[@Dbdjabsjsiifiwb]

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.

[@abdelrahmanelsherbiny8833]

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]

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.

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.

[@dylandahlson4077]

At about 13:50 regarding Non-IP: Source XOR Destination Mac Address did you mean to say no MAC address instead of no IP address when not encapsulated by an Ethernet frame? I can’t think of a scenario where an Ethernet Frame wouldn’t have a source or destination IP address inside (from the IP packet) but maybe I’m not following correctly

[@JeremysITLab]

I said 'if an IP packet isn't encapsulated inside the frame'. In that case there is no source/destination IP address to be used. If it's an Ethernet frame, there will always be a source/destination MAC address.

[@konefine3626]

Great thanks to you Jeremy. I have a question: If we configure EtherChannel statically with mode "On" being a connection between 2 switches , this means that the switchport mode trunk must have been configured previously?

[@eternalblue4660]

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.

Hello Jeremy, do we do load balancing when we use layer 3 switches?

[@chrisfoster3772]

Hi!!!! 🤠

[@unrealriot]

Hi Jeremy, I'm curious on the loading balancing conf. I understand that ethchannel can load balance either the source or dest, or both of them. Why did Cisco use 'XOR'? As I understand XOR is exclusive OR, which means you either have this or that, but you can't have both.

[@JeremysITLab]

Hi Byron, I hadn't thought about that so I did a Google search, here's a nice explanation: 'The etherchannel load balance is some sort of a binary xor computation. This means that the result of the xor computation selects the output link to use, it is not round robin. As an simple example, if the xor looks at the very last bit in the source and destination mac address and found this. last bit of source is 0 + last bit of dest is 0 then xor gives 0. If sou is 0 + dest is 1 xor gives 1, if sou is 1 + dest is 0 xor gives 1, if sou is 1 + dest is 1 xor gives 0. Then taking the above and put streams with xor 0 to port 1, and streams that gives xor 1 to port 2. This means that in theory, Your two streams kan be put on the same port.' Basically, the XOR gives a 0 if a bit in the source address matches the same bit in the destination address (0-0 or 1-1), and gives a 1 if a bit in the source address doesn't match the same bit in the destination address (1-0 or 0-1). I assume it compares all of the bits of the source and destination address, and the resulting series of 0s and 1s is used to assign the data stream to a certain physical port.

[@giorgioamato6176]

Hi all, can someone explain me why with routed ports (multilayer switches) there isn't the problem with broadcast storm? I understood no BDPU frames are sent between switches for STP, but hot is this related to to broadcast storm problem? Thanks in advance

[@isheep9025]

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

[@comraede]

Quiz 2, I am wondering if we really need to know these config flags by heart for the CCNA? Have you experienced any questions like that on the exam? Great video as always!

[@eyobhaile4557]

First I would like to thank you for your lecture. Q1. can we configure LACP & PAgP on different Etherchannel? if yes, how would the load balancing mode we use?

[@MrTAL69]

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]

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]

@@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...

[@afkar_zz1680]

Perfect explanation

[@Melchizedek_]

There is smthng I've seen. I think when you use the command 'channel-protocol ?' and you choose the protocol you prefer, (ie; LACP or PAgP); the options should be minimised when you issue 'channel-group 1 mode ?'.

Why do we need etherchannel for multilayer switch ? since multilayer switch doesnt create broadcast storms right?

Multilayer switches can create broadcast storms just like a Layer 2 switch, their Layer 2 ports operate just like regular switchports. However, the purpose of using Layer 3 EtherChannel is to increase the bandwidth of a connection between two devices.

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 ?
