# Required Preconfiguration Tasks

This section describes the required tasks that must be completed before you configure SME.

This section includes the following topics:

• Enabling Clustering Using Device Manager

• Enabling SME

• Enabling DNS

• IP Access Lists for the Management Interface

• Creating and Assigning SME Roles and SME Users

• Installing DCNM-SAN and DCNM-SAN Client

• Adding a Fabric and Changing the Fabric Name

• Choosing a Key Manager

• Using FC-Redirect with CFS Regions

• Installing Smart Card Drivers

• SME Configuration Process

• SME Configuration Restrictions

Before configuring SME, you must explicitly enable clustering, SME, SSH, and DNS on the MDS switch with an installed MSM-18/4 module or on the MDS 9222i switch. By default, these are disabled. The configuration and verification operations for SME are only available when these are enabled on a switch.
