Interface Description

Chassis LCD Panel 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.

Telnet 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.

SSH 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.

WS-MAN 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.

For client connection using Microsoft WinRM, the minimum required version is 2.0.
