5-40 TCP/IP Ethernet Communications User’s Manual – January 1996
GFK-1004B
Table 5-16. Data Link Tallies (part of Tally l)
Tally Meaning
Unreg Number of 802.3 frames received and discarded because the destination
LSAP was not configured in the node.
Lsap0 Number of frames received and discarded because the destination LSAP had
the value zero.
LsapOfl Number of LLC service requests rejected due to lack of LSAP table space. A
non-zero value in this tally indicates an Ethernet Interface system software
error and should be reported to GE Fanuc Automation immediately.
EthUnreg Number of Ethernet frames received and discarded because the destination
Protocol was not configured in the node..
MacErr A severe network fault prevented transmission of a frame for more than one
second. See Exception Log, Event c, Entry 2 = 10b.
BufProb A received LLC frame was lost due to the inability of the LLC software to
acquire a system buffer. This may indicate a memory configuration problem or
a temporary overload of traffic at the station.
UnrecPdu Number of 802.3 frames received and discarded because the LLC control field
is invalid.
TstRcvd Number of test frames received.
TstResp Number of test frame responses sent.
PadErr Number of frames received which had a padding and the padding was more
than 48 bytes.
Table 5-17. MAC Layer Tallies (part of Tally l)
Tally Meaning
SQEErr Number of times the SQE test failed.
MisdPack The number of packets a receiver lost due to a lack of receive buffers.
FrameErr The number of incoming packets that did not contain a multiple of eight bits.
SuccOne The number of times a successful transmission was made with exactly one retry.
CrcErr The number of incoming packets detected with a CRC error.
RbufErr The number of times the next buffer was unavailable while receiving a chained
data packet.
LateColl The number of times a collision occurred after the slot time of the
channel had elapsed.
LostCarr The number of times the carrier was lost during a transmission.
BsyCarr The number of times the transmitter had to wait because it sensed a busy carrier
signal.
NoRtry The number of times a successful transmission was made with no
retries needed.
SuccMore The number of times a successful transmission was made with more than one
retry.
FRtry The number of times the transmission failed despite using the maximum of 15
retries.
