CN30 Mobile Computer User's Manual
In short, SNMP is an application-layer protocol that facilitates the
exchange of management information between network devices. The
CN30 Mobile Computer is such an SNMP-enabled device. Use SNMP to
control and configure the CN30 Mobile Computer anywhere on an
SNMP-enabled network.
The CN30 Mobile Computer supports four proprietary Management
Information Bases (MIBs) and Intermec Technologies provides SNMP sup-
port for MIB-II through seven read-only MIB-II (RFC1213-MIB) Object
Identifiers (OIDs).
The Management Information Base is a database that contains information
about the elements to be managed. The information identifies the manage-
ment element and specifies its type and access mode (Read-Only, Read-
Write). MIBs are written in ASN.1 (Abstract Syntax Notation.1) — a
machine independent data definition language. Note: Elements to be man-
aged are represented by objects. The MIB is a structured collection of such
objects.
You will find the following MIB files either in the CN30 Mobile Manage-
ment Tools portion of the Intermec Developer's Library CD or on the web
via www.intermec.com:
• INTERMEC.MIB
• Defines the root of the Intermec MIB tree.
• ITCADC.MIB
• Defines objects for Automated Data Collection (ADC), such as bar
• code symbologies.
• ITCSNMP.MIB
• Defines objects for Intermec SNMP parameters and security methods,
• such as an SNMP security IP address.
• ITCTERMINAL.MIB
• Defines objects for CN30 Mobile parameters, such as key clicks.
Each object has a unique identifier called an OID, which consist of a
sequence of integer values represented in dot notation. Objects are stored in
a tree structure and OIDs are assigned based on the position of the object in
the tree. For example, the internet OID is equal to 1.3.6.1. Seven MIB
OIDs are shown in the following table:
