smidiff(1) SMI Tools smidiff(1)NAMEsmidiff - check differences between a pair of SMI or SPPI modules
SYNOPSISsmidiff [ -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.
