SNMP comes in three different versions which all have their benefits and drawbacks.nn SNMP v1 is the most basic SNMP version. While it is quite universally applicable as most SNMP-enabled devices support it, it also has major security limitations. In addition, SNMPv1 only supports 32-bit counters.n SNMP v2 is the most used SNMP version. In contrast to SNMP v1, it also supports 64-bit counters; however, it has the same security limitations.n SNMP v3 provides authentication and optional data encryption. However, this also results in more overhead and needs more configuration work.
