Described are techniques for automatically configuring target port settings. A set of target port settings of a target port of a data storage system is initialized in accordance with a first target port setting configuration. It is determined whether the data storage system supports host registration. If the data storage system supports host registration, first processing is performed that includes registering a first host with the data storage system, wherein registering includes sending first information from the first host to the data storage system, the first information being sent from an initiator port of the first host to the target port; determining, using the first information, whether the set of target port settings of the target port require modification for use by the first host; and modifying the set of target port settings in accordance with the first information if the set of target port settings require modification.
