Stackable NWay Ethernet Switch User's Guide
Fragments The number of packets less than 64 bytes with
either bad framing or an invalid CRC. These are normally
the result of collisions.
Jabber The number of frames with length more than 1536
bytes and with CRC error or misalignment (bad framing).
Late Collision Counts collisions that occur at or after the
64 byte (octet) in the frame. This may indicate that delays
th
on your Ethernet are too long, and you have either exceeded
the repeater count or cable length specified in the Ethernet
standard.
MAC Rx Error Counts data errors detectable as 10BASE-
TX "symbol errors," bit patterns with illegal encodings. This
may indicate noise on the line.
The number of frames which are
Dropped Frames
dropped by this port since the last Switch reboot.
The number of frames detected that
Undersize Frames
are less than the minimum permitted frame size of 64 bytes
and have a good CRC. Undersize frames usually indicate
collision fragments, a normal network occurrence.
Total Errors The sum of the CRC Error, Oversize Frames,
Fragments, Jabber, Late Collision, MAC Rx Error, Dropped
Frames, and Undersize Frames counters.
The best estimate of the total number of
Collisions
collisions on this Ethernet segment.
