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 > System Settings > Alarm Notification > Trap Settings.
  2. View information about server addresses.

    1. View trap notification parameters. Table 1 describes related parameters.

      Parameter

      Description

      Server Address

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

      Port

      Indicates the port used by a trap server to receive alarm messages. The value ranges from 1 to 65535.

      Version

      Indicates the SNMP version used by a trap 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

      Indicates the type of alarms sent by the storage system to a trap server.

      • 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.
      • 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 system sends both parsed and original alarms to a trap server.

      USM User

      Indicates the user account that 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. Table 1 describes related parameters.

        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. Table 1 describes related parameters.
      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.
