variables - Format of specifying variable names to
SNMP tools.
SYNOPSIS
system.sysdescr.0
DESCRIPTION
Variable names are in the format of Object Identifiers
(ASN.1). There are several methods of representation.
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 may be encoded as a
decimal integer, or a symbol as found in the RFC1066 MIB.
The case of the symbols is not significant.
If there is no leading "." in the variable name, the name
will be formed as if having been preceded with
"iso.org.dod.internet.mgmt.mib.". A "." must be placed
before the first variable if the user is to fully specify
the name. For example:
1.1.0 system.sysDescr.0 and 1.sysDescr.0
all refer to the same variable name. Likewise:
.1.3.6.1.2.1.1.1.0 .iso.org.dod.internet.mgmt.mib.sys
tem.sysdescr.0 .1.3.6.1.2.1.1.sysdescr.0
All refer to the same variable name.
The description of the variables in the MIB is given in
the set of mib files defined by the MIBS environment vari
able (or the default list defined at compilation time) and
the mib files in the DATADIR/snmp/mibs directory (or the
MIBDIRS environment variable).

BUGS
The parser of the mib files file is not expected to handle
bizarre (although correct) interpretations of the ASN.1
notation.
