The IP addresses of the systems to be discovered can be included in an XML comment as shown above so
that it can be maintained at the same time as the XML file and copied and pasted into the Ping inclusion
ranges, system (hosts) names, templates, and/or hosts files field when creating or editing a discovery
task. See “Creating a new discovery task” for creating a new discovery task and see “Editing a discovery
task” for more information about editing a task.
After the XML file is created it can then be imported into HP Systems Insight Manager (HP SIM) prior to
running discovery using the following CLI command:
mxnodesecurity -a -f <path-to-xml-file>
HP recommends limiting the WBEM user name and password pairs to 10 to reduce the overall discovery
run time.

Global protocols
Managing a network is complex, and network management becomes even more complicated without
standards. When an organization purchases multiple management tools, each with a different method of
managing a particular hardware or software product, it must maintain and train network administrators in
different tools. This process is both expensive and inefficient. To address this issue, standards committees
have developed protocols for network management.
HP Systems Insight Manager (HP SIM) takes advantage of many different management protocol standards.
This capability enables HP SIM to provide management support for a wide array of manageable devices.
SNMP
The Internet Engineering Task Force (IETF), the standards-rating body for the worldwide Internet, has defined
a management protocol, SNMP , which has accumulated a major share of the market and has the support
of over 20,000 different products. SNMP has its roots in the Internet community. The complexity of large
international TCP/IP networks has provided the necessary incentive to develop a standard method of managing
devices on the network.
Within the SNMP framework, manageable network devices (routers, bridges, servers, and so on) contain a
software component called a management agent. The agent monitors the various subsystems of the network
element and stores this information in a Management Information Base (MIB). The agents enable the device
to generate traps, which can be configured to be sent to a trap destination server that is running HP SIM.
Conceptually, the MIB is a database that can be written to and read by a management application using
the SNMP protocol. There are two types of MIBs:
• Internet Management MIBs. These MIBs, standardized by the Internet community, include MIB-II,
Remote Monitoring (RMON), and others and represent the core objects that are common across the
