Configure an SNMP Agent via the User Interface

Required User Role: Administrator with Reuse my password for privileged tasks enabled

If your organization uses a Simple Network Monitoring Protocol (SNMP) network management station (NMS) for device monitoring, you can install a net-snmp agent onto Tenable Core to report device data to your NMS.

You can use the user interface to configure common SNMPv2c or SNMPv3 settings. To configure other advanced or uncommon SNMP settings, use the CLI as described in Configure an SNMP Agent via the CLI.

To install and configure an SNMP agent on Tenable Core via the user interface:

  1. Log in to Tenable Core via the user interface, as described in Log In to Tenable Core.

    The Tenable Core web user interface page appears.

  2. In the left navigation bar, click SNMP.

    If you already installed an SNMP agent on Tenable Core, the SNMP page appears. If you do not have an SNMP agent installed on Tenable Core, the Install SNMP Packages window appears.

  3. (Optional) In the Install SNMP Packages window, click Install SNMP to install the SNMP service.

    Tenable Core installs the SNMP service and opens inbound ports 161 and 162 on Tenable Core.

    The SNMP page appears.
