Description: This is a count of the number of good packets received by this port with a length field check error. A length check error occurs when the value in the length field is within the valid range for data length (3-1500 bytes) but does not match the actual data length of the packet. Length field values less than 46 bytes (which corresponds to the minimum legal packet size of 64 bytes) are not checked due to padding.
What is acdPortRxStatsLengthErrors?
This counts good packets where the declared length in the packet header doesn't match the actual data inside (for lengths 46-1500 bytes). Network engineers care about length errors because they can indicate application bugs, memory corruption, or hardware issues in the sending device. A value of 10 length errors per day might point to a misconfigured or failing device on your network.
