A list of SNMP Features would be useful

To help the newbie understand the 'why' of SNMP, it might be useful to start this article with a list of SNMP's features, such as

provides a way to ask a device on a network to describe itself.
information is organized by keyword and a corresponding value, for example you can ask a device for its 'sysLocation' and receive a response like 'Room 202A'.
There is a single family tree (hierarchy) of keywords for all of SNMP, which makes it easy to attach new branches to this tree as new needs arise.

I'd say more explanation than that is due, but your comment certainly explains more about it than the entire article. Usually the first paragraph of an article gives you a good general overview of the topic, but the first paragraph amounts to little more than what the first sentence alone says: Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks." The quotation marks around the definition there are a nice touch: it's as if it's some sort of acknowledgement that even the author couldn't pin down an actual explanation of what the protocol does and didn't want to present such a vague definition as their own work.

So I continued to read the article, but never found an answer about what exactly the protocol does. It just keeps referring to what SNMP does as "management" without ever explaining what is meant by "management." So I'm left wondering, what does "managing devices" mean? I sometimes manage my network devices by unplugging cables, moving them to a different room, and plugging in new cables. Does SNMP do this for me? Sometimes I manage my network devices by assigning them IP addresses, does SNMP do that? Sometimes I manage devices by upgrading their firmware. Does SNMP do that? Sometimes I manage my router by adding new port forwarding rules. Does SNMP do that? "Manage devices" is a uselessly vague definition of what the protocol does, whatever that might be.

My only guess is that the protocol doesn't actually do anything, but rather, it's somewhat like TCP and UDP wherein you might use it to transfer information between devices, but exactly what data any device chooses to send, receive, or act upon, is entirely undefined, and depends on the software running on those devices. The only difference being that maybe it defines a standard format for that data, like "variable name goes here" and "an ID code for the data type goes here" and "the data goes here," but otherwise the protocol doesn't attempt to define what data should be sent or what actions should be taken in response to it. ...but, I really have no idea. The entire rest of the internet seems to be equally clueless about what this protocol actually does and what it might be used for and so I've been unable to figure anything out.

Varbind missing

The term "Varbind" is redirected to this page. This page, however, does not contain the word "Varbind." —Preceding unsigned comment added by 206.169.32.3 (talk) 19:24, 27 August 2009 (UTC)[reply]

Introduction to SNMP, with an overview of RFCs

RFC 3410 provides a valuable introduction to the SNMP framework, and an overview of the many RFCs relating to it.

Inclusion of reference to xkcd as explanation for entropy

I question referecence 12, i.e. the reference to an xkcd comic, for demonstrating password entropy and perceived usability of long passwords. If it is deemed desirable that such an explanation be included, a reference to a research paper should be included. However, I do not think that explaining useful passwords is an important contribution to an article about SNMP, either. 131.159.20.131 (talk) 14:33, 17 August 2011 (UTC)[reply]
