SNMPv1, SNMPv2, SNMPv3 Comparison

Version 1

  • First appeared in 1988.
  • The most commonly deployed version of SNMP.
  • Security is extremely poor. Passwords are transmitted as plaintext.

Version 2

  • Adds new request types to receive large amounts of data with a single request.
  • Introduced a new security system to address the major issue with SNMP1. This security system was overly complex so SNMPv2 was rarely implemented.

Version 3

Makes security more manageable and remote configuration enhancements.

Recognized by the Internet engineering Task Force as a fully mature internet standard.
