About SNMPv3
SNMPv3 settings are under Administration > System Settings: SNMP v3. SNMP v3 provides additional authentication and access control for message security. For example, you can verify the identity of the SNMP entity (manager or agent) sending the message. SCC supports SNMPv3 message encryption for increased security.
Using SNMPv3 is more secure than using SNMPv1 or v2; however, it requires more configuration steps to provide the additional security features. These are the basic steps
1. Create the SNMP-server users. Users can be authenticated using either a password or a key.
2. Configure SNMP-server views to define which part of the SNMP MIB tree is visible.
3. Configure SNMP-server groups, which map users to views, allowing you to control who can view what SNMP information.
4. Configure the SNMP-server access policies that contain a set of rules defining access rights. Based on these rules, the entity decides how to process a given request.
