Managing Trap Settings

Trap is a Simple Network Management Protocol (SNMP) message type that indicates the occurrence of an event. This type of message is sent to a recipient through User Datagram Protocol (UDP), which is not fully reliable. If alarm information is reported in SNMP mode, you need to configure a trap server IP address. After a trap server IP address is configured, alarm information about a storage device will be sent to the specified application server or maintenance terminal.

Procedure

  1. Choose Settings > Alarm Settings > Alarm Notification > Trap Settings.
  2. View Trap notification parameters. Table 1 describes related parameters.

    Table 1 Trap notification parameters

    Parameter

    Description

    Server Address

    Address of a trap server (which can be a network management system or a storage system) for receiving alarm messages.

    Port

    Port number of the server address. The value ranges from 1 to 65535.

    Version

    SNMP version used by a server. Possible values are SNMPv1, SNMPv2c, and SNMPv3.

    NOTE:
    • SNMPv1 and SNMPv2c use community strings for authentication.
    • SNMPv3 supports the authentication and encryption of data. USM users need to be configured to implement data authentication and encryption.
    • For security purposes, SNMPv3 is recommended.

    Type

    Type of alarms sent by the storage system to a trap server, including:

    • Parsed: The storage system sends parsed alarms to a trap server. IDs of all alarms correspond to the same object identifier (OID).
    • Parsed time string: The storage system sends parsed alarms to a trap server. IDs of all alarms correspond to the same OID. The data type of the alarm occurrence time field is OCTET STRING.
    • Parsed time string precise: The storage device sends parsed alarms to a trap server. The ID of each alarm corresponds to an independent OID, and different OIDs are used for alarm generation and clearance.
    • Original time string: The storage system sends unparsed original alarms to a trap server. Both the alarm occurrence time (character string) and alarm clearance time (character string) are of the OCTET STRING data type.
    • All: The storage device sends all types of alarms to a trap server, including Parsed, Parsed time string, and Original time string.

    USM User

    User who reports alarms using SNMP.

  3. Set server addresses.

    • Adding a server address
      1. Click Add.

        The Add Recipient Server page is displayed on the right.

      2. Configure parameters for the recipient server to be added. For details about the parameters, see Table 1.

        When you click Manage USM User on the right of the Add Recipient Server page, the SNMP Protocol page is displayed.

      3. Click OK.
    • Deleting a server address
      1. Select the desired server address and click Remove.
      2. Confirm your operation as prompted.
    • Modifying a server address
      1. Select the desired server address and click Modify.

        The Modify Recipient Server page is displayed on the right.

      2. Modify parameters of the recipient server. For details about the parameters, see Table 1.
      3. Click OK.
    • Testing a server address

      Select the desired server address and click Test to test connectivity between the storage system and the server.
