SNMP Version 3 provides security features such as authentication (verifying that the request comes from a genuine source), privacy (encryption of data), authorization (verifying that the user allows the requested operation), and access control (verifying that the user has access to the requested objects). To prevent SNMP packets from being exposed on the network, you can configure encryption with SNMPv3.
Instead of using community strings like SNMPv1 and v2, SNMPv3 uses SNMP users.
In the serviceability GUI, you configure SNMPv3 support in the V3 Configuration window.
