.SH DESCRIPTION

The \fBsmidiff\fP program is used to check differences between a pair

of SMI MIB modules or SPPI PIB modules.

E.g., it can be used to detect changes in updated MIB

modules that can cause interoperability problems with existing

implementations. SMIv1/v2 and SPPI style MIB/PIB modules are

supported.

.PP

Note that conformance statements are currently not checked.

.PP

Messages describing the differences are written to the standard output

channel while error and warning messages generated by the parser

are written to the standard error channel.

.SH OPTIONS

.TP

\fB-V, --version\fP

Show the smidump version and exit.

.TP

\fB-h, --help\fP

Show a help text and exit.

.TP

\fB-s, --severity\fP

Show the error severity in brackets before error messages.

.TP

\fB-m, --error-names\fP

Show the error names in braces before error messages.

.TP

\fB-c \fIfile\fB, --config=\fIfile\fP

Read \fIfile\fP instead of any other (global and user)

configuration file.

.TP

\fB-p \fImodule\fB, --preload=\fImodule\fP

Preload the module \fImodule\fP before reading the main

module(s). This may be helpful if an incomplete main module misses to

import some definitions.

.TP

\fB-l \fIlevel\fB, --level=\fIlevel\fP

Report errors and warnings up to the given severity \fIlevel\fP. See

the smilint(1) manual page for a description of the error levels. The

default error level is 3.

.TP

\fB-i \fIprefix\fB, --ignore=\fIprefix\fP

Ignore all errors that have a tag which matches \fIprefix\fP.

.TP

.I oldmodule

The original module.

.TP

.I newmodule

The updated module. 

.PP

If a module argument represents a path name (identified by containing

at least one dot or slash character), this is assumed to be the exact

file to read. Otherwise, if a module is identified by its plain module

name, it is searched according to libsmi internal rules. See

\fBsmi_config(3)\fP for more details.
