mib.defs File Format

Purpose

Provides descriptions of Management Information Base (MIB) variables for the snmpinfo command.

Description

The mib.defs file provides object descriptions of MIB variables for the snmpinfo command issued with the get, next, set, and dump options. See the snmpinfo command for more information. This command is part of Simple Network Management Protocol Agent Applications in Network Support Facilities.

The mib.defs file is not intended to be edited by the user. The file should be created with the mosy command. See the mosy command for information on how to create the mib.defs file. This file has the following format:

The MIB group fields are separated by spaces or tabs and contain the following information:

GroupDescriptor	Holds the textual name of the MIB group.
GroupEntry	Denotes the parent MIB group and the location of this MIB group in the parent group. This field is used by the snmpinfo command to resolve the ASN.1 dotted notation for MIB variables under this group.

The MIB groups are defined as follows:

Group Descriptor	Group Entry
internet	iso.3.6.1
directory	internet.1
mgmt	internet.2
.	.
.	.
.	.
mib-2	mgmt.1
system	mib-2.1
.	.
.	.

The object definitions of MIB variables are formatted as follows:

Object Descriptor	Group Entry	Syntax	Access	Status
sysDescr	system.1	DisplayString	read-only	mandatory

The MIB variable fields are separated by spaces or tabs, and contain the following information:

ObjectDescriptor	Holds the textual name of the object.
GroupEntry	Denotes the MIB object group and the location of this MIB variable in this group. This field is used by the snmpinfo command to resolve the ASN.1 dotted notation for this MIB variable.
Syntax	Denotes the type of the object as one of the following: INTEGER OCTET STRING or DisplayString OBJECT IDENTIFIER Network Address Counter Gauge TimeTicks Opaque
Access	Designates the access permissions for the object and can be one of the following: Read-only Read-write Write-only Not-accessible
Status	Designates the RFC 1213 compliance status of the object and can be one of the following: Mandatory Optional Deprecated Obsolete

The parent MIB group definition required for a particular MIB variable GroupEntry definition must precede the object definition for the MIB variable.

Comments begin with a # (pound sign) or - - (two dashes) and continue to the end of the line.
