I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :) If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads. If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Further Development of SNMP and the Problem of SNMP Variations

The description above provides the history of how the first version of SNMP was developed, leading to the publishing of the first Internet Standard Management Framework in 1988; this is now called SNMP version 1 (SNMPv1). This initial version of SNMP achieved widespread acceptance, and it is still probably the most common version of SNMP.

Much of the history of SNMP since that time has been a rather confusing “standards nightmare”. SNMPv1 had a number of weaknesses, particularly in the area of security. For this reason, shortly after SNMPv1 was done, work began on a new version of SNMP. Unfortunately, this effort became a quagmire, with many competing variations of SNMPv2 being created. After many years of confusion, none of the SNMPv2 variants achieved significant success.

Recently, a third version of the SNMP Framework and Protocol has been published, which adds new features and “reunites” SNMP back under a single universal protocol again. The topics on SNMP versions and SNMP standards later in this section further explore the history of SNMP since 1988; they can be considered a continuation of this topic, as they help clarify the very confusing story behind SNMP versions over the last decade and a half.

This overview may have put more questions in your mind about the Internet Standard Management Framework and SNMP than it answered. This is part of why I said this stuff isn't really that simple. J The next two topics in this section provide more information about the Framework and its components, and what those components do, so you can understand better what the Framework is all about.
