Total frames received with a length of more than MaxSize octets but with a valid FCS. Total frames received with a length of more than MaxSize Octets but with an invalid FCS. Total frames received with an RxErr signal from the PHY. This includes 10 GE MAC Termination Errors. Total frames received with a CRC error not counted in Rx - Fragments, Rx - Jabber or Rx - RxErr. The total number of successfully transmitted frames that experienced no collisions but are delayed because the medium was busy during the first attempt. This counter is applicable in half-duplex only. The number of collision events seen by the MAC not including those counted in Single, Multiple, Excessive, or Late. This counter is applicable in half-duplex only. The total number of successfully transmitted frames that experienced exactly one collision. This counter is applicable in half-duplex only. The total number of successfully transmitted frames that experienced more than one collision. This counter is applicable in half-duplex only. The number frames dropped in the transmit MAC because the frame experienced 16 consecutive collisions. This counter is applicable in half-duplex only. The number of times a collision is detected later than 512 bits-times into the transmission of a frame. This counter is applicable in halfduplex only. The number of frames transmitted with an invalid FCS. Whenever a frame is modified during transmission (e.g., to add or remove a tag) the frame's original FCS is inspected before a new FCS is added to a modified frame. If the original FCS is invalid, the new FCS is made invalid too and this counter is incremented. This can occur because frames with a bad FCS are allowed into the switch. Total frames received and/or transmitted with a length of exactly 64 octets, including those with errors. Total frames received and/or transmitted with a length of between 65 and 127 octets inclusive, including those with errors. Total frames received and/or transmitted with a length of between 128 and 255 octets inclusive, including those with errors.

to view CLI commands which correspond to the web page entries
described above.
Rx - Fragments
Total frames received with a length of less than 64 octets and an invalid
FCS.
Rx - Oversize
Total frames received with a length of more than MaxSize octets but
with a valid FCS.
Rx - Jabber
Total frames received with a length of more than MaxSize Octets but
with an invalid FCS.
Rx - RxErr
Total frames received with an RxErr signal from the PHY. This includes
10 GE MAC Termination Errors.
Rx - FCSErr
Total frames received with a CRC error not counted in Rx - Fragments,
Rx - Jabber or Rx - RxErr.
Tx - Deferred
The total number of successfully transmitted frames that experienced
no collisions but are delayed because the medium was busy during the
first attempt. This counter is applicable in half-duplex only.
Tx - Collisions
The number of collision events seen by the MAC not including those
counted in Single, Multiple, Excessive, or Late. This counter is
applicable in half-duplex only.
Tx - Single Collision
The total number of successfully transmitted frames that experienced
exactly one collision. This counter is applicable in half-duplex only.
Tx - Multiple Collisions
The total number of successfully transmitted frames that experienced
more than one collision. This counter is applicable in half-duplex only.
Tx - Excessive Collisions
The number frames dropped in the transmit MAC because the frame
experienced 16 consecutive collisions. This counter is applicable in
half-duplex only.
Tx - Late
The number of times a collision is detected later than 512 bits-times
into the transmission of a frame. This counter is applicable in half-
duplex only.
Tx - FCSErr
The number of frames transmitted with an invalid FCS. Whenever a
frame is modified during transmission (e.g., to add or remove a tag) the
frame's original FCS is inspected before a new FCS is added to a
modified frame. If the original FCS is invalid, the new FCS is made
invalid too and this counter is incremented. This can occur because
frames with a bad FCS are allowed into the switch.
All - 64 Octets
Total frames received and/or transmitted with a length of exactly 64
octets, including those with errors.
All - 65-127 Octets
Total frames received and/or transmitted with a length of between 65
and 127 octets inclusive, including those with errors.
All - 128-255 Octets
Total frames received and/or transmitted with a length of between 128
and 255 octets inclusive, including those with errors.
All - 256-511 Octets
Total frames received and/or transmitted with a length of between 256
and 511 octets inclusive, including those with errors.
All - 512-1023 Octets
Total frames received and/or transmitted with a length of between 512
and 1023 octets inclusive, including those with errors.
All - 1024-Max Octets
Total frames received and/or transmitted with a length of between 1024
and MaxSize octets inclusive, including those with errors. MaxSize (the
jumbo frame size) is 10240 bytes.
