Telnet Provides command line access to CMC through the network.
The RACADM command line interface and the connect
command, 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.
SNMP Simple Network Management Protocol (SNMP) is a set of
protocol definitions for managing devices on the networks. The
CMC provides access to SNMP, which allows you to use SNMP
tools to query the CMC for Systems Management information.
The CMC MIB file can be downloaded from the CMC Web
interface, go to Chassis OverviewNetworkServices
SNMP. See the Dell OpenManage SNMP Reference Guide for
more information about the CMC MIB.
The following example show how the net-snmp snmpget
command can be used to get the chassis service tag from the
CMC.
snmpget -v 1 -c <CMC community name> <CMC IP
address>.1.3.6.1.4.1.674.10892.2.1.1.6.0
WSMan The WSMan Services is based on the Web Services for
Management (WSMan) protocol to perform one-to-many
systems management tasks. You can 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 script the WSMan 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 WSMan 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.
NOTE: The SSL port used for transport security is the
same as the CMC HTTPS port.
