*** Good to know stuff *** Tagged = Switch to Switch connections. Untagged = Devices(WLAN, Servers, Printers, VoIP) Port Enabled = if there is a device connected Port Disabled = if there is nothing connection on the port. *** *** *** *** I changed settings here and there for accuracy, but I referred a few other users' comments, mainly @handcraft0093 and @1stAid for their easily understandable language. Thanks @AntonioTech for giving your approach in figuring out "how to configure?" and Congratualtions! on your Net+ cert, job well done! BTW, I am very new to this IT Networking, so you might see something wrong in the configuration above. Please feel free to point it out with a bit of explanation. That will help me and other users. :)

I am just thinking, on switch 3 port 4 does it need to be tagged as there are 2 vlans going into the port?

Looks solid, but Switch 3 PORT 4 needs port tagging enabled. How else will the switch know what traffic belongs to which vlan when both the VoIP phone and the desktop share the same port?

Hi everyone, Apologies for writing so late. I've been very, very busy. OK, please remember that when you start your exam, they WILL HIT YOU immediately in the beginning with the SIMs! It was the same with me. I got these SIMs: Question #6Topic 1 (Wi-Fi configuration), Question #43Topic 1 (subnetting) and this one - Question #347Topic 1. The first 3 questions of the exam were the SIMs from here and one of them was this one. I was so frustrated when I saw how "lucky" I got because of this SIM. However, I didn't panic and neither should you. SKIP THE SIMs! Leave them for last but make sure you have time to deal with them as well. I went through all questions to the end and then started the easiest SIM. This one I left for last as I knew it would take me a lot of time because I literally checked every single port on each switch and then it hit me! I found the solution to the SIM that I could not find anywhere online :)

SW1, ports 5 & 6: You must configure both ports with the same VLANs and settings. Remember that these ports connect to ports 1 and 2 on SW2. Take a look at what devices are connected to SW2 because you must tag the appropriate VLANs on all connecting ports between the switches: SW1, ports 5 & 6 and SW2, ports 1 and 2. In other words, the types of devices you have on SW 2 will define what VLANs you will have to configure on BOTH SW2 (ports 1 and 2) and SW1 (ports 5 and 6). Since SW2 has PCs, a printer and 2 x Wi-Fi APs, you need to configure the following VLANs on ALL of the following ports: SW 1, port 5 and 6 - VLAN 60 (printers), VLAN 90 (servers also because client PC1 and PC2 most likely will have to access the servers as well), VLAN 120 (wired users), VLAN 150 (wireless) SW2, port 1 and 2 - apply the same VLANs and settings here as the ones above.

ALSO - please remember that you MUST ENABLE (Select "PORT UP"!) the active ports and also DISABLE ("PORT DOWN") the inactive ones - no matter which ones you will get on your exam as inactive, or not being used. Disable the unused ports. For the speed on all ports I chose 1000 and for Duplex I chose FULL on all ports. CORE SWITCH: I clicked on ports 1 and 2 and saw how they were configured. Remember this one because this is a HINT on how to configure ports 1 and 2 on SW1 :) I saw that I must tag ALL VLANs on these two ports on SW1 as well because, remember you are working on the Core switch which is connected to SW1. Once I saw their configuration and what tagged traffic they had, I realized how I had to configure ports 1 and 2 on SW1 so I continued to: SWITCH 1: First of all. I clicked on every single port just to see how they were configured and saw that I had to configure ALL OF THEM! Don't panic, all is good.

so you tagged everything based on the tags on switch 1 port 1,2? or did you just leave those tagged and the rest untagged.

Thank you for sharing your solution. I just took my test today. Inspite of your warning LOL, I was shocked at tthe fact that my first 5 questions were related to SIMS. I didn't pass but I will know next time. I'm going to have to do the SIMs first and then catchup with the other questions instead of the other way around. It was only 70 questions too! which I was glad about!

