`/etc/mib.txt`

format for specifying variable names for SNMP utilities

The mib.txt file defines the format for specifying variable names for SNMP utilities. Each entry in the file is a variable name in ASN.1 notation for object identifiers, as defined in RFC 1065. The format is:

[.]A.B.C.D...

where A, B, C, D... are sub-identifiers in one of these forms:

a decimal integer
Or
a symbol as found in RFC 1066 MIB - the case of the symbols isn't significant

If you don't precede the variable name with a . (dot), SNMP utilities will add the prefix iso.org.dod.internet.mgmt.mib to the name. To fully specify the variable name, you must place a . (dot) before the first sub-identifier.

For example, the following refer to the same variable:

1.1.0 system.sysDescr.0 1.sysDescr.0 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

SNMP utilities search for a description of the variables in the following files, in this order:

mib.txt in the current directory
the file named in the MIBFILE environment variable
/etc/mib.txt
