Help with 8 switch in a ring topology

bingo600

I read the drawing as each floor (switch / stack) having a fiber comming from "top" , and another going to the one "below".

So each switch have 2 fiber connections , that would make a single floor failure survivable , except lowest (SPOF) , that feeds both paths.

Edit :
I read the 2 "boxes" on each floor , as representing the fiber interfaces in same switch/stack. Not 2 separate switches.
Else that drawing makes no sense.

Well that makes much more sense ;) heheheh

I was thinking the same thing until mentioned east and west.. So I was thinking they were 2 switches one on each side of the floor ;)

That would leave some (most) IOT units "speachless"

But now that you mention east/west ... 100/200.
I hope not ..... Unless he's linking east/west via copper , and this is just showing the fiber patch.

Exactly - which was like what... So yeah if connections off the same switch on each floor then yeah makes sense and you have 2 paths in case of problem with 1 of the switches..

With very low bandwidth requirements - nothing wrong with doing it that way I guess. I would still have runs to each switch (if possible)..

They prob haven't got the fibers for it.
This is prob. an addon , and most fibers are reserved/used for other stuff.

See my edit in the post above ...
You made me doubt now ...

there is 1 switch on every floor. port 25 go to the switch below, port 27 go to the switch on the upper floor.

.100 ----copper ---> switch <---copper------ .200 port 25/27 up/down fiber
i will add a second switch to the SPOF

they are preparing all the switch in a lab to take the test and the first configuration

@kiokoman
So everything will reside in the 172.16.x.x/16 range , including switch mgmt ?

All in a single "default vlan" ?

@kiokoman

Is this a "floor layout" ?

Made with the Free drawing tool - Dia - http://dia-installer.de/
Quite intuitive , I installed dia + dia-shapes

@kiokoman

Does that mean there's 3 switches on each floor ?
The "Red dot" fiber connected switch , and then the copper connected IOT switches 100 & 200 ??

i selected a random picture from your program...
there is 1 switch x floor

Ahh so that was just a "Dia drawing test"
