14.
Jumbo frames
–
frame Type/Length field larger than 1518 (Type Field) bytes;
15.
Length check errors
– frame length field in the packet does not match the
actual data byte length and is not a Type Field;
16.
CRC errors
– frame CRC do not match the internally generated CRC;
17.
Code errors
– one or more nibbles are signalled as errors during reception of
the packet;
18.
False carrier errors
–
indicates that following the last received statistics
vector, a false carrier was detected, noted and reported with next received
statistics. The false carrier is not associated with this packet. False carrier is
activated on the receiving channel that does not result in a packet receive
attempt being made;
19.
Rx Dv event
– indicates that the last receiving event seen is too short to be a
valid packet;
20.
Prev. pkt dropped
– indicates that since the last RSV, a packet is dropped
(i.e. interframe gap too small);
21.
Byte counter
– total number of bytes received on the wire, not counting
collided bytes;
22.
FCS errors
–
number of generic framing procedure (GFP) frames with CRC
errors received by the de-encapsulation block;
23.
CHEC errors
– number of generic framing procedure (GFP) frames with
CHEC errors received by the de-encapsulation block;
24.
Dropped frames
– number of generic framing procedure (GFP) frames that
were dropped in the de-encapsulation block;
25.
Delineation errors
– number of „lost of synchronization‟ events;
26.
Vlan tags
–
number of VLAN tagged packets, 32-bit counter;
27.
Backpres. events
– carrier-sense-method backpressure was previously
applied;
28.
Pause frames
– frames transmitted are control frames with a valid PAUSE
opcodes;
29.
Control frames
– frames transmitted are control frames;
30.
Wire byte counter
–
total number of bytes transmitted on the wire, including
all bytes from collided attempts;
31.
Underruns
– underruns occur during frame transmission;
32.
Giants
– frames having byte count greater than the MAXIMUM FRAME SIZE
parameter (1516, 1536 or 1916 bytes);
33.
Late collisions
– Collisions occurred beyond the collision window (512 bit
times);
34.
Max collisions
–
packets aborted after number of collisions exceeded the
RETRANSMISSION MAXIMUM parameter;
35.
Excessive defers
– packets deferred in excess of 6,071 nibble times in 100
Mbps mode, or 24,287 bit-times in 10 Mbps mode;
36.
Non-exc. defers
– packets deferred for at least one attempt, but less than an
excessive defer;
37.
Broadcasts
– packets, which destination address contained broadcast
address;
38.
Multicasts
– packets, which destination address contained multicast address;
39.
Dones
– transmission of packets successfully completed;
40.
Length check errors
– frame length field in the packet does not match the
actual data byte length and is not a Type Field;
41.
CRC errors
– frame CRC do not match the internally generated CRC;
42.
Collisions
– number of collisions the current packet incurred during
transmission attempts. Note: bits 19 through 16 are the collision count on any
