EFID / ESID

OFTP2 file-end and session-end commands, RFC 5024.

Definition

EFID is sent by the Speaker after the last DATA block and carries the record count; the Listener replies with EFPA (persisted) or EFNA (error). ESID ends the session, either normally or with a reason code on abnormal termination.

Origin

Defined in RFC 5024 §5.3 (ODETTE File Transfer Protocol 2), maintained by Odette International.

Example in context

EFID recordcount=512 → EFPA; then ESID reason=normal → ESID echo → TCP close
