Table 2. Interfaces and protocols to access iDRAC (continued)
Interface or Protocol Description
NOTE: Telnet is not a secure protocol and is disabled by default. Telnet transmits all data,
including passwords in plain text. When transmitting sensitive information, use the SSH
interface.
SSH Use SSH to run RACADM and SMCLP commands. It provides the same capabilities as the Telnet console
using an encrypted transport layer for higher security. 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.
VMCLI Use the Virtual Media Command Line Interface (VMCLI) to access a remote media through the management
station and deploy operating systems on multiple managed systems.
SMCLP Use Server Management Workgroup Server Management-Command Line Protocol (SMCLP) to perform
systems management tasks. This is available through SSH or Telnet. For more information about SMCLP,
see Using SMCLP.
WSMAN
The LC-Remote Service is based on the WS-Management 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 and Python to
script to the WSMAN interface.
Web Services for Management (WSMAN) are 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.

iDRAC port information
The following ports are required to remotely access iDRAC through firewalls. These are the default ports iDRAC listens to for connections.
Optionally, you can modify most of the ports. To do this, see Configuring services.
