Free CCNA | Configuring EtherChannel | Day 23 Lab | CCNA 200-301 Complete Course

[@Ironbull200]

I tried to complete this Lab before I watched the video and I managed to do it. But I must admit, I found it quite challenging to not forget anything and keep track of all the different configurations necessary. This was a great exercise to solidify the material learned through the lectures. Thanks so much for building this course and providing it for free!

Question mark was my friend for this one. I'm going to struggle to remember them by heart (so multiple choice would be hard) but they did say labs on the CCNA allow you to use the question mark. At the very least I can do it using that tool.

If anyone's having issues with an error on 3. where after you run the command no switchport and it gives you the error "must be L2 or L3, or vice versa" you need to configure the Port channel itself with no switchport and it'll let you change it. Ran into this issue myself.

[@lja1993]

While doing this lab I noticed a slight discrepancy between yours and mine. I didn't have to configure trunk encapsulation on the L3 switches. Would this have been a Packet Tracer update that maybe made that model of switch behave differently?

[@Ironbull200]

I noticed that too. I assume the Switch model somehow got updated, so that it only supports dot1q. Like Jeremy said in the Lectures, configuring encapsulation is not necessary if the switch only supports dot1q.

I was not able to set the encapsulation like Jeremy did at 5:10 mark in packet tracer. I can only say that its that mose likely they updated packet tracer and this is no longer possible. That said my encapsulation was set to dot1q by default for me so worked out in the end.

[@dmitrikazantsev3692]

When I decided to do the lab once again and this time from scratch, I've got completely stuck with multilayer switch as Packettracer kept reporting that DSW is powered down and wouldn't give access to CLI. I did a google search and discovered that actually you have to manually drag and drop icon of a power supply over icon of actual switch device with your computer mouse. Twice. Well. That was a creative way for Cisco to show who the real boss is here. :) Since I cannot imagine a live human being configuring a device which is switched off (no lights, no sound, no fans, all dark and cold), but I was glad they didn't ask me to bolt the rack to the floor dragging 4 blots and 4 washers with my mouse before giving access to CLI. ;) Great series Jeremy!

[@saitejaprathipati3988]

whats the power supply dude..? i mean is it a battery or something else..?

[@dmitrikazantsev3692]

@@saitejaprathipati3988 Cisco Packettracer in its desire to be as realistic is possible considers simulated equipment to be turned off and doesn't allow any CLI with it until you ~"physically" install~ power supply units. To do this you need to drag and drop two icons of power supply module using your computer mouse in your simulation, which I see as a joke.

[@Judicial78]

I always try doing the labs before watching the lab video, I had my interface range up and set my etherchannel group, then instead of switching to the group I just did switchport mode trunk from the interface range and it formed the trunk without needing to set the encapsulation type. edit: so I went back and tried doing it your way and the l3 switches dont have switchport trunk encapsulation command.

[@StylistecS]

Ran into the same problem. It didn't reject my sw trunk command.

[@kesicidelici61-bp5oj]

that is right! also modern L3 switches dont have ISL option, they say.

[@jordanrosemanmusic]

I got really confused when configuring ip routes. I was overthinking the preconfigurations and thought I had to configure the vlans to the trunk link on g1/0/3 & g1/0/4. I now understand that I was confusing myself. The vlans + default gateways were already configured and all I needed to do was configure the routes between DSW1 and DSW2. I need more practice with Multi-Layer Switches.

[@lim9975]

Hi Jeremy, is encapsulation ISL forming a trunk too as dot1q? Why in Task 2 question 9 asked for configuring the Port-Channel 1 interface on DSW1 and DSW2 to trunk unconditionally if ISL able to form a trunk and when we need to use ISL or dot1q in this case?

[@JeremysITLab]

Yes, ISL forms a trunk too. However dot1q is preferred because it is an open standard (only Cisco devices can use ISL). Even many modern Cisco devices can't use ISL.

[@lim9975]

@@JeremysITLab Thanks for your answer!!

[@johnconnor9787]

Just one little question to clarify: If layer 2 Switches are not aware of IP, how can they load-balance etherchannels based on IP?

[@JeremysITLab]

It depends on the switch model some older ones might not be able to. But most switches these days have both Layer 2 and Layer 3 functionality.

