# Ignore CI classes

To ignore some configuration item \(CI\) classes, for example Load Balancer \[cmdb\_ci\_lb\], when running CI Lookup Rules, set the **ignoreCIClass** \[**sn\_sec\_cmn.ignoreCIClass**\] system property.

## Before you begin

Role required: admin

**Note:**

The **ignoreCIClass** system property is available starting with Vulnerability Response v9.0, however, the property functionality is not available on upgrade from any previous version.

If you have upgraded from any Security Operations application, prior to version 9.0, see [KB0788209](https://support.servicenow.com/kb_view.do?sysparm_article=KB0788209) for instructions on how to enable this functionality.

## Procedure

1.  Enter `sys_properties.list` in the left navigation bar.

2.  Select **Enter**.

3.  In the **Search** menu, under **Name** enter `sn_sec_cmn.ignoreCIClass`.

4.  In the **Value** text box, enter the CI classes to exclude in a comma-separated list.

    \[Omitted image "ignoreCIClass.png"\] Alt text: ignoreCI Class system property example.

5.  Select **Update**.

    This list is used by CI Lookup Rules during the next import. Vulnerable items created during import are not associated to a CI of any type listed in the **Value** field of the `sn_sec_cmn.ignoreCIClass` system property.
