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 SNMP Operational Model, Components and Terminology.
(Page 1 of 3)

So, it seems the “Simple” Network Management Protocol (SNMP) isn't quite so simple after all. There are many versions and standards and uses of SNMP, and so a lot we need to learn. I think a good place to start in understanding what SNMP does is to look at its model of operation, and examine the components that comprise a TCP/IP network management system and the terminology used to describe them.

SNMP Device Types

As we saw in the preceding high-level overview topic, the overall idea behind SNMP is to allow the information needed for network management to be exchanged using TCP/IP. More specifically, the protocol allows a network administrator to make use of a special network device that interacts with other network devices to collect information from them, and modify how they operate. In the simplest sense, then, two different basic types of hardware devices are defined:

  • Managed Nodes: Regular nodes on a network that have been equipped with software to allow them to be managed using SNMP. These are, generally speaking, conventional TCP/IP devices; they are also sometimes called managed devices.

  • Network Management Station (NMS): A designated network device that runs special software to allow it to manage the regular managed nodes mentioned just above. One or more NMSes must be present on the network, as these devices are the ones that really “run” SNMP.
