Guide
Too long Frames
The number of frames received that exceed the maximum permitted
frame size.
Symbol Errors
For an interface operating at 100 Mb/s, the number of times there was
an invalid data symbol when a valid carrier was present
Sngl Collisions
The number of frames that are involved in a single collision, and are
subsequently transmitted successfully.
Mult Collisions
The number of frames that are involved in more than one collision and
are subsequently transmitted successfully.
Late Collisions
The number of times that a collision is detected later than one slot
Time into the transmission of a packet.
Excess Colli-
sions
The number of frames for which a transmission fails due to excessive
collisions.
Int MAC Tx Errs
The number of frames for which a transmission fails due to an internal
MAC sub-layer transmit error.
Int MAC Rx Errs
The number of frames for which a reception fails due to an internal
MAC sub-layer receive error.
Multicast Pckts
The number of packets, delivered by this sub-layer to a higher (sub-)
layer, which were not addressed to a unicast or broadcast address at
this sub-layer. The total number of packets that higher-level protocols
requested be transmitted, and which were not addressed to a unicast or
broadcast address at this sub-layer, including those that were discarded
or not sent.
Undersize Pckts
The total number of packets received that were shorter than 64 octets
(excluding framing bits, but including FCS octets) but were otherwise
well formed.
Oversize Pckts
The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) but 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 times that packets were detected as being dropped
due to a lack of resources (not necessarily the total number of packets
dropped).
CRC Align Errors
The total number of packets received that were between 64 and 1518
octets (excluding framing bits but including FCS octets) that 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).
