♦ 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.
