for anyone actually taking the ccna. the majority of the questions focus on knowing: subnetting by heart, everything about switchports, wireless, ipv6, and misc troubleshooting a variety of things. the questions also change to focus on what you are weakest at. so if you do bad on subnetting, like me, you will receive many more subnetting questions. the test is not hard itself but cisco exams are mostly trick questions which feels scummy for a knowledge test. feels like they made the wording as difficult as possible to boost their prestige . you will fail questions over grammar and word choice.

just a note on the Boson Quiz question but 'channel-group 1 mode on' is a valid command as long as both switches are using the 'on' mode. the reason answer B is correct is because you cant mix the LACP and PAGP protocols on an Etherchannel, they must be the same on both switches.

Hi Jeremy, I read the answer explanation of the Boson Ex-Sim bonus question, it stated that if I configured two static Etherchannel ports on both switches with the CLI command "mode on" , the link will be established but without an aggregation protocol. Now my question is: is data going to be transferred in both directions if no aggregation protocol is configured?

@JeremysITLab 4 года назад

AbdElRahman ElSherbiny Yes, it will! The end effect of the three methods: PAgP, LACP, or ‘on’ mode is the same, the etherchannel will function the same.

Guys trust me when I say the Anki flash cards are heaven sent it's worth the money

@MrTAL69 3 года назад

Very clear and concise course you have here, I'm enjoying it very much. However a couple of things to mention here. 1. Talking about load balancing in this context - while common - a bit misleading. LACP does not take into account the load on the other legs of the aggregated link, it just determines the appropriate leg to use based on the 3 named methods. EtherChannel contains no actual load balancing algorithm either. Strictly speaking link aggregation is load _distribution_, not balancing. 2. Aggregating 4 links does not strictly speaking create a single link with 4 times the bandwidth either. Again, the traffic isn't balanced, just distributed across the available links based on the named rules but without considering the existing link load. The max traffic speed between any 2 devices over an EtherChannel link = the speed of a single physical link involved in the EtherChannel. In real-life network you may well have a 4-leg EtherChannel and notice 80% utilization on 3 legs but only 5% in the fourth. Actual load balancing requires intelligent devices that constantly monitor the traffic, and re-direct it over different links in case of congestion. Just wanted to bring this up, as I've lost count how many times I've had to explain it to less-than-happy network admins. Other than that, absolutely fantastic series :-)

@JeremysITLab 3 года назад

Yeah I'm aware of how EtherChannel works. Cisco gives a pretty good explanation of how EtherChannel load-balancing works on IOS/CatOS here: www.cisco.com/c/en/us/support/docs/lan-switching/etherchannel/12023-4.html

@MrTAL69 3 года назад

@@JeremysITLab Yeah I had no doubt - just considered it worthwhile to clarifying this to the people who follow the course. Explaining this to an irate budding NetAdmin who's not happy when the traffic over his server's LACP link is unbalanced loses its appeal after the 11th time or so :-) Funny enough Cisco agrees; the second sentence in that page says "...allows load SHARING of traffic...". That's the only time, tho' - after that it's about "balancing". My best guess is that that the marketing ppl butted in. "Load sharing" and "load balancing" are two very different concepts, but one of them sounds better on the brochures...

@eternalblue4660 3 года назад

In regards to the EtherChannel flow calculations, I am assuming the more input data you provide the protocol with the more efficient its switching decision will be? This must come with more CPU overhead of course. However, is there usually an agreed upon method that applies generally to networks? Or is the decision done on a case by case basis depending on the network design/architecture? Say for example would the sweet spot generally be for most networks to not include too much input data(SMAC + DMAC, SIP + DIP, combinations of both etc) but also not leave it so scarce to the point where the protocol makes a less efficient switching decision than it could have if it was provided with additional input data? In short, is there a specific combination of load balancing options which apply generally that A) Make sure the switching decision process is as efficient as possible for most networks B) Not use too much processing power and C) Make sure you are not getting diminishing returns in terms of efficiency(The balance between CPU overhead and load balancing between the logical links). May be a tough one to answer and I may be off the mark here or missing some information but I couldn't stop thinking about it while watching this video haha. But it would be great if you could answer it or possibly provide me with some resources to follow up on. Thanks.

@st10689 3 года назад

Hey Jeremy I have two questions. 1) Some people say it's better first to shutdown the interfaces and then configure the EtherChannel to avoid any possible misconfigurations with the other switch. Do you agree? It is recommended to do it like this or it's totally fine if I don't shut them down? 2) Can you explain please what is bandwidth, throughput and speed. How are differentiate one from another?

@JeremysITLab 3 года назад

Hi Stefanos, 1) Shutting them down does no harm, so go for it! I personally haven't run into problems by not shutting them down, though. Whichever you prefer! 2) Often they're used interchangeably (I probably do so at various points in the course), but try a google search like 'speed bandwidth throughput' and you'll find some explanations better than I can give here!

Hi, At layer 3 in ip header we have a field called TTL, every time an ip packet reaches a hop TTL is decreased by 1, and when TTL is 0 packet is discarded, hence ip broadcast storm or ip add flapping isn't a thing

@JeremysITLab Amazing Video as always, but here's a question: Since There are 62 Videos each one is 30 to 40 minutes, how do you keep all that information in your brain, without forgetting what you did in the previous days, especially the configuration commands

do we have to memorise those flags' meaning in our head for the CCNA test? I think those legends would be dispayed directly in CLI no?

What happen if you configure an Ip address on one of the port-channel interface ? Will it be "s"-ed ?

At 4:58 or so, you say that layer 2 loops are made if all interfaces are forwarding. That is because any broadcast frame coming from ASW1 and out of a interface on DSW1 will be sent back through the 3 other open interfaces back to ASW1, right? And, of course also the other way around, i just need to make sure i understand it correctly.

Yep, you got it

Hey Jeremy! Dump question here, so if layer 3 LAGs are a good option to avoid broadcast traffic loops etc, then why would we even consider using layer 2 ether channels? Besides, isn’t broadcast traffic necessary at all on a layer 3 LAG? What about ARP o any other broadcast 😅so how Vlans travel from access switches using Layer 2 etherchannel through agregation switches using layer 3 ether channels where broadcast traffic is not allowed ?

34:26 do we need to know the answer of this one? Because the flags are already appearing in the summary mode
