Managing SNMPv3 Trap Configuration

From Junos Space Platform Release 17.1R1 onward, you can modify the SNMPv3 trap configuration from the Junos Space Platform GUI. The Junos Space Network Management Platform stores the SNMPv3 trap configuration in the /opt/opennms/etc/trapd-configuration.xml file.

When a device is discovered using SNMPv3, Junos Space Platform sends the latest SNMPv3 trap configuration, which is the first item in the trapd-configuration.xml file, to the newly-discovered device. Modifications to SNMPv3 trap configuration trigger a restart of the OpenNMS and deployment of the latest configuration onto the devices.

The SNMPv3 trap configuration includes the username, security level, and authentication and privacy settings. Although you can configure multiple users, only the last modified user configuration is deployed onto the devices. The default username is JunosSpace. The security level for the JunosSpace user is by default set to authPriv.

Note:

After you upgrade Junos Space Platform to Release 17.1R1 or later, modify the SNMPv3 trap configuration from the Junos Space Platform UI or merge the old and new configuration as explained in Updating Network Monitoring After Upgrading the Junos Space Network Management Platform.

To modify the SNMPv3 trap configuration on the Junos Space Platform:

  1. On the Junos Space Platform UI, select Network Monitoring > Admin > SNMPv3 Trap Configuration.

    The SNMPv3 Trap Configuration page appears.

  2. In the User Name field, enter a unique username.

    authNoPriv

    Enables authentication without privacy settings. if you select this, you need to specify the authentication settings. The privacy settings remain disabled in the Platform UI.
    NoAuthNoPriv

    Disables both authentication and privacy settings. If you select this, you cannot configure authentication or privacy settings. The authentication and privacy settings remain disabled in the Platform UI.
  4. If you selected authPriv or authNoPriv from the Security Level list, configure the following authentication settings:
    Authentication Type

    Select MD5 or SHA.
    Authentication Password

    Type the authentication password for the user.

    Confirm Authentication Password

    Retype the authentication password to confirm.

    Note:

    These fields remain disabled if you selected NoAuthNoPriv from the Security Level list.
