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! Sincerely, Charles Kozierok Author and Publisher, The TCP/IP Guide

SNMP Framework Architecture

The creators of SNMP specifically designed the Framework to be modular because when SNMP was originally created, it was seen as only a temporary solution until a transition could be made to another network management protocol from the OSI protocol suite. The modular architecture separated definitional, data and functional (protocol) elements, to allow the SNMP protocol itself to be replaced without changing how network management information was defined and described.

This transition to the OSI protocol never occurred, but the architecture has still proven valuable in defining the entire scope of SNMP and in making its implementation much simpler. Each of the major components above, the SMI, MIBs and SNMP itself, are described in different standards. The modularity of the SNMP Framework has also allowed changes to be made to these components relatively independently of each other, making the transition between SNMP versions easier than it would have been if one huge document defined everything.
