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 description 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.
