- .TH VARIABLES 5 "17 September 1989"
- .UC 4
- .SH NAME
- variables - Format of specifying variable names to SNMP tools.
- .SH SYNOPSIS
- system.sysdescr.0
- .SH 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.
- .br
- 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:
- .PP
- .I 1.1.0 system.sysDescr.0 and 1.sysDescr.0
- .PP
- all refer to the same variable name. Likewise:
- .PP
- .I .1.3.6.1.2.1.1.1.0 .iso.org.dod.internet.mgmt.mib.system.sysdescr.0 .1.3.6.1.2.1.1.sysdescr.0
- .PP
- All refer to the same variable name.
- .PP
- The description of the variables in the MIB is given in a file named
- .I "mib.txt"
- in the current directory or in a file named in the environment variable
- .I "MIBFILE" or in
- .I "/etc/mib.txt".
- These files are searched in the above order. The files are in the ASN.1 notation and use the
- OBJECT TYPE macro defined in RFC 1065. Most of the file describing the RFC 1066 MIB is pulled
- out of RFC 1066 without change.
- .SH "SEE ALSO"
- RFC 1065, RFC 1066, RFC 1067, ISO IS 8824(ASN.1)
- .SH BUGS
- The parser of the
- .I "mib.txt"
- file is not expected to handle bizarre (although correct) interpretations of the ASN.1 notation.
