Description
You may receive an email alert if a router has invalid filter logic. This could be due to one of the following:
- Filter logic that doesn’t account for one or more filters. For example, you can’t add three filters to a router and set the filter logic to “1 OR 2”.
- Filter logic that references a nonexistent filter. For example, you can’t add two filters to a router and set the filter logic to “1 AND (2 OR 3)”.
- Filter logic that includes ANDs and ORs that are not separated by parenthesis. For example, you can’t set the filter logic to “1 AND 2 OR 3”. It would need to be “1 AND (2 OR 3)” or “(1 AND 2) OR 3”.
Resolution
To resolve this error, you’ll simply need to navigate to the router, click Manage Filters, and edit the filter logic to ensure it meets the requirements mentioned above.
