Protocol functionality
The following table displays descriptions of management protocols displayed under Management Protocols
on the System Page which displays protocols that have responded when attempting to identify the system.
NOTE: The CMS initiates the requests for all protocols except events.
Functionality when enabledDescriptionManagement standard
System identification, inventory, eventsA common definition of management
information for systems, networks,
applications, and services.
CIM
System identificationA protocol using XML over HTTP to
exchange CIM information; part of the
WBEM suite of standards.
CIM-XML
System identification, inventory data, eventsDMI is an RPC-based protocol. To operate,
DMI requires opening a number of ports
through a firewall. DMI is not
recommended for use through firewalls. It
is largely being replaced by WBEM.
Note: DMI is used only for third-party
running Windows NT and for versions of
HP-UX earlier than to 11.0. WMI and
WBEM are used for more recent versions.
DMI
System identification, management tool
launch, agent configuration
HTTP and HTTPS
Provides system reachability (ping) check
during system discovery and before other
operations
ICMP is a required protocol tightly
integrated with IP. ICMP messages are
delivered in IP packets and are used for
out-of-band messages related to network
operation.
HP SIM can use ICMP messages to ping a
managed system. However, some routers
block ICMP messages so HP SIM provides
an alternative ping using TCP.
ICMP
System identification, inventory and eventsPart of the SNMP specification, the MIB is
a model of the information to be managed
through SNMP. It is equivalent to the CIM
defined by WBEM.
