• Undersize – The total number of frames received that were less than 64 octets long (excluding framing bits, but
including FCS octets) and were otherwise well formed.
• Oversize – The total number of frames received that were longer than 1518 octets (excluding framing bits, but
including FCS octets) and were otherwise well formed.
• Fragments – The total number of frames received that were less that 64 octets in length (excluding framing
bits, but including FCS octets) and had either an FCS or an alignment error.
• Jabbers – The total number of frames received that were longer than 1518 octets (excluding framing bits, but
