SNMP v2
SNMP version 2 (SNMPv2) is an evolution of the SNMPv1. The Get, GetNext, and Set operations used
in SNMPv1 are exactly the same as those used in SNMPv2. However, SNMPv2 adds and enhances some
protocol operations. The SNMPv2 Trap operation, for example, serves the same function as that used in
SNMPv1, but it uses a different message format and is designed to replace the SNMPv1 Trap.
