NAME

variables − variables format for snmpget(1), snmpwalk(1), and snmpnext(1)

SYNOPSIS

system.sysDescr.0

DESCRIPTION

SNMP variable names are specified in the format of ASN.1 Object Identifiers. Each variable represents an object specification in the Management Information Base (MIB), which is organized in a hierarchical tree-like manner.

Variables can be represented in several ways. Each variable name is given in the format of A.B.C.D..., where A, B, C, and D are subidentifiers in one of two forms of notation. Each subidentifier can be encoded as a decimal integer or as a symbolic name matching those listed in the following sections. Uppercase and lowercase letters in symbolic names are treated as equivalent.

Fully specified variables begin with a dot (.).

If there is no leading dot (.) in the variable name and if the first subidentifier is the symbolic name hp, the name is formed as if it was preceded with .iso.org.dod.internet.private.enterprises.

If there is no leading dot (.) in the variable name and if the first subidentifier is not the symbolic name hp, the name is formed as if it was preceded with iso.org.dod.internet.mgmt.mib.

Variables contain two portions. The first portion is the standardized specification of the variable (as in system.sysDescr). The second portion is an instance specification used to distinguish different instances of the object in the same MIB. If there can only be one instance, this part of the variable name is the subidentifier zero 0, (e.g., system.sysDescr.0). See RFC 1157 for more information on object instances.
