This read-only true/false flag indicates whether data PDUs within a sequence on this session must arrive at continuously increasing addresses with no gaps or overlap (true, the default) or may arrive in any order (false). An admin reviews this negotiated setting when troubleshooting reassembly behavior or comparing session capabilities across different initiator/target combinations. For example, confirming this is true on a critical session reassures the admin that PDU reordering isn't a factor in an observed data-integrity investigation.
