2.
Modem state –
shows if the modem is operating correctly;
3.
Clear statistics –
resets all statistics counters (not available for “guest” account);
4.
Truncated frames
– number of truncated received frames;
5.
Long events
– frames having byte count greater than MAXIMUM FRAME SIZE
parameter (1518, 1536 or 1916 bytes);
6.
Vlan tags detected –
VLAN tagged frames;
7.
Unsup. opcodes
– frames recognized as control frames but contained an Unknown
Opcode;
8.
Pause frames
– frames received are control frames with valid PAUSE opcodes;
9.
Control frames
– frames received as control frames;
10.
Dribble nibbles –
indicates that following the end of the packet additional 1 to 7 bits
are received. A single nibble, named the dribble nibble, is formed but not sent to
the system;
11.
Broadcasts
– packets, which destination address contained broadcast address;
12.
Multicasts
– packets, which destination address contains multicast address;
13.
Dones
– reception of packets successfully completed;
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 ‘loss 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;
