SNMPv3

Last Updated : Nov 06, 2012 |

SNMPv3 enables the following features over SNMPv1 or v2c:

  • User authentication with a username and password

  • Communication encryption between the Network Management Station (NMS) and the SNMP agent at the application level

  • Access control definition for specific MIB items available on the SNMP agent

  • Notification of specified network events directed toward specified users

  • Definition of roles using access control, each with unique access permissions and authentication and encryption requirements

The basic components in SNMPv3 access control are users, groups, and views. In addition, SNMPv3 uses an SNMP engine ID to identify SNMP identity. An SNMP engine ID is assigned to each MAC address of each device in the network. Each SNMP engine ID should be unique in the network.
