SNMPv2c offers protocol enhancements such as the GETBULK operation. SNMPv3 provides a network management framework that allows the use of user-based security in addition to, or instead of, the community-based security supported in SNMPv1 and SNMPv2c. The view-based access control model supported in SNMPv3 allows granular access control for MIB objects with either the user-based or community-based security models. SNMPv3 also enables dynamic changes to the SNMP agent configuration.
