Scenarios

If users need to view alarms and monitoring data of a cluster on the O&M platform, you can use the 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.
Turn on the switch on the right of SNMP Service.

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

Set interconnection parameters based on the information provided in Table 1.

**Table 1** Interconnection parameters
Parameter	Description
Version	Specifies the version of the SNMP, which can be: V2C: This is an earlier version with low security. V3: This is a higher version with higher security V3 is recommended.
Local Port	Specifies the local port. The default value is 20000. The value ranges from 1025 to 65535.
Read Community Name	This parameter is available only when Version is set to V2C. It is used to set the read-only community name.
Write Community Name	This parameter is available only when Version is set to V2C. It is used to set the write-only community name.
Security Username	This parameter is available only when Version is set to V3. It is used to set the protocol security username.
Authentication Protocol	This parameter is available only when Version is set to V3. It is used to set the authentication protocol. SHA is recommended.
Authentication Password	This parameter is available only when Version is set to V3. It is used to set the authentication key.
Confirm Password	This parameter is available only when Version is set to V3. It is used to confirm the authentication key.
Encryption Protocol	This parameter is available only when Version is set to V3. It is used to set the encryption protocol. AES256 is recommended.
Encryption Password	This parameter is available only when Version is set to V3. It is used to set the encryption key.
Confirm Password	This parameter is available only when Version is set to V3. It is used to confirm the encryption key.

NOTE:

The value of Security Username cannot contain repeated character strings with the unit length is 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, you need to periodically change the authentication and encryption passwords when using SNMP.
If SNMPv3 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. On 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 IP address mode of the destination IP address. This parameter can be set to IPV4 or IPV6.
- Target IP Address: specifies the IP address of the target trap. Destination IP address, which must be able to 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.
