Advice on connecting two ethernet switches together

36 replies
Found 10th Sep 2010
Hi i have just bought 2 netgear GS608. What i would like to do is have one switch downstairs and one swicth upstairs and then run cables to all my devices from those switches.

Will i be able to do this?

If one switch is connected to the the modem, will that give all other switches internet access?

Will i lose speed doing this?

Thanks in advance for your help, as just trying to wire it all up.

I have done this, mine goes....

Router to switch - switch to bedroom 1, switch to bedroom 2, switch to bedroom 3, switch to front room.

In the front room the cable goes to a switch, which then goes to BluRay, revo, xbox

All works great, I get a solid 8mb connection and can stream 1080p content to all of the rooms from the pc in bedroom 2.

I only have one gigabit switch, so the whole network is 100, I was planning on upgrading the router and second switch to gigabit, but at the moment I can't see the need

Thanks for the advice, so does the router only go to one switch ie

Router --> switch 1 ---> PC, PLaystation
swicth 1 --> switch 2 --> PC, XBoX, Wii

Yes basically one cable from router to one switch, from that switch to all stuff downstairs, then another cable from that switch to second switch and connect all the upstairs stuff to that switch.

Yep, both my router and switch 1 are downstairs in a cupboard, then switch 2 is behind the TV.

Doesn't matter where they go, but yeah as you said would work fine. Except i don't believe the Wii has an ethernet port...

If you say 'Switch' too many times the word loses all meaning......

but which switch do you switch to switch all switches on, is it switch 1?

Thanks guys, last question on checking the net it says that some switches are ok with standard cables whereas others need crossover, will it be ok to use standard cable for this

Cheers

To avoid any issues, just make sure you only connect your switches in one long line, not a circle.

e.g join switch 1 to 2, 2 to 3 and 3 to 4 but don't connect switch 4 back to switch 1.

Also, any more than 8 switches can be problematic on cheap kit.

Should be in the manual for the switch in question. (Shouldn't be a problem modern switches)

If not just stick in crossovers and the switches will sort out the traffic.

You'd be lucky to find a switch that doesn't auto-x these days, or have a button for the purpose. Any 1000Mb switch will auto-X, 100Mb will likely have a switch.

Some switches may have a designated "uplink" port, which is preferred when connecting to other switches and will make the setup more efficient.

with todays modern domestic switches, this is not necessary because spanning-tree should kick in

Arrggghhh, stop saying Switch!!!!!!!!

Yes, I know all about STP.

1) Don't connect them in a circle - in case your cheap switch doesn't support STP.

2) Don't daisychain more than 8 - in case it does

well the OPs switches don't support STP, pretty lame

anywho, don't have a cow man, if you know about STP cool

you can daisy chain more than 8 cisco switches got a chain of thirteen....................

Yeah, I said "cheap" switches :O)

Proper managed switches can obviously manage this just fine.

Which word should we switch to?

its a bit difficult considering the job I do, infact impossible 418 switches i look after

Hi Guys

I have just set them up, the only problem i have is that they only connect at 100mbs instead of gigabit, anyone know why

Is your router and both switches gigabit? What cat cable are you using?

Original Poster

Cat 5e, my router isnt gigabit, however i get gigabit connections from my switch to my pc and from my other devices as they show up green, however the ports that the switches connect to are orange (100mbs). Should they be connected to a specific port

Thanks

I always thought the network is limited by the slowest part, ie your router.

But the other guys in this thread know far more than me about it

Original Poster

other stuff is connected at gigabit speeds but just not the switchesm ive been reading something about up-link but cannot understand what it means

List the equipment you have and what speeds they are connected at.

e.g.
PCSwitch 1 1000Mb
Router Switch 2 100Mb

etc.

What make are your switches?

Original Poster

Switch 1 downstairs router into switch 1, 100mps
Qnap into port 2 1000mbs

Switch 2 connects to switch 1 port 3, 100mbs
Port 1 on swicth 2 connects to pc 1000mbs

Thread hijack alert (Apols OP!)

So I have a Netgear ADSL 4 port modem 100Mb Obviously any machines passing data through this will be limited to 100MB whish isnt a problem, since its just the net.

However, I've too many devices for an 8 port gigabit switch. I was looking at getting a 16 port, but much more expensive. Also unsure on managed and unmanaged. (In real terms - what it means in practice!)

I'd like all devices to be able to communicate gigabit (internet excepted)

I know I could buy 2 8 port switches... but would it be better to daisy chain? I'm thinking if they both come off the modem, then ALL communication between devices on each, will be slower.

So not sure.. should I be looking at biting the bullet and going for a 16 port.. of can I use 2 8ports without any ill effect?

All cableing is just Cat5e, but nothing too long, so shouldnt be an issue.

Depends on how connected eg PC 1 with a 10/100/1000 NIC connected to say a netgear gs108 (Gigabit) 8 port and any PC's / devices that are also 10/100/1000 will be able to TX/Rx between them @1000 (modem router connected to switch only facilitates internet connectivity between anything connected to the switch

Out of interest what are your 16 devices?

I have 2 Netgear gs108's had them few years 1 downstairs/ modem router connects to 1 port xbox ps3 PC's downstairs connect to the next 6 the 8th port connects to another gs108 upstairs which serves all the other computers/ xboxes ps3 etc (wasted on xboxes though as they are only 10/100)

So if I change one of my switches to gigabit it will all be?

Data will go from pc to switch, to switch, to pc in front room. It doesn't matter that the router isn't?

Thinking about it the revo probably doesn't have gigabit, I need to stop trying to spend money!

both switches need to be 10/100/1000

Oops.. thats 21 ports needed! All cabeling is in line and the computer room has a 16 port connector on the wall (with cables hidden behind and into the ceiling for distribution.)

Obviously all are not required at the same time.

Yeah, one is, the other is only 10/100, not sure i'll see much benefit though

Guys

any other advice, i cant get the two netgear g608 to recognise that it is 1gb. The lights go green to show connections that are 1gb, however it stays orange, is there certain ports that the switches should connect to ie. first port and last port.

Really want to try and sort this so would appreciate any advice you may have

Thanks

cat 5e cable at least and left led is 1000 on the gs108 properties of the hardware in PC needs to be set to 1000 and optimise for throughput if you can also instead of AUTO you may need to select 1000 full dup as auto negotiation sometimes screws up yellow on my gs108 is collision

Damn, I hate thread hijackers - start your own!

Back to the OP's issue, above, clearly we can see that switchLY 2 is happy to connect at 1000Mbps - the PC does this. We also see that switch 1 will connect at 1000Mbps to the Qnap - so that is also 1000Mbps ready.

But the "backbone" connection, between the 2 switches, is only connecting at 100Mbps, not 1000Mbps.

Try swapping that cable for one of the ones that you know is working at 1000Mbps.

My honest guess? You're using a long cable between the 2 switches to support 2 rooms at a distance from each other. It's the only long cable you have, so you can't try another, but it's faulty.

Move the switches into the same room, join the 2 switches together with a working 1000Mbps cable and prove your fault. Then make up a new cable.
