IEEE 802.3 (64 bytes including the CRC) received on the port.
Oversize Frames
Number of frames exceeding the maximum specified by IEEE 802.3
(1518 bytes including the CRC) received on the port.
Fragments
Number of undersized frames, frames with alignment errors, and
frames with frame check sequence (FCS) errors (CRC errors)
received on the port.
