Table 3. 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.
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.
IPMITool Use the IPMITool to access the remote systems 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
Users Guide at dell.com/idracmanuals.
NOTE: IPMI version 1.5 is not supported.
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 on page 298.
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.
