17 SNMPv3
SNMP (Simple Network Management Protocol) is the most widely-used network management protocol on
TCP/IP-based networks. SNMPv3 is designed mainly to overcome the security shortcomings of
SNMPv1/v2. USM (User based Security Mode ) and VACM (View based Access Control Model) are the
main features added as part of the SNMPv3 specification. USM provides for both encryption and
authentication of the SNMP PDUs, while VACM specifies a mechanism for defining access policies for
different users with different MIB trees. Also, SNMPv3 specifies a generic management framework, which
is expandable for adding new Management Engines, Security Modes, Access Control Models, etc. With
SNMPv3, the SNMP communication is completely safe and secure.
SNMPv3 is a multi-lingual Agent supporting all three versions of SNMP (SNMPv1, SNMPv2c and
SNMPv3) while conforming to the latest specifications. It is available as a portable source code product,
which can be easily integrated to any platform (any OS and any Processor). MIB integration is made
simple with the aid of a tool called Middle Level Code Generator (MIDGEN), which is available along with
SMIS SNMP . MIDGEN generates the interface stubs required for every object in the MIB for the SET,
GET and GETNEXT operations.
These stubs can be implemented by the respective modules supporting the MIB. SMIS SNMP is provided
as source code available for licensing to OEMs and VARs who wish to incorporate the multilingual SNMP
functionality into their products.
The list of CLI commands for the configuration of SNMPv3 is as follows:
