Logical Module Representation
OOW Collisions
Displays the total number of Out Of Window (OOW) collisions detected on this
segment.
Opens the Segment Detail view. The Segment Detail view contains all the
information listed above as well as a button for Additional Statistics. The
Additional Statistics and the Segment Additional Detail button both
display 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 (MJLP) 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
Short Event MaxTime. Short Event MaxTime is greater than 74 bit times and
less than 82 bit times.
Rate Mismatches
Displays the number of occurrences of out of spec rate bits. This indicates the
number of times the FIFO buffer over-runs or under-runs due to transmission
rate errors.
Backoff Fails
Displays the number of times a frame was received on this port with collision
and port activity time of a value greater than 552 to 560 bit time.
Auto Partitions
Displays the number of times that this segment was auto-partitioned by the
hardware. This condition occurs when 32 consecutive collisions are detected
on the port.
Short IPGs
Displays the number of occurrences of too short Inter-Packet Gaps (IPGs)
before good packets detected.
Null Frames
Displays the total number of empty frames detected on this segment.
