Open the capture file in Wireshark. Its Diameter dissector has been improved over the years to better handle and highlight these errors. For example, a fix was made so that when an AVP has the wrong length for its type, the dissector returns a NULL label instead of an uninitialized value, which prevents crashes and provides clearer feedback. avp14m incorrect length

To prevent the "AVP14M incorrect length" issue or minimize its impact:
If the cable is secure but the testing equipment reports an incorrect length, the internal conductors are likely not reaching the crimp/solder pins correctly. Share public link Open the capture file in Wireshark
When a Diameter node encounters an error, it should send back a response message that includes a Failed-AVP AVP. This special AVP contains the offending AVP (or a copy of its header) that caused the error. Checking the Failed-AVP in the error response will directly show you which AVP triggered the length mismatch, greatly accelerating the debugging process.
An AVP has a defined structure that includes a header and a data payload. The header contains fields like the AVP Code (identifying the attribute) and the field. This length field is crucial as it specifies the total size of the AVP in octets (bytes), including the header and its data.
This mismatch is officially termed and assigned the error code 5014 in the Diameter protocol specifications. The error can arise in two distinct ways:
. They cut the expected size of four specific ROMs (including avp14m ) in half to exactly .
