SNMP Polling Vs SNMP Traps

Simple Network Management Protocol (SNMP) is a communications protocol that is standard in network monitoring systems. It allows for monitoring and control of SNMP-enabled devices in remote networks.

The SNMP architecture is based on the manager-agent format. The SNMP manager will collect information from your multiple SNMP agents deployed at remote sites. The agents' job is to gather remote site data and send it back to the master through the SNMP protocol.

This exchange of information can be done via polling or via traps.

In this video, Andrew explains what polling and traps are and what makes them different from one another.

I am just facinated by the fact he is writing all that backwards... or am I missing something. Thats a mind bender. Oh and the soothing spa music make sthe video so relaxing after fighting snmp trap errors!

2 years after and what a great video, I'm a spanish native speaker and the explanation is still awesome

Nice presentation, neutral voice, good preparation, and very easy going pace easily understood. Enjoyed the video.

Amazingly explained, one of the best video to understand SNMP under 5minutes.

Great explanation of Polling vs Traps! Thank You. Definitely helped a lot.

Loved the explanation and the hand movement!

[crume]

Love the explanation. Very clear. Thanks!

this is amazing! really love the vibes and calming explanation

I wish you excellent network reliability. And a christmas tree with no blinking lights!

Good advice.
I've worked with quite a bit of snmp in a wide variety of devices and the implementation in some systems is pathetic.. An afterthought in many cases just so the marketing department can include it in the feature list IMO. I worked with one fairly sophisticated security camera control system whos snmp implementation was down right frustrating. They provided no points for polling where you could find out the current status of one of the cameras, but rather it sent a trap to let you know that a camera was offline, but did not send you another trap when it came back on line and there was nothing to poll to find out.
I've also had to work with some systems that didn't provide a MIB file, so although it supported snmp, you were in the dark as to what the points where. Hours and hours of time emailing and back and forth with these companies only to have them ignore the need for fixing their problems. What was worse was the promised some would make to fix the problem in the new release and you're waiting. When you get it you find out that they didn't fix the problem at all.
My guess of course is that these companies didn't have any or many customers that actually use snmp.

Thanks for the clear message and explanation of this subject! congrats!

[zujrmte]

This is spot on! An excellent chilled explanation this really worked for me and kept me fully engaged. GoodJob!

Beautiful, I love the music too.
Got my subscription!

Thanks a lot! Your explanation was outstanding. I am currently monitoring with SNMP polling but some devices are still not recognized by the manager. In some cases I was able to install a service (win) or a client in UNIX but there's so much to investigate.

Hey thanks very much for this video, I haven't even notice your walking around.
I hope you will make more videos like this and if you could make one about subnetting would be perfect.

[haytemal-sharif]

other than him leaving and coming back in multiple times, his way of explanation was so clear and simple. this video was informative. it would have been better if the switching chapters were with fade in and out instead of walking away and walking back in.

[owaisshaikh]

thanks man nice video i wish you could show how to setup both polling and traps

[sateeshhegde]

Though indirmation is good and helpful for the beginners, from a concept point of pull and trap are different. Snmp as a standard protocol is on udp which is asynchronous. Then this protocol supports two major communications between manager and agent. Pull family of operations -Get/getnext/getbulk/walk from manager to agent and notifications/traps/informs from agent to manager.

Very well explained. Music was a bit noisy.

2:59 huh "immediacy" the quality of bringing one into direct and instant involvement with something, giving rise to a sense of urgency or excitement.
Didn't know that one
