Chapter 2. SNMPv1 and SNMPv2

In this chapter, we start to look at SNMP in detail, specifically covering features found in SNMPv1 and SNMPv2 (we'll allude to SNMPv3 occasionally but we describe its features in detail in Chapter 3). By the time you finish this chapter, you should understand how SNMP sends and receives information, what SNMP communities are, and how to read MIB files. We'll also look in more detail at the three MIBs that were introduced in Chapter 1, namely MIB-II, Host Resources, and RMON.
