Hi Ace. I have been looking for your videos for a long time. It is great to find your videos. Thank you, Ace.
Very informative! Learn so many new things from this 6 min video. Thanks!
Exactly what I was looking for, great video, thank you.
Great to hear! Thanks for watching!
OMG! No way to explain it clearer! Thanx!
You're welcome! Thank you for watching!
Excellent !!!

Thanks, really helpful 👍
No problem! Thanks for watching!
For home network, I was going to use a 16port switch in office. Then an 8PORT switch in living room , then an 8PORT in kitchen dining as a Daisy chain.
Reason I’ll have 1cable from room to room. Then multiple available in each room off the 8PORT switches. 16port will be using most for printer and multiple computers in office. I “may”. Pull 2 of those lines (one to each of two bedrooms).
That way , lines between rooms are minimal. Once in each room, I can run them on floor bundled next to base board allowing lines/rj45s from multiple seating spots for guest.
I’m not concerned hiding them. We have long (L-Couch) and other furniture in living room .
Kitchen, run through cabinets attached to back wall out of the way and drop one rj45 down from top cabinet at intervals around kitchen counter. (Out of the way but accessible).
I’m disabled and very low income, can you recommend the best brand switch and model(s) to buy? Also for Daisy chain - how many of each type cable I need? Only last Daisy chain will be from front regular port to last switch rear port. 1gb non Poe is needed.
I have qty 1 managed 8PORT switch that was given to me. (Not used yet by me).
I will have separate router with POE 1GB PORTS for security cameras and devices to plug into. (Should I connect this router into main router directly? Or into a spare router I have first? (Any benefit doubling router up before primary modem router for security devices?)
Or
Run security switch Poe into 16port office switch to reach modem/internet that way? I though those as separate would be better going to modem.
But I am clueless!
You've got a number of questions there that are more difficult to answer without being there with you. First of all, typically you would run a POE router where the devices are that need power FROM that POE router. In other words, do you need the POE router to provide power to any devices? And if so, where are those devices? In this case, the POE router from what you're telling me is powering the security cameras. That's the first determination on where to put a POE device. If the POE device is NOT providing power (through the ports) to any devices directly connected to it, then you may want to run the POE router next to the ISP router (or main router).
As far as home or home office sized switches, any on the market will usually do what you need them to do. You don't necessarily need to even use the rear (switch-to-switch) ports I talk about in this video, unless you need every port on the front of the switch for that many devices.
Hope that helps you somewhat. But let me know if you have additional questions and I'll be more than happy to help you.
With an initial network, you can connect switches any way you want, as they will all be on the same network. With the router, just keep in mind that where you connect it, it will divide it into whatever multiple networks it has on it (or you configure on it).
Thank you so much dear technician, Tell me, Are there any differences between connecting switches using straight through and crossover method?
During the rain, The cable gets a high voltage and sometimes switches get damaged! WHY, Maybe there is a short circuit OR what!
Our access points use only 4 pins, can I use the other inactive pins as a earthing system / grounding in order to prevent the devices from lightening strikes/ short circuit during the rain.
THANK YOU,
Without actually seeing the devices and setup you've got there, I would say check the wireless APs themselves, as they should have their own ground under the UL rating without something having to be improvised. You may also set up surge protectors on the switches the APs are connected to to prevent surges from lightning or other from damaging the devices.
@@AceNetworker Thank you dear technician for your quick response, Actually,Our APs do not have have grounding cable in AC.
I am wondering if using inactive pins as an earthing system! I can connect these 4 inactive pins to switches box... !
Thank you Technician.

Hi Garrett. Question if you have time please. I have a main switch in the house and was planning on putting switches in several of the rooms in our house. So the wires going from the router are 568a as are all the current wires going to all the computers. Do I understand correctly that if I add a switch on any of those computer runs that I’d rewire those to be 568b?
That IS the case IF the switch interfaces (the physical interfaces) don't have/use MDIX. Most new switches automatically detect the type of cable you connect using MDIX, so check that those switches have it and have it enabled on all of their interfaces (or the interfaces you're using to connect the cables into) and you won't need to rewire.
