Please Whitelist This Site?
I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. 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.
Thanks for your understanding!

TCP/IP Internet Standard Management Framework and SNMP Standards
We've now seen that there are three different versions of the Internet Standard Management Framework. Some of these versions have different variants. Each version or variant of the Framework includes multiple modular components. Each component has one or more documents that define it. Some of these have multiple revisions. Add to that dozens of individual Management Information Bases (MIBs) defined for SNMP and other support documents and what do you have? A boatload of TCP/IP standards, that's what. There are probably more RFCs defining parts of SNMP than any other single TCP/IP protocol or technology.
It is specifically because there are so many versions and components and documents associated with SNMP that I feel it is important to keep all the standards straight. To that end I have created a number of tables, which show the major SNMP standards for each of the versions and variants of the SNMP Framework. Each individual RFC defines one component of one version of the Framework.
The usual way that RFCs work is that when new versions of a standard are released that are direct replacements for older ones, the older ones are “obsoleted” by the new ones. With SNMP, due to the many versions and the controversy over the variants, this is a bit unclear. For example, the standards defining SNMPv2p are not considered by the IETF to obsolete the standards for SNMPv1, but the IETF says the standards for SNMPv2c and SNMPv2u do obsolete those of SNMPv2p.
To keep all of this distinct I have made the decision to show the standards for each version or variant separately. I only put the RFC numbers for obsolete RFCs where those RFCs are for the same SNMP version or variant. For example, RFC 3410 obsoletes 2570 because they both deal with SNMPv3 and 3410 is a direct replacement for 2570. Also, there are a few cases where the name of a standard changed slightly between RFC numbers; I have shown the current name.
Each of the six tables below shows the current and obsoleted standards for one of the SNMP versions or variants: SNMPv1 (Table 199); SNMPSec (Table 200); SNMPv2p (Table 201); SNMPv2c (Table 202); SNMPv2u (Table 203) and SNMPv3 (Table 204). (SNMPv2* was not standardized using the regular RFC process.)

Management Information Base (MIB) for the Simple Network Management Protocol (SNMP) |
In addition to all of these tables, as I mentioned before, there are dozens of supplemental RFCs that describe MIB modules and also clarify various fine points of operation related to SNMP. Listing all of these would… make me go insane. Sorry, those tables were bad enough. J You can find all the MIBs in an online list of RFCs by searching for “MIB” or “SNMP”.
