Abstract: In a data processing network, error detection information (EDI) is generated for first data of a first communication protocol of a plurality of communication protocols, the EDI including an error detection code and an associated validity indicator for each field group in a set of field groups. The first data and the EDI are sent through a network interconnect circuit, where the first data is translated to second data of a second communication protocol. An error is detected in the second data received from the network interconnect circuit when a validity indicator for a field group is set in EDI received with the second data and an error detection code generated for second data in the field group does not match the error detection code associated with the field group in the received EDI.
