Archive Search (SETTINGS > Configuration Management > Archive Search) applies a regular expression processing engine to your search results. This feature enables you to perform pattern matching or inverse pattern matching when managing archived configuration records.
Note: The Configuration Management regex engine uses
features and syntax similar to .NET/Perl 5.
Regular expression processing is a powerful compliment to archive search. You can leverage it for many tasks, for example:
- Returning only devices with a certain range of IP addresses.
- Pattern exclusion (Validating Subnet Changes).
- Checking a combination of values or settings that are important to site security and performance.
