? ?
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
th
byte (octet) in the frame. This may indicate that delays
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.
? ?
Dropped Frames The number of frames which are
dropped by this port since the last Switch reboot.
? ?
Undersize Frames
The number of frames detected that
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.
? ?
Collisions
The best estimate of the total number of
collisions on this Ethernet segment.
