Configure communities and destinations for SNMP alerts

Contributors

To configure Simple Network Management Protocol (SNMP) alerts, you must identify at least one server where the storage array’s event monitor can send SNMP traps. The configuration requires a community name and IP address for the server.

Before you begin
  • A network server must be configured with an SNMP service application. You need the network address of this server (either an IPv4 or an IPv6 address), so the event monitor can send trap messages to that address. You can use more than one server (up to 10 servers are allowed).

  • A community name must be created, consisting of only printable ASCII characters. The community name, which is a string that acts like a password for the network servers, is typically created by a network administrator. Up to 256 communities can be created.

  • The management information base (MIB) file has been copied and compiled on the server with the SNMP service application. This MIB file defines the data being monitored and managed.

    If you do not have the MIB file, you can obtain it from the NetApp Support site:

    • Go to NetApp Support.

    • Click Downloads.

    • Click Software.

    • Find your management software (for example, SANtricity System Manager), and then click Go! on the right.

    • ClickView & Download on the latest version.

    • Click Continue at the bottom of the page.

    • Accept the EULA.

    • Scroll down until you see MIB file for SNMP traps, and then click the link to download the file.

About this task

This task describes how to identify the SNMP server for trap destinations, and then test your configuration.

Steps
  1. Select Settings  Alerts.

  2. Select the SNMP tab.

    If a community is not yet configured, the SNMP tab displays "Configure Communities."

  3. Select Configure Communities.

    The Configure Communities dialog box opens.

  4. In the Community Name field, enter one or more community strings for the network servers, and then click Save.

    The Alerts page displays "Add Trap Destinations."

  5. Select Add Trap Destinations.

    The Add Trap Destinations dialog box opens.

  6. Enter one or more trap destinations, select their associated community names, and then click Add.

    • Trap Destination — Enter an IPv4 or IPv6 address of the server running an SNMP service.

    • Community name — From the drop-down, select the community name for this trap destination. (If you defined only one community name, the name already appears in this field.)

    • Send Authentication Failure Trap — Select this option (the checkbox) if you want to alert the trap destination whenever an SNMP request is rejected because of an unrecognized community name. After you click Add, the trap destinations and associated community names appear in the SNMP tab of the Alerts page.

  7. To make sure a trap is valid, select a trap destination from the table, and then click Test Trap Destination to send a test trap to the configured address.

Results

The event monitor sends SNMP traps to the server(s) whenever an alertable event occurs.
