NAME
       smidiff - check differences between a pair of SMI or SPPI modules

SYNOPSIS
       smidiff [ -Vhsm ] [ -c file ] [ -l level ] [ -i error-pattern ] [ -p module ] oldmodule newmodule

DESCRIPTION
       The  smidiff 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.

       Note that conformance statements are currently not checked.

       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.

OPTIONS
       -V, --version
              Show the smidump version and exit.

       -h, --help
              Show a help text and exit.

       -s, --severity
              Show the error severity in brackets before error messages.

       -m, --error-names
              Show the error names in braces before error messages.

       -c file, --config=file
              Read file instead of any other (global and user) configuration file.

       -p module, --preload=module
              Preload the module module before reading the main module(s). This may be helpful if an  incomplete  main
              module misses to import some definitions.

       -l level, --level=level
              Report errors and warnings up to the given severity level. See the smilint(1) manual page for a descrip-
              tion of the error levels. The default error level is 3.

       -i prefix, --ignore=prefix
              Ignore all errors that have a tag which matches prefix.

       oldmodule
              The original module.

       newmodule
              The updated module.

       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 smi_config(3) for more details.
