Technical Focus:Technical Focus: SNMP VersionsSNMP Versions
SNMP has gone through three different versions:
SNMPv1 was based on the network management principles defined by the OSI model.
SNMPv2 was designed to be totally dependent onthe Internet model.
SNMPv3 is the latest version and adds security management to SNMPv2.

Technical Focus:Technical Focus: SMISMI
To perform its job, SNMP uses other protocols. One of these protocols is called Structure of Management Information (SMI).
SMI is used to do the following:
1. Universally and uniquely name objects to be managed.
2. Define the type of data that can be stored in objects.
3. Show how to encode data for transmission over the network.

Technical Focus:Technical Focus: MIBMIB
SMI uses another important protocol called ManagementInformation Base (MIB). SMI defines how a universalcollection of objects should be named and managed. MIB, on the other hand, defines which of these objects should be included in a particular agent.
