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

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

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.

-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.

The libsmi(3) project is documented at http://www.ibr.cs.tu-bs.de/projects/libsmi/.
