The SNMP Communication Driver supports authentication only for SNMP v3. If the station is configured to communicate using SNMP versions 1 or 2, the authentication settings are ignored and not used.

Authenticate the Connection

The Authentication section allows you to configure the security settings for every station.

SNMPAuthentication_PrivacyType_2026

  1. Security Level: Set the security level used for SNMP v3 messages. From the Security Level list, select one of the options:

    1. No security: Select this security level if no authentication is required.

    2. Authentication only: This enables the Authentication Type, Privacy Type, Username and Password fields.

    3. Authentication and Privacy: This enables the Authentication Type, Privacy Type, Username, Password, and Private key fields.

  2. Authentication Type: Select the authentication protocol used for authenticated SNMP v3 messages:

    • MD5

    • SHA

    • SHA-256

    • SHA-512 (default)

  3. Privacy Type: Select the encryption type:

    • AES (default): We recommend you to select this encryption type. It is more secure because it supports larger key sizes, and its use of larger block sizes makes it highly efficient.

    • DES: This encryption type is only supported for compatibility with older standards. However, it is less secure and efficient than AES encryption.

  4. Username: Set the security name used for authenticated SNMP v3 messages

  5. Password: Set the authentication pass phrase used for authenticated SNMP v3 messages.

    Note: The Username and Password must be provided when using any security level higher than No security.

  6. Private key: Set the privacy pass phrase used for encrypted SNMP v3 messages. The Privacy key is enabled and is mandatory only when using security level of Authentication and Privacy.
