About System Type Manager
Manufacturers assign unique OIDs to their SNMP-instrumented products. STM enables you to customize
identification by creating rules that map these OIDs to product categories and names of your choosing. HP
SIM discovers and applies information from the rule when an unknown system matches a rule that you specify.
Rules contain OIDs, and an optional, additional object identifier, that are compared with responses from a
target system . When a rule meets the comparison criteria, the system is identified using information from the
rule.
NOTE: SNMP rules can be created from the Manage System Types page of HP SIM or from the CLI
using the mxstm command. Additionally, on Windows systems, you can create rules based on the DMI
protocol using the CLI mxstm command in the CLI.
NOTE: SNMP rules require a OID and product name. Optionally, a compare rule (match or starts with),
MIB OID with value and compare rule, product type, subtype, custom management page, 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.
Reasons for adding or modifying system identification
• You might have third-party systems on your network that are not included in the HP SIM database , and
you want the systems 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 STM 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 OID and an optional MIB variable OID with its value and data
type. Identification is based on the system OID returned from the system to be identified. If there is a matching
rule for the system OID, 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 as 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 appear in system collections after a full discovery runs and identifies systems.
You can modify and delete rules as the systems change.
