- Do you want to know more details about the SNMP protocol? Start here www.dpstele.com/snmp/index.php
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!
I think he used Image mirroring to make it readable for us viewers. But if he did write backwards, that be awesome
2 years after and what a great video, I'm a spanish native speaker and the explanation is still awesome
Great explanation of Polling vs Traps! Thank You. Definitely helped a lot.
this is amazing! really love the vibes and calming explanation
Loved the explanation and the hand movement!
Love the explanation. Very clear. Thanks!
Thanks for the clear message and explanation of this subject! congrats!
Glad you enjoyed it!
Amazingly explained, one of the best video to understand SNMP under 5minutes.
This is spot on! An excellent chilled explanation this really worked for me and kept me fully engaged. GoodJob!
Nice presentation, neutral voice, good preparation, and very easy going pace easily understood. Enjoyed the video.
Beautiful, I love the music too.
Got my subscription!
Good video to learn the concept!
Very clear. Thanks!
Good vid! Thank you.
Thanks for the background music!
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 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.
Thank you!
I wish you excellent network reliability. And a christmas tree with no blinking lights!

Thank you so much
Good video!
Good info thanks!
Glad it was helpful!
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.
Sure, I think subnets, subnet masks, and VLAN would be good topics. Subnets really confused me when I first started learning about IP. I'll add those to my list.
Thanks!
i love the background music
thanks man nice video i wish you could show how to setup both polling and traps
Thanks for the idea. I'll likely do a future video showing the setup process with our T/Mon as an example.
Thanks
thanks
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.
You are correct. Check out our newer videos that take this advice to heart.
What a useless comment
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.
Yes, this is absolutely a video for beginners. TCP vs. UDP is a deeper concept for another video. My only goal here was to cover the two broad types of messages. I'll be getting into GETs/SETs more specifically in future videos. Thanks for watching!
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
Ad hoc vocabulary lessons are all part of the service here at DPS. 😆
Very well explained. Music was a bit noisy.
Why this guy going out and coming into frame 1000 times.... It's not appealing or looking good... Stay calm and stay still
I asked my self the same question :) what is the benefit of going out the frame and in again all the time... beside that great instructional video.
@@itzikvil1 exactly he explained it well but the walking out of frame is distracting 😆
On the other hand, if they would just make a studio, and put up some laser lights and LED strips, they could make the whole thing look like a Star Wars strategy center!
@witch blade But what about the laser lights and LED Xmas show??? :'(
Thanks for the feedback. The people have spoken, and you are among them. We corrected this in later videos.
i loved this video?it would hv been nice if m rmon was mentioned
Sure, I think I could make some videos about common SNMP managers that are available. It's nice that SNMP has so much interoperability, but that does mean that there are many different managers to learn.
❤️
Explanation is Good.But it could me more intresting if the background music is absent.
good
Thanks!
Agent:"I want to speak to the manager"
hilarious
What’s an agent? A computer? What’s a manager? I understand the concept of this communication just trying to see the bigger picture
i fkin love you boy
So what's an SNMP trap??
Keep snmp for legacy else ask vendor for telemetry support. Real time data.
Or use Yang and Netconf
Where do you keep going?
Good catch! Am I snacking? Checking my notes? Nervously diving out of the spotlight?
The truth: This was our first lightboard video. I walked off camera to smooth out the cuts so that I wouldn't vanish or teleport when we cut between shots (we had to stop to erase the board between segments). As it turns out, the text overlays between sections cover the cuts anyway. Please be sure to check out our newer lightboard videos, which have better lighting contrast and are generally only as long as it takes to cover one board.
Background music link or name please?
If anyone's wondering the song name is 'First Steps' by 'Be Still The Earth'

- Administrador (manager): Rercoleta la información de los agentes.
- Agente: Pieza de software en el dispositivo gestionado.
- Mensajes SNMP: TRAP y pollings (getRequest, nextREquest, etx.).
- TRAP: Mensaje asincrónico e inmediato que lanza el agente. El dispositivo puede estar desconectado y no lo sabremos si no se le puede enviar pollings.
- Polling: Mensaje sincrónico que lanza el agente y que espera un respuesta.
- Ciclo de polling: Un administrador lanza un mensaje polling y recibe un respuesta del agente, y esto se repite cada cierto tiempo (p. e. 1 min). Permite saber si el dispositivo gestionado está disponible o desconectado.
The music is too loud.
this guy is not left handed, lets see who was oberving and can tell me why :-)
The poster in the background is proof, and the reason why is so he can write it easily and then flip it to display it for the user.
Well played! In another video, I actually made backwards signs to throw you off the scent. Unless I can find shirts with pockets on the right side, the illusion is never going to be perfect.
Stop walking away!
I don't know why this guy keeps walking out of the screen...
The walking in and out is too painful to finish this informative vid sorry :(
Point taken! I've recorded about 10 more lightboard videos since this one, and I stay in one place!
U shout stay at one place while making informative videos. .
Gng off and on the screen is making loose the intrest of getting information.
I agree. This was our first use of this technology. Be sure to check out our new-and-improved videos.

Die Musik nervt.
Very nice and concise explanation!
