Configuring Protocols to Send
Information to Dell OpenManage IT
Assistant
Dell™ OpenManage™ IT Assistant uses three systems management
protocols — Simple Network Management Protocol (SNMP), Common
Information Model (CIM), and Intelligent Platform Management Interface
(IPMI) over LAN. This appendix provides configuration information for
these protocols. SNMP and CIM allow IT Assistant to get status for the
Dell™ systems using server agents or Dell OpenManage Client
Instrumentation (OMCI). IPMI, however, does not require agents to retrieve
the status of the devices. It communicates with the baseboard management
controller (BMC) for information about devices.
This appendix includes procedures for configuring the systems management
protocols that support the discovery, status, and trap information. The
following table summarizes the availability of supported operating systems
and corresponding systems management protocols for systems that can be
managed by IT Assistant.
NOTE: The choice of protocols that you specify for discovering and managing the
devices can result in varying levels of manageability of the devices on your
network. For example, if you choose to manage devices on your network using only
the CIM protocol, the devices that have only SNMP agent (for example, DRAC) are
classified under Unknown. Consequently, you may not get the application launch
functionality (example RAC console) for these devices. To avoid such issues, make
a careful choice of the protocols, depending on the devices (and protocols
supported by agents running on those devices) that you will manage.
