Collect and organize managed IP device information using the SNMP protocol

You can connect your Splunk Edge Hub OS to IP devices and collect and organize information about these devices on a network using the Simple Network Management Protocol (SNMP) protocol. You can use the SNMP protocol to make a connection to devices that support this protocol.

Here's how to configure your Splunk Edge Hub OS to use the SNMP protocol to connect to IP devices:

Prerequisites

Before connecting your Splunk Edge Hub OS to an IP device, register your Splunk Edge Hub device and launch the Edge Hub Advanced Settings page.

1. Register your Splunk Edge Hub device. See Register or unregister your Splunk Edge Hub.
2. Complete the steps at Access the Edge Hub Advanced Settings page.

Steps

Connect your Splunk Edge Hub OS to an IP device using SNMP protocol:

1. In the Edge Hub Advanced Settings page, navigate to the SNMP tab.
2. Select Create.
3. Enter the IP address of the SNMP device.
4. Set the appropriate SNMP version, credentials and port. The default port is 161.
5. Add the MIB file provided by Splunk. If you don't have the MIB file from Splunk, you can upload your own.
   The Splunk Edge OS may have dependencies that might not be present on your device. Splunk Edge OS attempts to download the dependencies from external repositories. However if you're using the Edge Hub device in an air-gapped environment, Splunk Edge OS might not be able to reach the external repositories, resulting in time out errors. In an air-gapped environment, upload dependency-related MiB files from the MiB file.
   
6. Search for and select the the desired object identifier using the search field. You can search across names, descriptions, and symbolic names to choose which metrics to gather from the SNMP device.
7. Select Save.

Splunk Edge Hub OS pulls data from the device you have connected. You can search for the SNMP data in the Search and Reporting app using the following Search Processing Language (SPL) search:

index=edge-hub-snmp hub_name=<Edge Hub name> sourcetype=edge_hub

Download your SNMP configuration and upload it to another Splunk Edge Hub device

After completing a SNMP configuration for external sensors, you can download a configuration file to use it with other Splunk Edge Hub devices. Update the configuration file to replace values that are applicable to other Splunk Edge Hub devices, such as IP address, port, or SNMP version.

Downloading and uploading a configuration file means you don't have to repeat the configuration steps again for multiple Splunk Edge Hub devices.
