Description
managed system and uses the HTTPs channel. The –r option runs the
RACADM command over a network.
• Firmware RACADM is accessible by logging in to CMC using SSH or
Telnet. You can run the firmware RACADM commands without specifying
the CMC IP, user name, or password. After you enter the RACADM
prompt, you can directly run the commands without the racadm prefix.
Use the LCD on the front panel to:
• View alerts, CMC IP or MAC address, user programmable strings.
• Set DHCP.
• Configure CMC static IP settings.
Provides command line access to CMC through the network. The RACADM
command line interface and the connectcommand, which is used to connect to
the serial console of a server or IO module, are available from the CMC command
line.
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.
Use SSH to run RACADM 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 CMC and can be disabled.
The WSMAN Services is based on the Web Services for Management (WSMAN)
protocol to perform one-to-many systems management tasks. You must use WS-
MAN 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 script the WS-MAN interface.
WSMAN is a Simple Object Access Protocol (SOAP)–based protocol used for
systems management. CMC uses WS–Management 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 CMC WS-MAN implementation uses SSL on port 443 for transport security,
and supports basic authentication. The data available through WS-Management is
provided by CMC instrumentation interface mapped to the DMTF profiles and
extension profiles.

Web services interfaces can be utilized by leveraging client infrastructure, such
as Windows WinRM and Powershell CLI, open source utilities like WSMANCLI,
and application programming environments like Microsoft .NET.
