Configure the elements that Discovery requires to investigate your network, such as credentials, schedules, and IP addresses.

## Configuration overview {#c_DiscoveryConfiguration__section_ghk_fyp_2cb}

Discovery can run on a regular, configurable schedule, or can be launched manually. The IP address ranges you provide tell Discovery which specific devices to investigate. To retrieve useful information, Discovery needs credentials for devices within a particular range, so that Discovery can connect to and run various probes on the devices it finds. Discovery compares the devices it finds with configuration items (CI) in the CMDB and updates any matching devices. If Discovery does not find a matching CI in the CMDB, it creates a CI.

## Discovery configuration procedures {#c_DiscoveryConfiguration__section_svt_yrp_2cb}

Use the following links to configure Discovery for your environment. You don't need to perform all these procedures to run a Discovery. The platform provides many defaults you can use to explore your network that are suitable for most discoveries. To get started quickly with Discovery, you can use Guided Setup, which expedites the setup of a basic Discovery.  

|-|-|-|
| [Discovery IP address configuration](https://servicenow-prod.fluidtopics.net/VTG3ViAAb~Fkcv0~y8pyjg "Use one or more of these methods in any combination to define the network or network segment for Discovery to query. You can include or exclude specific IP ranges from your query.") | [Discovery classifiers](https://servicenow-prod.fluidtopics.net/MvqMhodbwicG8cVoU5Q_CQ "A classifier tells Discovery which probes to trigger for the identification and exploration phases of discovery. Classifiers can also trigger the Horizontal Pattern probe, which launches a pattern, rather than additional probes, for identification and exploration.") | [Discovery status](https://servicenow-prod.fluidtopics.net/DspthDiBn~da7_tOJabX1Q "The Discovery status provides a summary of a Discovery launched from a schedule. You can also cancel a Discovery that is in progress from the status form.") |
| [Domain Separation and Discovery](https://servicenow-prod.fluidtopics.net/hYTOZGCwkFSNCcK7WdB6zw "Domain separation is supported in Discovery. Domain separation enables you to separate data, processes, and administrative tasks into logical groupings called domains. You can control several aspects of this separation, including which users can see and access data.") | [Discovery classification parameters](https://servicenow-prod.fluidtopics.net/MUt~FEg8Q5OS2Uhy_tjoIg "These parameters are available for Discovery classifiers.") | [Discovery Configuration Console](https://servicenow-prod.fluidtopics.net/X2pEFslt2KYIkLpE0_rr8g#c_DiscoveryConfigurationConsole "Use the Discovery Configuration Console to manage what kind of configuration items (CIs) and CI information you want to discover.") |
| [SNMP support for Discovery](https://servicenow-prod.fluidtopics.net/gQ4wxYjQCvP8T51ydsEbnQ#c_SNMPSupportForDiscovery "Discovery supports SNMP versions 1, 2c, and 3. If you have an active SNMP v3 credential, valid options for SNMP version are v3 or All. If you have an active SNMP v1 or v2 credential (community string), valid options for SNMP version are v1, v2c, or All. Default is All.") | [Discovery identifiers](https://servicenow-prod.fluidtopics.net/0wWWMC00zL4~MX8eHLAMvg "After Discovery classifies a configuration item (CI), it uses identifiers to determine if the device already exists in the CMDB.") |   |
| [Discovery and SCCM together](https://servicenow-prod.fluidtopics.net/3iZu6hzhqEUuy3GSJLTa8A#c_DiscoveryAndSCCMTogether "Use these guidelines to avoid common issues when you use Discovery and System Center Configuration Manager (SCCM) together.") | [Discovery properties](https://servicenow-prod.fluidtopics.net/6OmXtHd_W~setq24sqO8iw "Discovery properties allow you to control several aspects of the horizontal discovery process.") | [Discovery Home page](https://servicenow-prod.fluidtopics.net/M9rQk36hAXg5UIk3nXL6fw#discovery-home-page "The Discovery Home page provides a summary of discoveries that were triggered by cloud and non-cloud schedules. You can view any errors that occurred during a Discovery and find remediation suggestions. Use the Home page view to examine the cloud resources discovered for the service accounts you selected in a cloud schedule.") |
