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!

SNMP Protocol Operations

The Simple Network Management Protocol (SNMP) is the protocol responsible for allowing network management stations on a TCP/IP internetwork to perform management tasks with managed devices. The core of the protocol consists of a set of protocol operations that allow management information to be exchanged between SNMP agents and managers. Having previously examined the generalities of SNMP and what MIB objects are, we can now get down to the “nitty gritty” of how management information is actually communicated using SNMP. Yes, finally you get to actually see how SNMP “works”.

In this section I provide a detailed description of the operations performed by the SNMP Protocol. I begin with a general description of how SNMP operates and the two basic methods devices use to communicate; I also describe SNMP's message classes. I then provide topics that describe in detail each of the basic operations performed in SNMP and the messages used for those purposes: basic request/response, table traversal, object modification, and notification. I conclude with a discussion of SNMP security issues and a summary of the security methods in each of the SNMP versions.

Note that the number and types of protocol operations in SNMP changed between SNMPv1 and SNMPv2. The operations defined in SNMPv2 have been carried forward into the newest version, SNMPv3. Most of the discussion focuses on SNMPv3 as the newest implementation, while mentioning what differences there are between it and the original and still widely-used SNMPv1.
