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  lev‐
	      els. 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_con‐
       fig(3) for more details.
