> # Enabling iSCSI

> To use the iSCSI feature, you must explicitly enable iSCSI on the required switches in the fabric. Alternatively, you can enable or disable the iSCSI feature directly on the required modules using Cisco DCNM for SAN or Device Manager. By default, this feature is disabled in all switches in the Cisco MDS 9000 Family.

> Caution | When you disable this feature, all related configurations are automatically discarded.

> 1. Choose FC Services > iSCSI in the Physical Attributes pane.
