snmpi - The extensible SNMP subagent data initializer
/usr/sbin/snmpi [-d] [-p] [-n prefix] [-e exclude_file]
defs_file {[-r] subtree}...
Specifies debug mode. Generates formatted output of the
internal tree of all MIB objects defined in defs_file.
This option is useful in identifying problems in MIB symbol
resolution. Specifies a prefix string to be prepended
to each variable generated by the snmpi program. Specifies
the name of a file that contains a list of MIB
objects that are not to be included in the emitted object
table initialization code created by the program. Specifies
the name of a MIB object identifier (OID) that
defines the base of the MIB subtree that will be registered
as a unit (with the snmpd daemon) by the subagent.
(The snmpd daemon will subsequently expect the subagent to
handle all MIB objects contained in the subtree.) Several
subtrees may be specified, and at least one is required
unless the -p option is used.
If the base MIB object identifier is not unique,
its name may be prefixed by its parents name, separated
by an underscore character (_); for example,
mn_system.
The subtree parameter may also contain the suffix
_tbl.h or _tbl.c to facilitate the use of snmpi
within makefiles.
For each subtree parameter specified, snmpi produces
the files subtree _tbl.h, subtree_tbl.c, and
subtree_tbl.txt.
If the optional -r option is specified, the OID
that defines the base of the MIB subtree is the
lower bound (OID of the first leaf object in the
MIB subtree) of the range of objects that make up a
MIB subtree row. The upper bound (OID of the last
leaf object in the MIB subtree) is contained in an
ESNMP_REG structure, subtree_reg, in the subtree_tbl.c
file. The snmpi program produces the
subtree_reg structure.
If you use the -r option, all objects in the MIB
subtree must be leaf objects occuring at the same
level. This means that the length of the OID for
each object defined in the MIB subtree must be the
same and that each object defined in the MIB subtree
must be a leaf object (OID length is the
same).
You can register the MIB subtree row by specifying
the ESNMP_REG structure as the parameter to the
esnmp_register2() routine. You can unregister the
MIB subtree row by specifying the generated
ESNMP_REG structure to the esnmp_unregister2() routine.
Specifies a mosy output file or a concatenation of mosy
output files.
The snmpi program emits subtree object table initialization
C code to be compiled and linked with the method routines
as part of an extensible SNMP subagent.

Originally, this work was partially supported by the U.S.
Defense Advanced Research Projects Agency and the Rome Air
Development Center of the U.S. Air Force Systems Command
under contract number F30602-88-C-0016. Marshall T. Rose
wrote the original (insecure) 4BSD/ISODE SNMP package.
David L. Partain of the Department of Computer and Information
Science at Linkoping University, Sweden added most
of the administrative facilities as a part of his Masters
work at the University of Tennessee, Knoxville. Dr. Jeffrey
D. Case of SNMP Research supervised his work, and
Keith McCloghrie of Hughes LAN Systems provided implementation
guidance.
Major modifications to the code were made as part of the
extensible SNMP Agent for Tru64 UNIX.
