Reading MIB Files
This section describes how to interpret the basic components of a MIB file. To determine the OIDs, view the
file snmp.h. For more information, see “SNMP File” on page27.
MIB files describe a specific component of a network device. The files are numerical strings that are
converted to ASCII text by the compiler of the SNMP manager. A word processor or text editor can be used
to open the ASCII file. The contents of an example ArubaOS enterprise MIB file, aruba-cts.my, are as
follows.
Opening Line
Following is the opening line, the beginning of the MIB file.
AI-AP-MIB DEFINITIONS ::= BEGIN
Imports

Inheritance
This section shows the vendor of the MIB and the inheritance, and provides an overall description.
A significant part of inheritance is the OID. The entire OID is not listed for each MIB object—instead, the
parent of the object is shown. The OID can be determined from the parent object as follows.
aiEnterpriseMibModules is the parent object —its OID is
1.3.6.1.4.1.14823.2.3.3.
aiStateGroup OBJECT IDENTIFIER ::= { aiMIB 2 }, the OID is
1.3.6.1.4.1.14823.2.3.3.1.2.