[@AndriyKerez]

@@JeremysITLab I was wondering about the same... What would happen, if ASW1 or ASW2 is not a multilayer switch , and the load-balancing was set to src-dst-ip?

[@warcryplayer5751]

I think, it is because they're not using a routing protocol or static configured route, they're using an algorith to forward traffic in this case they load-balance and that algorithm use the hash which is found in the last bits of the source and destinantion ip addresses and they perform a xor operation on those last bits. (I think that the algoritm is not important for the exam)...The fact that layer 2 switches are not able to route packets doesn't mean that they are not aware of IP addresses. They keep using IPs addresses for administrative reasons (like in Telnet or SSH) or maybe they use IP addresses to perform a local algoritm, just like in this case...As far as i could see packet routing and load-balance are two different processes.

[@arsenmkrtchyan4832]

06:10 I thought that if spanning-tree type is shared then it should be operating in half-duplex. But not in this case, isn't it?

[@JeremysITLab]

Correct, it's not half-duplex.

[@GerardAlastuey]

Why the type link between ASW1 and DSW1 is shared? Shouldn't it be p2p as it is between switches?

[@Анатолийскачать]

@thetoxicmetalhead Did you pass the exam?

[@unrealriot]

Hi Jeremy, for load balancing regarding real world applications, are there any specific cases where you need to set inputs to source addresses only or destination addresses only besides configure to "src-dst-ip" ?

[@JeremysITLab]

I've never done it, but I guess there could be situations where, depending on the traffic patterns in your network, traffic would be more evenly balanced using src-dst-mac, for example.

[@Guitarrr01]

I presume the L3 switches were changed at some point since the video was created and they only support dot1q and not ISL so no need to specify anymore but that will definitely throw you off a little.

@@JeremysITLab Thank you!

[@shw256]

Thank you for this lab. Regarding the link between DSW1 and DWS2, which we want to configure as a layer-3 EtherChannel link: In Packet Tracer, if I enter the `no switchport` command in the port-channel interface configuration mode (but NOT in the interface configuration mode for the underlying physical interfaces) and do all other configurations as in the video, then the pings from the PCs to SRV1 still succeed. Will this also be the case on actual Cisco devices, or is this a Packet Tracer thing? Note: The output of `show running-config` differs with the two approaches. Applying `no shutdown` to the port-channel interface only, we get (for DSW1) ``` interface Port-channel 2 no switchport ip address 10.0.0.1 255.255.255.252 ! interface GigabitEthernet1/0/1 channel-group 2 mode on ``` Applying `no shutdown` to the physical interfaces only, we get ``` interface Port-channel 2 no switchport ip address 10.0.0.1 255.255.255.252 ! interface GigabitEthernet1/0/1 no switchport no ip address channel-group 2 mode on duplex auto speed auto ```

Hey Jeremy, I was wondering why the etherchannels link type under show spanning-tree are listed as shared? If its a logical port shouldn't it be p2p? Or is this a PT bug?

I don't understand what is the dynamic thing when you use LACP or PAgP because if a I create in on site of the switches the port channel I thought that automatically the other neighbor switch connected with the same interface that has a port-channel in the configure switch also going to generate automatically this Ethernetchannel in this neighbor switches.

[@JeremysITLab]

I haven't tried it, but I think you will have to delete the current port-channel and then remake it. For example: SW1(config-if-range)# no channel-group 1 mode desirable ( *removes the interfaces from the PAgP port-channel* ) SW1(config-if-range)# no interface port-channel 1 ( *deletes the port-channel interface* ) SW1(config-if-range)# channel-group 1 mode active ( *configures the interfaces in a new LACP port-channel* )

@@JeremysITLab I tried that before but wasn't able to delete the channel. Probably because I didn't use the (no interface port-channel 1) command. I think it should work now. Thanks for the help Jeremy, you're the man.

Does configuring different load balance mode on a single link is allowed? for example, one end is configured with src-mac and another end is configured with src-dst-ip.

[@JeremysITLab]

Yeah that's allowed

[@kenny-et2dc]

Please what's the default gateway IP for PC1. Im sure it uses the DSW1. How was it configured on the multilayer sw?

[@mohamedoueslati4822]

Hi ! there is too boson, one is practice exams and other network simulator, is the practice exams suffcient or you reccomend that we buy both of them ? thank you,

[@JeremysITLab]

If you can only get one, I definitely recommend the practice exams!

