mibdirs DIRLIST
specifies a list of directories to search for MIB files. Note that this value can be overridden by the MIBDIRS environment variable, and the -M option.
mibs MIBLIST
specifies a list of MIB modules (not files) that should be loaded. Note that this list can be overridden by the MIBS environment variable, and the -m option.
mibfile FILE
specifies a (single) MIB file to load, in addition to the list read from the mibs token (or equivalent configuration). Note that this value can be overridden by the MIBFILES environment variable.
showMibErrors (1|yes|true|0|no|false)
whether to display MIB parsing errors.
commentToEOL (1|yes|true|0|no|false)
whether MIB parsing should be strict about comment termination. Many MIB writers assume that ASN.1 comments extend to the end of the text line, rather than being terminated by the next "--" token. This token can be used to accept such (strictly incorrect) MIBs. Note that this directive was previous (mis-)named strictCommentTerm, but with the reverse behavior from that implied by the name. This earlier token is still accepted for backwards compatibility.
mibAllowUnderline (1|yes|true|0|no|false)
whether to allow underline characters in MIB object names and enumeration values. This token can be used to accept such (strictly incorrect) MIBs.
mibWarningLevel INTEGER
the minimum warning level of the warnings printed by the MIB parser.