This SIM looks very complicated, as it did to me before the exam and especially while trying to find ANY explanation anywhere and didn't, but it is not complicated at all. Since they did NOT allow me to have any pen and paper which I needed for the subnetting and SIMs like this one, you must make sure you configure and TAG the correct VLAN on each port and the VLANs given in the question: VLAN 60 = printers VLAN 90 = servers VLAN 120 = wired users VLAN 150 = WLAN (wireless LAN) VLAN 220 = Voice/VoIP (you may face either of these) IMPORTANT NOTE: Please be careful because the ports and switches I will describe may NOT be the ones you will get on your exam. I will just explain what I had to do but the logic is the same for all other tasks. VERY IMPORTANT: Please remember that for any change you do on any port YOU MUST click on the "SAVE" button! Otherwise you have done nothing! It happened to me and what saved me was that, after I finished configuring all ports on all switches, I checked them all again - 2 times!

VoIP phones often use tagged VLANs for voice traffic and untagged VLANs for data traffic, that's why my answer for Switch 3 Port 4 was somewhat different. (My idea maybe wrong but I am sticking with it) I don't see the need for placing VLAN 150 (WLAN) for Switch 3 because I consider the laptop (Switch 3, Port 6) as connected via Wired user Feel free to respond if you have a better answer or if you think I have mistaken on how I understand it. Our goal is to help everyone and not to confuse our fellow certification takers.

This question is stupid in that it doesn't specify if the connected devices are vlan aware or not. If the devices are oblivious to 802.1Q the ports they connect to must be access ports. Otherwise the ports can be all configured as trunk ports. The question also does not specify if the devices connected to each different switch require communication with each other or not. All in all, whoever wrote this wrote it half drunk, like most of the other questions in this exam

Just to check I understand... Enable all connected ports and disable unused ones. Enable LACP between connected switches ONLY. For VLAN, copy the VLANs from the settings on the connected switch. E.g. for switch 1 port 5, copy switch 2 port 1. Speed 1000, full duplex for all. Is that right?

Correct me if im wrong, A quick summary: All connected ports are tagged with lacp to create ports on different switches working together. Ports that have devices or connected to other ports must be configured as enabled, if not, otherwise disabled. Connected ports share the same vlans that come from devices to the subsequent ports on the switch.

I'm bit confused here. So for swtich1 port5,6,78, do we need to add Vlan90(servers) as servers connected to ports on switch 1 or do we only need to care about the Vlans for what is connected to switch 2 or swtich 3 for the VLANs

I could be wrong but when multiple Vlans even if not connecting to another switch are traveling through a port doesn't it need port tagging(Trunking) such as SW3 port 4?

To explain it as simple as I can. Tagged = Switch to Switch connections. Untagged = Devices(wlan, server, printers, etc) port Enabled = if there's a device connected. Tagged Connections: Switch to Switch Core to Sw1 = All tagged VLAN+LACP. Sw1 to Sw2 = Tag all necessary VLAN connected to Sw2. Sw1 to Sw3 = tag all necessary VLAN connected to SW3. Untagged Ports: Depending on which device, select the correct VLAN and untagged. +port enabled. LACP Disabled. Disable ports = no device connected. For Cisco folks Tagged(trunk), Untag(Access). LACP(Etherchannel).

"Only make necessary changes to complete the above requirements" My take on this. Only the trunks need to be tagged but you do not have to add all the VLANs into it. Leave it as unselected and by default it will forward all the VLANS to the other switches. The SIM looks complicated but it's actually simple. Let's not overthink it. sw3 port 8: Vlan90, untagged sw3 port 7: Vlan60, untagged sw3 port 6: Vlan150, untagged sw3 port 5: Disable sw3 port 4: Vlan220,120 untagged sw3 port 3: Disable sw3 port 1,2: Native Vlan, tagged, LACP sw1 port 8,7: Native Vlan, tagged, LACP sw1 port 6,5: Native Vlan, tagged, LACP sw1 port 4,3: Vlan90, untagged sw1 port 2,1: Native Vlan, tagged, LACP

native VLAN (vlan 1) passes all vlan traffic by default on trunked ports. I think El cabron is correct here.
