Which parameter must the cluster administrator properly define when configuring an iSCSI logical interface in Data ONTAP 8.1 Cluster-Mode and later?

data-access is not a valid parameter in the network interface create command for LIF configuration in Data ONTAP Cluster-Mode.

data-address is not a valid LIF parameter; IP address configuration uses the separate 'address' and 'netmask' parameters.

The data-protocol parameter must be set to 'iscsi' when creating a LIF intended for iSCSI traffic so that Data ONTAP correctly classifies and configures the LIF for block-level protocol access. This parameter distinguishes iSCSI LIFs from other data LIF types such as NFS or CIFS. Without it, the cluster cannot enforce the correct protocol behavior or failover constraints for the LIF.

data-routing is not a valid parameter in LIF configuration; routing is handled via routing groups or default gateways separately.

A parameter is required - omitting data-protocol means the system cannot properly configure the LIF for iSCSI use, and iSCSI-specific constraints would not be applied.
