higher (sub-)
layer, which were addressed to a multicast address at this sub-layer.
For a MAC layer protocol, this includes both Group and Functional
addresses. The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a multicast
address at this sub-layer, including those that were discarded or not
sent. For a MAC layer protocol, this includes both Group and Func-
tional addresses.
Undersize Pckets
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 Pckts
The total number of packets received that were longer than can be
accepted by the physical layer of that port (9900 octets excluding fram-
ing bits, but including FCS octets for GE ports) and were otherwise
well formed.
Collisions
The best estimate of the total number of collisions on this Ethernet seg-
ment.
Drop Events
The total number of events in which packets were dropped by the
probe due to lack of resources. Note that this number is not necessarily
the number of packets dropped; it is just the number of times this con-
dition has been detected.
CRC Align Errors
The total number of packets received that had a length (excluding
framing bits, but including FCS octets) of between 64 and 1518 octets,
inclusive, but had either a bad Frame Check Sequence (FCS) with an
integral number of octets (FCS Error) or a bad FCS with a non-integral
number of octets (Alignment Error).
Fragments
The total number of packets received that were less than 64 octets in
length (excluding framing bits but including FCS octets) and had either
a bad Frame Check Sequence (FCS) with an integral number of octets
(FCS Error) or a bad FCS with a non-integral number of octets (Align-
ment Error).
