SNMP VERSION
The different versions of SNMP are SNMPv1, SNMPv2c and SNMPv3.
• SNMPv1 is the first version of the protocol, which is defined in RFC 1157.
• SNMPv2c is the revised protocol, which includes enhancements of SNMPv1 in
the areas of data type efficiency and performance, confirmation of event
notification, error handling, set operation, transport independence, and MIB
structure elements. But SNMPv2c uses the existing SNMPv1 administration
structure. It is defined in many RFCs such as RFC 1902 to 1907.
• SNMPv3 defines the secure version of the SNMP. It also facilitates remote
configuration of the SNMP entities and is defined in RFC 2571 to RFC 2575.
SNMPV3 PROTOCOL OVERVIEW
SNMP Version 3 (SNMPv3) is an interoperable standard based protocol for
network management. It provides secure access to devices by a combination of
authenticating and encrypting packets over the network. The security features
provided in SNMPv3 are:
• Message integrity - ensuring that a packet has not been tampered with in-transit.
• Authentication - determining the message is from a valid source.
• Encryption - scrambling the contents of a packet prevents it from being seen by an
unauthorized source.
SNMPv3 provides both security models and security levels. A security model is an
authentication strategy that is set up for a user and the group in which the user
resides. A security level is the permitted level of security within a security model. A
combination of a security model and a security level determines which security
mechanism is employed when handling an SNMP packet. Three security models
are available: SNMPv1, SNMPv2c, and SNMPv3.
Three security levels are available: Auth, Noauth, and Priv.
