Configuring SNMP Northbound Parameters
======================================

Scenario
--------

If users need to view alarms and monitoring data of a cluster on the O&M platform, you can use Simple Network Management Protocol (SNMP) on FusionInsight Manager to report related data to the network management system (NMS).

Procedure
---------

#. Log in to FusionInsight Manager.

#. Choose **System** > **Interconnection** > **SNMP**.

#. Toggle on **SNMP Service**.

   The SNMP service is disabled by default. |image1| indicates that the service is enabled.

#. Set interconnection parameters according to :ref:`Table 1 <admin_guide_000154__en-us_topic_0046736864_tab01>`.

   .. note::

      -  The value of **Security Username** cannot contain repeated strings with the unit length as a common factor of 64 (such as 1, 2, 4, and 8), for example, **abab** and **abcdabcd**.
      -  The **Authentication Password** and **Encryption Password** must contain 8 to 16 characters, including at least three types of the following characters: uppercase letters, lowercase letters, digits, and special characters. The two passwords must be different. The two passwords cannot be the same as the security username or the reverse of the security username.
      -  For security purposes, periodically change the authentication password and encryption password when the SNMP protocol is used.
      -  If SNMP v3 is used, a security user will be locked after five consecutive authentication failures within 5 minutes. The user will be automatically unlocked 5 minutes later.

#. Click **Create Trap Target** in the **Trap Target** area. In the displayed dialog box, set the following parameters:

   -  **Target Symbol**: specifies the trap target ID, which is the ID of the NMS or host that receives traps. The value consists of 1 to 255 characters, including letters or digits.
   -  **Target IP Address Mode**: specifies the mode of the target IP address. The value can be **IPv4** or **IPv6**.
   -  **Target IP Address**: specifies the target IP address, which can communicate with the management plane IP address of the management node.
   -  **Target Port**: specifies the port receiving traps. The port number must be consistent with the peer end and ranges from 0 to 65535.
   -  **Trap Community Name**: This parameter is available only when **Version** is set to **V2C** and is used to report the community name.

   Click **OK**.

   The **Create Trap Target** dialog box is closed.

#. Click **OK**.
