SNMP Versions

The agent supports multiple versions of the SNMP protocol.

• SNMP Version 1 (SNMPv1) is the original Internet-standard network management framework.

  SNMPv1 provides access control for communities and uses a community string match for authentication.

• SNMPv2c uses a community string match for authentication.

• SNMP Version 3 (SNMPv3) provides access control for users. In SNMPv3, User-based Security Model (USM) defines the user authentication and encryption features. The View Access Control MIB (VACM) defines the user access control features. The SNMP-COMMUNITY-MIB is used to associate SNMPv1/SNMPv2c community strings with SNMPv3 VACM access control.

  SNMPv3 uses a username match for authentication.
