This object reports the identifier of this target port in the standardized identifier format appropriate for its transport type, complementing the plain-name form in ciscoScsiTgtPortName. Management tooling that needs the formal identifier construct - for cross-referencing against other identifier-keyed tables in this MIB - reads this field rather than the name field. As with the analogous initiator-side object, this distinction is mostly relevant to automated tooling rather than a human reading a report.
