Ethernet Error Statistics
n Buffer Full Frames Lost: Number of frames lost due to a lack of
receiver buffer space in the unit.
n CRC Errors: Number of frames received with an invalid CRC.
n Collisions: Number of times a collision occurred while the frame
was being received. This would indicate a hardware problem with an
Ethernet node on the infrastructure.
Ethernet node on the infrastructure.
n Frame Alignment Errors: Number of frames received whose size
in bits was not a multiple of 8. Occasionally, extra bits of data are
inadvertently attached to a transmitted packet causing a frame align-
ment error.

n Over-length Frames: Number of frames received that are longer
than the configured maximum packet size.
n Short Frames: Number of frames received that are shorter than the
