and priority can also be specified. DMI rules are specified by selecting a product name and at least one,
or at the most three, DMI elements with response values and compare rules.
Why add or modify system identification?
• You might have third-party systems on your network that are not included in the HP SIM database , and
you want them identified by unique product names based on location or use.
• You have systems of a known type that you want to identify in another way. For example, you have
laptops that you want to classify on some other basis.
Options for creating a System Type Manager rule
Systems are identified and classified using specific rules and are assigned a corresponding system type and
a product name.
For SNMP systems, STM uses the System object identifier and, optionally, a MIB variable OID and its value
and data type. Identification is based on the system object identifier returned from the system to be identified.
If there is a matching rule for the system object identifier, identification proceeds based on whether the
response value matches the criteria in the rule.
For DMI systems, STM uses requests consisting of one to three DMI elements, attribute, and value pairs. For
a rule to be applied, the returned response values must match values in the rule in a manner defined by the
corresponding compare rules.
The custom management page is a link on the System Page under the Tools & Links tab. The link appears
with other system links for the system if it is unique. You can specify a URL address that opens an HTML
page. For example, enter: http://support.networkingcompany.com/model123 .
New system types are displayed in system collections after a full discovery runs and identifies systems that
match rules you created.
You can modify and delete rules as the systems in your network change.

Creating STM rules
Perform this procedure to create a new SNMP rule through System Type Manager (STM).
The STM is a utility used to modify the default behavior of identification . STM enables you to customize the
type and product name of systems using rules based on responses to SNMP and DMI (Windows only)
collections from systems on your network.
NOTE: DMI rules can only be created from the command line.
NOTE: The following fields are required:
• System Object Identifier, including the Compare Rule
• System Type
• Product Name
To create a new SNMP rule:
1. Select Options→Manage System Types. The Manage System Types page appears.
2. Click New. The New rule section appears.
