♦ CRC AlignErrors (Pkts) Counts otherwise valid frames that did not end on a byte (octet) boundary. ♦ UndersizePkts (Pkts) Counts packets received that were less than 64 octets long (excluding framing bits, but including FCS octets) and were otherwise well formed. ♦ OversizePkts (Pkts) Counts packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets) and were otherwise well formed. ♦ Fragments (Pkts) Counts packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Errors). ♦ Jabbers (Pkts) Counts frames longer than the maximum 1518 bytes (octets) with either bad framing or an invalid CRC. ♦ Collisions (Pkts) Counts transmission collisions on the Ethernet segment. ♦ The Hub also collects packet distribution statistics categorizing Ethernet frames by length: • 64 Octs (Pkts) • 65-127 Octs (Pkts) • 128-255 Octs (Pkts) • 256-511 Octs (Pkts) • 512-1023 Octs (Pkts) • 1024-1518 Octs (Pkts) Utilization An Ethernet segment can be monitored using the Utilization display. 13
