NOTE:
HP SIM will not receive traps from the application using port 162 unless the application is configured
to forward traps to the port assigned to HP SIM.
NOTE:
If the SnmpTrapPortAddress entry is deleted, HP SIM will default to port 162.
SNMP communication between systems is used to gather information about a system. HP SIM attempts SNMP
communications based on the number of SNMP retries you specify and only stops when the communication
is successful or the number of retries is exceeded. HP SIM also waits for SNMP responses between retries,
based on the timeout period. Finally, HP SIM can only communicate through SNMP when the community
string specified on the system and the community string specified for that system in HP SIM match. The
community string, "public," is a commonly used default. However, you can specify any community string
needed for your security requirements.
NOTE:
Community strings on the managed system and the HP SIM community strings for the system must
match to manage the system through SNMP. Some SNMP management agents also provide IP address
filtering. Be sure the HP SIM IP address is in the allow list for any given SNMP agents.
DMI
The Desktop Management Task Force (DMTF), formed in 1992 and composed of leading PC industry vendors
and corporations, established a common, platform-independent process for specifying methods of managing
desktop hardware and software components. HP is a Steering Committee member of the DMTF and helped
to define the task force's two pieces of technology: the
(DMI) software and
the
(MIF) language. DMI software serves as the liaison between
desktop-resident management programs, manageable hardware, and software components on the computer.
DMI is most commonly used for obtaining information from desktops, but some HP servers and workstations
do support DMI.
HTTP
HP SIM also takes advantage of the industry-standard HTTP protocol (used to transfer information over the
World Wide Web) for transportation of management information. Many systems support some kind of
configuration "home page" that is supported over HTTP or the secure HTTPS protocol. HP SIM attempts to
find HTTPS servers running on systems if the Global Protocol Settings page has this enabled. See
for more information.
WBEM
Web-Based Enterprise Management
(WBEM) is one of the newest management protocols. This protocol
leverages the industry-standard Common Information Model (CIM) as defined by the DMTF. HP SIM can
communicate to systems directly using the WBEM protocol or to the Windows WMI systems using the WMI
Mapper Proxy. HP SIM uses WBEM to communicate with storage system
. HP has
been leading this effort through its association with the WBEM initiative. WBEM is an initiative supported
by HP, Microsoft, Intel, BMC, Cisco, and 120 other platform, operating system, and application software
suppliers.
When WBEM is enabled, the management console can obtain information from any
that supports
WBEM. For WBEM to work, the correct user name and password must be provided for the given system.
WBEM enables a larger set of server and storage manageability data to be collected and displayed on the
System Page
and in reports. The presence of WBEM enables the Properties pages and enables WBEM
indications (events) to be displayed in event collections. Without HTTP enabled, HP SIM will not discover
any web-based features on a system.
