Applying Regular Expressions

Archive Search (SETTINGS menu > WhatsConfigured > 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 WhatsConfigured 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.
