Alignment
Displays the total number of misaligned packets detected on this segment.
FCS Errors
Displays the total number of frames received that are an integral number of
octets in length but do not pass the Frame Check Sequence (FCS).
Runts
Displays the total number of runt packets received by this segment. A runt
packet is one byte less than the standard Ethernet frame of 64 bytes, not
including preamble.
Giants
Displays the total number of giant packets received by this segment. A giant
packet exceeds 1518 bytes, not including preamble.
OOW Collisions
Displays the total number of Out Of Window (OOW) collisions detected on this
segment.
Selecting a segment and clicking this buttons opens the Segment Detail View
for that segment . The Segment Detail View displays graphs of the same
information displayed in the Ethernet Backplane Segment Statistics view,
described on page 2-7, as well as a button for Additional Statistics. The
Additional Statistics button opens the Additional Statistics view, which
provides graphs of the following information:
Bcast Frames
Displays the total number of broadcast frames detected on this segment.
Mcast Frames
Displays the total number of multicast frames detected on this segment.
TotalFragments
Displays the total number of fragmented frames detected on this segment.
Long Events
Displays the number of times that MAU jabber lockup protection was detected
due to transmission of data that exceeded 5 msec in duration (Octet count
greater than MaxFrame size). This information can be useful in identifying
faulty stations.
Short Events
Displays the number of fragments detected with Activity Duration less than a
minimum threshold value.
Rate Mismatches
Displays the number of times the FIFO buffer over-runs or under-runs due to
transmission rate errors.