@@AceNetworker Ok cool. Thank you very much for the response! Just wish I’d saved the manual 😉.
Hi ace networker, if you use uplinks or regular ports, does it should set up ip's in thats interfaces ?
Thanks for watching! No IP's will be used on Layer 2 Switches or their connections to each other. Now that is not a "blanket" answer - as you can assign a Management IP Address to a switch for use with pinging it on/over the network and accessing its management configuration.
But for the actual connections between switches, they will not need (or use) IP addresses...No.
Hope that helps 🙂
Thanks a lot and greetings from Monterrey México @@AceNetworker
@@AceNetworker Got it, that should be if you just use the native vlan 1, but what happen if you need to create and use multiple vlans? how do you should setup the uplinks port in order be able to communicate betwwen the vlans?
I’m having an issue with having multiple 2.5g switches on my home network. Have a cable going out of the 2.5g port on the modem to a 2.5g switch. Then I have two 2.5g switches connected to that modem that are in other parts of the house. Only one switch will have internet and the other can’t get an ip or not assigned an ip. And vice versus. Whichever computer turns on first on that switch basically makes everything else on the other switch not work.
Hi, and thanks for watching my channel! Without knowing all of the details of your setup, you may want to check the NAT/PAT setup on the router to make sure it is able to hand out IP addresses to more than 1 device on your network. Then you may want to manually assign an IP address to each switch for managing them. Also, once the first computer gets assigned an IP address and is connected to the internet, try to ping an external website (like Google or Microsoft dot com) to confirm it is able to ping. If it's able to ping through both switches (the switch it's connected to and then THRU the other switch into the router and out to the internet), then connectivity is not an issue, but rather IP addresses being assigned to all devices IS the issue.
So I purchased this BV-Tech 6 Port PoE switch with dual uplink ports thinking one uplink port could be used as a fail over for an alternate isp connection.
Am I wrong here?
Using multiple uplink ports on the same switch can get somewhat complex. Theoretically, you could, but there are a lot of factors to consider: Are both uplink ports on the same LAN/VLAN in the switch configuration? Are they both connected to the same router (for the ISP)? If both are connected to the same router, do they both use the same default gateway IP address?
I guess to simplify the answer (or possible solution), consider the uplink ports just like any other ports on the switch for initial considerations (what they're connected to, how the other device(s) handle traffic coming from or going to those uplink ports, etc.). Then also consider that uplink ports are primarily designed to be connected to other switches for Layer 2 traffic, unless this is a Layer 3 capable switch.
@@AceNetworker I believe my BV switch is basically a dumb switch, for lack of better words. It doesn't come with an interface for creating vlans, etc. I believe I've found an inexpensive option that does what I need it to do. The TP-Link ER605 V2 has the multi vlan interface.
Very nice video
Thank You! And thanks for watching!
That was good.
If no uplink marking/ indicator is shown, or mentioned in the packaging.... Does that mean it's a smart switch & any port will work?? I'm talking the most popular, $20-ish, 8 port gigabit, TP-Link / Trednet units from Amazon
Yeah, I think so, cause it has worked when practised irl for me
I seriously apologize for not responding sooner on this, as CZcams didn't show your comment to me until now. Yes, any port on most switches can be used to connect to another switch. The uplink port (if a switch has one and it's marked as "uplink") essentially allows all other ports to be used for connecting network devices. So an uplink port gives you another port to used on the FRONT of the switch that doesn't have to be taken up with a connection to another switch.
@@AceNetworker what if both unmanaged switch doesn’t have uplink? in my case i connected both with either cross or straight cable but it didn’t work, could you suggest what should i do please?
Can you connecting a managed switch to an unmanaged switched?
The simple answer is Yes you can - if it's for network connectivity. The only limitation you have with an unmanaged switch is you can't change settings on it (remotely or in-person). But yes, you can connect network cables between managed and unmanaged switches. Lots and lots of networks are running that way now.

You are very welcome! Thank you for watching!
