This OID reports the instantiation type (CucsVnicInstantiation) of the launched, deployed instance of an iSCSI vNIC as it actually runs on a server, as opposed to the vNIC's policy-level definition (IScsiLCP) — whether this vNIC instance was created from a template or defined independently. An admin cares because template-instantiated vNICs inherit changes automatically when the template is updated, while independently-created ones do not, which changes how config drift can happen. For example, an admin rolling out a new VLAN to a vNIC template would rely on this instType value to confirm which IScsiLCP instances are template-derived and will pick up the change automatically.
