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 exceeded the repeater count or cable length specified in the Fast Ethernet stan- dard.

♦Runt Frames. This statistic counts frames shorter than the 64-byte (octet) minimum defined by the Fast Ethernet standard. Runts are of- ten 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 packets received. Multicast events are messages sent from one node to multi- ple nodes on the segment.

♦Broadcast. This statistic counts the number of good broadcast pack- ets received. Broadcast events are messages sent to all nodes on the segment.

♦Auto Partitions. This statistic counts events where the port was par- titioned off from the rest of the network due to excessive collisions or cabling problems.

♦DRM (Data Rate Mismatch). This statistic counts events where there is a frequency mismatch between the received signal and the hub internal clock. A high count in this field may indicate a hardware

problem in the hub or in an Ethernet interface.
