PRTG Manual: Configuring SNMP V3 Users
The credential name is used within UVexplorer to refer to the SNMP V3 credentials
The description field contains a description of the SNMP V3 credentials
The user name used when sending requests to the device's SNMP V3 agent. The user name is used to identify who is making the request. This should be set to the value of an SNMP V3 user configured on the device.
SNMP V3 supports the idea of defining an object context that an SNMP V3 user is able to access. Context can be used to restrict an SNMP V3 user to specific information on the device. This field typically should be set the name of an SNMP V3 group configured on the device.
The authentication settings are used to authenticate an SNMP V3 user with the device. Authentication is the process of verifying that the user is who they say they are. In this case authentication is performed by providing a password. SNMP V3 authentication can be disabled; in this case no password is required. If authentication is disabled on your device, select 'None' as the protocol type to indicate that authentication is not required.
SNMP V3 authentication provides two protocols for sharing the password: SHA-1 and MD5. This setting should be set to match the configuration of the SNMP V3 agent/user of the device.
Password is the token used to authenticate the user with the device SNMP agent. This setting should be set to match the authentication password of the SNMP V3 user on the device.
Confirm password is used to ensure that the correct password is supplied. This settings should match the password exactly.
One advantage SNMP V3 has over older SNMP versions is the ability to encrypt SNMP agent communication. When encryption is used, all communication with the device is encrypted making it harder for others on the network see the information being sent and received. If SNMP V3 encryption is disabled on your device, select 'None' as the protocol type to indicate that encryption is not required.
SNMP V3 encryption provides two protocols for performing the encryption: DES and AES256. This setting should be set to match the configuration of the SNMP V3 agent/user of the device.
Password is the shared key used to initiate the encryption session. This setting should be set to match the encryption password of the SNMP V3 user on the device.
Confirm password is used to ensure that the correct password is supplied. This setting should match the password exactly.
The Show Characters check box can be used to ensure the passwords are entered correctly. When selected, the Authentication and Encryption passwords will be displayed. This option is only available when the credentials are initially created.
