Table 3. Interfaces and protocols to access iDRAC
Interface or Protocol Description
● You do not have to specify the iDRAC IP, user name, or password to run the firmware RACADM
commands. After you enter the RACADM prompt, you can directly run the commands without
the racadm prefix.
iDRAC RESTful API and
Redfish
The Redfish Scalable Platforms Management API is a standard defined by the Distributed
Management Task Force (DMTF). Redfish is a next-generation systems management interface
standard, which enables scalable, secure, and open server management. It is a new interface that
uses RESTful interface semantics to access data that is defined in model format to perform out-
of-band systems management. It is suitable for a wide range of servers ranging from stand-alone
servers to rack mount and bladed environments and for large scale cloud environments.
Redfish provides the following benefits over existing server management methods:
● Increased simplicity and usability
● High data security
● Programmable interface that can be easily scripted
● Follows widely-used standards

WSMan
The LC-Remote Service is based on the WSMan protocol to do one-to-many systems management
tasks. You must use WSMan client such as WinRM client (Windows) or the OpenWSMan client
(Linux) to use the LC-Remote Services functionality. You can also use Power Shell or Python to
script to the WSMan interface.
Web Services for Management (WSMan) is a Simple Object Access Protocol (SOAP)–based
protocol used for systems management. iDRAC uses WSMan to convey Distributed Management
Task Force (DMTF) Common Information Model (CIM)–based management information. The CIM
information defines the semantics and information types that can be modified in a managed system.
The data available through WSMan is provided by iDRAC instrumentation interface mapped to the
DMTF profiles and extension profiles.

SSH Use SSH to run RACADM commands. The SSH service is enabled by default on iDRAC. The SSH
service can be disabled in iDRAC. iDRAC only supports SSH version 2 with the RSA host key
algorithm. A unique 1024-bit RSA host key is generated when you power-up iDRAC for the first time.
IPMITool Use the IPMITool to access the remote system’s basic management features through iDRAC. The
interface includes local IPMI, IPMI over LAN, IPMI over Serial, and Serial over LAN. For more
information on IPMITool, see the Dell OpenManage Baseboard Management Controller Utilities
User’s Guide at dell.com/idracmanuals.
NOTE: IPMI version 1.5 is not supported.
NTLM iDRAC allows NTLM to provide authentication, integrity, and confidentiality to the users. NT LAN
Manager (NTLM) is a suite of Microsoft security protocols and it works in a Windows network.
SMB iDRAC9 supports the Server Message Block (SMB) Protocol. This is a network file sharing protocol
and the default minimum SMB version supported is 2.0, SMBv1 is no longer supported.
NFS iDRAC9 supports Network File System (NFS). This is a distributed filesystem protocol that
enables users to mount remote directories on the servers.
iDRAC port information
The following table lists the ports that are required to remotely access iDRAC through firewall. These are the default ports
iDRAC listens to for connections. Optionally, you can modify most of the ports. To modify ports, see Configuring services on
page 96.
