Software User Manual 12/10/09 D-Link Unified Access System • Privacy: Protects against disclosure of message content. Cipher-Bock-Chaining (CBC) is used for encryption. Either authentication is enabled on an SNMP message, or both authentication and privacy are enabled on an SNMP message. However privacy cannot be enabled without authentication. • Timeliness: Protects against message delay or message redundancy. The SNMP agent compares incoming message to the message time information. • Key Management: Defines key generation, key updates, and key use. The device supports SNMP notification filters based on Object IDs (OID). OIDs are used by the system to manage device features. SNMP v3 supports the following features: • Security • Feature Access Control • Traps Authentication or Privacy Keys are modified in the SNMPv3 User Security Model (USM).
