Hope I explain and ask the right question. My netgear router has 1 input from modem, and 3 outputs, and is located in my living room where I have a smart tv and playstation 5. In my bedroom I have a ps5, Xbox series x, a smart tv, and eventually a gaming pc. Can I put 1 switch from the first output on my router to connect front room, and put another switch on the 2nd output line running to my bedroom to connect those devices? Im looking at getting two of the 5 port TP-link unmanaged
@AceNetworker5 күн бұрын
@emilybaxterthecartoonywitc1805 On the surface based on your description...Yes, you should be able to do that. Each switch interface will have it's own MAC address and the 3 interfaces on the router should each have their own MAC address, so in theory that setup should work.

@@AceNetworker Im sure this is a supa simple answer for you. I have 3 routers, im trying to ping from 1 rtr to the 3rd rtr but cant. Able to ping to the interface(on the 2nd rtr) closest to the 1st rtr but then it drops at that point. Do i need to configure a static route in the middle (2nd) router so Im able ping across it so I can reach the 3rd router?
@AceNetworker18 күн бұрын
@elamaroon8316 without knowing all the details (and that's difficult on yt comments), I would say Yes on the surface. Routers have to pass Layer 3 traffic, and they have to know where other routes and IP addresses are located for pings and traffic to get through. Can you login to the 2nd router and ping directly from it to the 3rd router?

@elamaroon8316 you may want to check on "IP Relay" or make sure there are no Access Lists set up on the router that may prevent pings from getting through. If all other traffic works correctly (depending on the brand of the router) IP Relay or sometimes it's called "IP L2 Relay" may need to be setup to allow pings through

@Bozzigmupp Frames are the structure for 1's and 0's sent at Layer 2 on a computer network. They are how ethernet networks communicate data across the network. Think of a frame like a conversation between 2 humans: One says "Hi, how are you today?" and the other person responds with "Great! How are you?" Those intro phrases are like a frame for a conversation to begin

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,
@AceNetworker3 ай бұрын
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.

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!
@AceNetworker3 ай бұрын
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.

@AceNetworker3 ай бұрын
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.
@mihaitodea85103 ай бұрын
@@AceNetworker Thanks a lot Ace! .. this is very helpful! ... i assume these commands will work only on managed switches right?
@AceNetworker3 ай бұрын
@@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.

@AceNetworker4 ай бұрын
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!