[@mohamedoueslati4822]

@@JeremysITLab Okk thank you !

[@countertop5952]

One question; I understand that all configuration done on the Port-Channel interface will be applied to all member interfaces, correct? The only thing you should configure beforehand is if the interface should be layer 2 or 3, but for example tagging vlans, changing native vlan, etc can be done only on the PO interface? I only ask because we didn’t change any config except for make the ports trunk in L2.

[@martinflavell3045]

love you Jezza!

Please on this video how do I configure the gateway for pc 1 I don't really understand

[@JeremysITLab]

The default gateway should be the SVI on the layer 3 switch.

[@aussietx9403]

I noticed that as soon as the load balance method was changed to src-dst-ip I was not able to ping anymore from PC1 to the server. Put it back to src-mac and it worked again. I suspect that is just another packet tracer limitation.

How was your pace with these lessons guys? One a day, multiple a day, space out throughout the week while using flashcards?

[@scientiest12]

One lesson each day with detailed notes from the lecture of everything new to me, review flashcards after the lecture, then do the lab. Try to do these 3 at minimum each day. If you have time remaining, you may watch another lecture as well

[@dhanajon5528]

i try to do 1 lecture video, 1 lab, that day's flashcard and previous days flashcards a day, but I must admit, it is getting harder. like this topic i couldn't do in a day

[@scientiest12]

@@dhanajon5528 after reaching certain days, you have to stop revising the entire deck each day. Just try to do your daily deck each day, and review 1-2 previous decks of important topics every alternate day, that way its easier to stay on top of it.

[@big.atom37]

Wait, don't vlans operate on level 2? Why are IPs assigned directly to the vlans on DSWs rather than to their interfaces? Also ASWs are Layer 2 switches. How do they load balance based on IP? I'm somewhat confused.

HELLO Jeremys merry christmas , just i need to know , do you really do discount for exsim product ? and i need to know which exsim is suitable for ccna exam becaus there are two exsim in the list , the first one calling EXSIM-MAX for AWS CLF-C01 , and the other one calling EXSIM-MAX for AWS SAA-C02 .which one better can i use to pass CCNA exam? thank u

[@JeremysITLab]

Merry Christmas! Boson is having a sale until the end of this month for 25% off, you can use the code MERRY20 to get the discount. Both of those ExSim are for AWS, you should get ExSim for CCNA, here's my link: jeremysitlab.com/boson-exsim

When i type show spanning-tree. It only shows the fastethernet ports and not the Gigabitethernet. Although ive connected the cables on the gig ports just like in the video….whats the Solution?

It's really hard to remember to all these commands. I've a question that to get into the cloud or network firewalls, what are the concepts of networking or ccna should i know thoroughly Jeremy...?

[@awaken477]

Jeremy, why do we needed to enable switchport trunk encapsulation dot1q on Layer3 switches, when enabling trunking on them but not on Layer2 switches on the other side ? Is there a difference ? I did the lab by myself but I had only one mistake and it was that encapsulation on L3 Switches...Cheers

[@JeremysITLab]

Some switch models only support 802.1q encapsulation, so you don't need to specify it. On switches that support both 802.1q and ISL, you need to specify which to use.

[@gary_lam]

I dun understand why "switchport trunk encapsulation doq1q" is used to setup on DSW when ASW dun need ?

[@Awed1b]

As always, this was real helpful, clear, and easy to follow. Thank you! Q. If I am setting up an office remotely, can I pre-configure the switches, then once they are set-up, have someone plug in the connectors? If so, is there any reason to not do it this way? (Day 23 Lab)

[@Holdivar]

Not sure if this is a thing with Packet Tracer, but when I set up the trunk I just entered the command while configuring the interface range g0/1 - 2. It still configured PO1 as a trunk. In a real world scenario would it be different? Thank you for your videos! They've been great.

[@marekkordas740]

Hi @Jeremy's IT Lab, First of all thank you for this great course, they way how you doing it is great really appriciate your work. I have one question. subscribed to your mailing list got confirmation email but haven't received any flashcards or packettracer lab files. is it still live or should look for them somewhere else?

Hi Marek! Send me an email at [e-mail]. I’ll get back to you later with the links when I get home.