@AceNetworker questions
1- does all the switches will have be in the same subnet?
2- how should be set up the switches if you need have different ip in each switch does it possible or not?
3- what about Vlans does it possible to setup in the switches and got to have communication between each others?
thanks in advance and greetings from Monterrey Mexico.
1 - All switches start out defaulted to VLAN 1, so they are all in the same subnet until you configure different VLANs on the interfaces
2 - Depending on the brand of switch, you can usually set up a management IP address in each VLAN. If only one management IP is allowed, then it's usually only allowed in VLAN 1 or you have to create the Management IP address within the subnet of the VLAN you wish to access management of the switch within. For Example: If you wanted to manage/access the switch in VLAN 3, you would create a Management IP address on that switch that is in the same subnet as what the devices on VLAN 3 are using.
3 - Multiple VLANs are usually recommended, especially if you have more than one subnet going across a switch. The Uplink port can also be configured into a different VLAN (other than the default of VLAN 1) and/or be trunked with multiple VLANs
Hope that mostly answers your questions. But let me know if I need to clarify anything there.
Thanks for watching!
Thanks a lot', your are a geniuos!
Ace please help me with an answer: If i need a redundant cable between (2) switches can i use for the first connection Uplink Port (Switch 1) to Regular Network port (Switch 2)and for the second (redundant) connection Regular Network Port (Switch 1) to Regular Network Port (Switch 2)? If not can you please suggest me a solution to have redundant connection between the (2) switches? Thanks a lot!
You can use either of those types of connections, but here's what you will encounter: You are creating a loop with 2 cables between the same 2 switches. So you'll want to change the Spanning Tree configuration settings on at least 1 of those cable connections to have a higher Spanning Tree "Cost" - This will force the 2 switches to utilize only 1 cable until that connection is not available, then it will start using the 2nd cable only if the first cable (the one with the lower "cost") is not working or connecting.
Another option is to NOT use the uplink port and use only 2 normal network interface ports, but configure both of those physical interfaces into a Link Aggregation to function as a single LOGICAL interface. Do that on both switches to have them match each other.
@@AceNetworker Thank you so much Ace for your fast response! I really appreciate your help! Do you have a video that explain Spanning Tree configuration settings or can you suggest me one? You are the best!
I don't have a video explaining the actual settings yet (working on it). But I can list an example here:
Setting the cost to 2000 on interface 1/1/1 (or the interface on the cable connection you wanted to be stand-by):
switch(config)# interface 1/1/1
switch(config-if)# spanning-tree cost 2000
Setting the cost to the default on interface 1/1/2 (or the interface(s) on the cable you want the switches to utilize primarily):
switch(config)# interface 1/1/2
switch(config-if)# no spanning-tree cost
You may have different interface numbers and you may have different command parameters, but these are some of the basic commands for Cisco switches.
@@AceNetworker Thanks a lot Ace! .. this is very helpful! ... i assume these commands will work only on managed switches right?
@@mihaitodea8510 Correct. These types of commands will work only on managed switches. Now, if you DON'T add a higher cost to one of those connections, Spanning Tree (assuming these are managed switches, or at least 1 of them is a managed switch) will automatically detect a loop created there and should technically block one of those connections until the 1 working connection doesn't work/connect - at which time it will "unblock" the blocked cable connection/interface and allow it to function.
Again, preferable that BOTH switches are managed switches, but if they're not, at least 1 of them needs to be using Spanning Tree for this to work.
Hello, I need help pls, I connected a router to a switch1 then switch 1 to switch 2 but switch 2 is not acquiring automatic IP? What do I do
So without knowing the exacts on this, make sure Switch 2 is able to ping or connect to the DHCP server on the router. The DHCP server (probably on your router) is what is "assigning" IP addresses to the devices on your network.
@@AceNetworker thanks a lot, I was able to figure it out last night, I had to trunk the port of the switch connecting to the router and trunk the interfaces btw the switches✌️✌️😀😀. Thank you 👍👍
@@Sugar_peace654hey same, what did you do? do i need to config it on pc connected to switch2???
