Configuring SNMP Northbound Parameters

Scenario

If users need to view alarms 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

1. Log in to FusionInsight Manager.
2. Choose System > Interconnection > SNMP.
3. Toggle on SNMP Service.

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

4. Set interconnection parameters according to Table 1.

   Table 1 Interconnection parameters

   Parameter	Description
   Version	Specifies the version of SNMP, which can be: V2C: This is an earlier version with low security. V3: This is a later version with higher security than SNMP V2C. SNMP V3 is recommended.
   Local Port	Specifies the local port. The default value is 20000. The value ranges from 1025 to 65535.
   Read Community Name	Specifies the read-only community name. This parameter is available only when Version is set to V2C.
   Write Community Name	Specifies the write community name. This parameter is available only when Version is set to V2C.
   Security Username	Specifies the SNMP security username. This parameter is available only when Version is set to V3.
   Authentication Protocol	Specifies the authentication protocol. This parameter is available only when Version is set to V3. SHA is recommended.
   Authentication Password	Specifies the authentication password. This parameter is available only when Version is set to V3.
   Confirm Password	Used to confirm the authentication password. This parameter is available only when Version is set to V3.
   Encryption Protocol	Specifies the encryption protocol. This parameter is available only when Version is set to V3. AES256 is recommended.
   Encryption Password	Specifies the encryption password. This parameter is available only when Version is set to V3.
   Confirm Password	Used to confirm the encryption password. This parameter is available only when Version is set to V3.

   

   • 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.

5. 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.
