♦
Short Events. This statistic counts events where less than 10 bytes
are received and the frame start delimiter is invalid, or where the
start frame delimiter is valid but less than 2 bytes are received. This
type of error may indicate noise on the line.
♦
Late Events. This statistic counts collisions that occur at or after
the 64th byte (octet) in the frame. A high count here may indicate
that delays on your Ethernet are too long, and you have either ex-
ceeded the repeater count or cable length specified in the Fast
Ethernet standard.
♦
Runt Frames. This statistic counts frames shorter than the 64-byte
(octet) minimum defined by the Fast Ethernet standard. Runts are
often caused by collisions.
♦
Collisions. This statistic counts collisions on the Ethernet segment.
♦
FCS Errors. This statistic counts otherwise valid frames that fail
the CRC check.
♦
Alignment Errors. This statistic counts otherwise valid frames that
did not end on a byte (octet) boundary.
♦
Readable Frames. This statistic counts valid frames.
♦
Multicast. This statistic counts the number of good multicast pack-
ets received. Multicast events are messages sent from one node to
multiple nodes on the segment.
♦
Broadcast. This statistic counts the number of good broadcast
packets received. Broadcast events are messages sent to all nodes on
the segment.
♦
Auto Partitions. This statistic counts events where the port was
partitioned off from the rest of the network due to excessive colli-
sions or cabling problems.
♦
DRM (Data Rate Mismatch). This statistic counts events where
there is a frequency mismatch between the received signal and the
