OMG! I am so glad that found your channel!! Great video! watched the whole thing and took notes! Gonna check out some more of what you have on QoS as I have been teaching myself while configuring EMC Powerswitch 5232F-ON for our HCI RoCE 100GbE deployment. Great stuff, thanks for doing this!
I really enjoy your deep dives, just bumped into your classes few days ago and I'm taken. QOS is one of my worst nightmares, I found it very hard to understand till now, sooo many thanks for this!
I read 3-4 different books on Encor multicast, and watched a couple of videos. That last read on the topic finally allowed me to make sense of it all thank God. The OCG did a pretty poor job of explaining the multicast concepts for me, and the errors in that book are ridiculous.
Best video, everything under one roof. 👌🏻 SUBSCRIBED.. ❤ Can you suggest some books to dive deep into the topics of WLan networking and computer networking, your videos + books together will help a lot...
Great course. I still have one doubt. If I have understood correctly, ingress and egress qos policies will be applied on access ports where endpoints will connect. what about uplink port of the switch? will any QoS policy apply on that port?
The ECN bits don't make sense to me. Why would the ECN capable bit ever be set to 0 (off) if it's ECN capable? If bits 7 and 8 are set to 01 or 10 that means the router is ECN capable, but why would it be 01 in the first place?
Thanks! I’m glad you enjoy our training. To answer your question, I would say Policing is best for TCP traffic, because it can drop traffic. In that case, TCP would retransmit the dropped traffic, while UDP traffic would be dropped without retransmission.
Thanks Kevin, great as always. One quick question - my company uses ''match ip dscp ef'' statement under class-map configuration, and I have been assigned a task to mark Zoom traffic, as we are going to use zoom now. Zoom DSCP values are 56 for voice and 46/40 for video. Can't get head around, if I want mark this traffic, firstly, I assume I have to classify it in the class map? Or shall I simply move under policy-class/map configuration and simply mark it with a set dscp ''value'' command? Also to confirm, can I actually match traffic based on dscp vallue under the first class-map configuration? Even if I wont get a response, I really enjoy your videos. Thanks Kev
At 1:14:40 Dual-Bucket Dual-Rate: It is not clear what does it mean, when you say, we are not able to send traffic from the CIR bucket? Why would be not able to send the traffic once the bucket is full, when we can send it from the PIR bucket? Many thanks in advance for everything, I love your classes and I still come back to them to refresh my understanding once in a while, Ironically I always find a word or two that you mentioned and I messed! A FAN FOR MANY YEARS!!
Hi, Mr. Wallace I have a favor to ask could u make a lesson to help us how to use Cisco documentation it would be super nice I've just passed my CCNA and now I m on my way to CCNP THX anyway
It struck me that what DiffServ is doing is splitting the converged data and voice network back into logically separated networks on a unified physical layer.
There is a mistake at 38:00 Kevin says that the min threshold for high drop probability but it should be min threshold for low drop probability.....same mistake repeated at 50:01 where he says not exceeded the min drop threshold for medium and high, it should be not exceeded the min drop threshold for medium and low...

Kevin ! Kevin ! you are just amazing. QoS has always been a nightmare for me; boom you have demystified it
I really enjoy your deep dives, just bumped into your classes few days ago and I'm taken. QOS is one of my worst nightmares, I found it very hard to understand till now, sooo many thanks for this!
Awsome lesson on QoS. Thanks, Kevin!
Very useful. Many Thanks!
Informative
I am planning to make it a graduation theme wish me best
Awesome! All the best.
Qos
This is probably the wrong place to put this but who agrees the next deep dive topic should be on multicast?
It would be a quick deep dive.
Oh yes!! Chap 13 Encor OCG 😂 Nightmare 👻
I read 3-4 different books on Encor multicast, and watched a couple of videos. That last read on the topic finally allowed me to make sense of it all thank God.

@@mistereman345 Would you mind sharing which "last read on the topic finally allowed me to make sense of it"?
Please, do this ^ IGMP 2 and queriers deep dive

thank you Mr Wallace i used to skip that part loool i took time for that, watching it twice ... thank's again (from France)

Yes I have the same question
How does it work with DMVP environment?
Cheers Mate. That was a Awesome Intro to QOS. Cheers
Best ever explanation of qos❤
I was waiting for this! Thanks
Love your videos.
I thought policing was best for UDP traffic and shaping for TCP traffic. Is my statement still the case?
Thanks! I’m glad you enjoy our training. To answer your question, I would say Policing is best for TCP traffic, because it can drop traffic. In that case, TCP would retransmit the dropped traffic, while UDP traffic would be dropped without retransmission.
Great course. Well worth the time. Thanks Kev!
Good Video, Thanks Kevin. I would also appreciate more practices.
Thanks Kevin, great as always.

Great explanation. I have good experience on the QoS offload to high speed SmartNIC/DPU
Awesome thank you so much this clears up a lot! Getting ready for encor v1.1
Brain almost exploded trying to make sense and purpose of the AF class vs the drop probability lol
Every topic i find in ENCOR i struggle with theres a deep dive on. Must be intentional
Off topic but has anyone told you you kind of sound like Goofy? lol anyways thanks for the great content! :)

This man is simply amazing!! honestly the best and most interesting lectures i'v ever listened to!
Can someone please suggest a book for the Wlan networking, where we can dive deep.. Thanks in advance 😊

Hello Mr. Wallace after some English courses I can tell you now that I'm enjoying listening to you even tonnes of hours
Thank you Kevin! 👋from Colombia
Thank you so much, that was a great course
This is so great! Awesome job!
You are the best ❤

Great one!

heay Mr wallace thx for all u re support but an advice for non ensglish speaker can u just speak slowly that s it and God bless u
