How to configure an iStack Ring topology?

Latest reply: Feb 12, 2015 02:33:47 3995 4 0 0 0


I have 4 CE6810 that I want to configure in an iStack. I have followed the doc but I'm not clear on how to configure the stack ports.

The reason its a bit odd is that I have 2 switches in one building and 2 switches in another buiding. The two (in each location) that are located together will be connected by two DAC cables, and then those two locations are connected by 2 10Gig. (see the attached image)

How should I best configure that?

e.g. Should I make the fibre links in a different stack interface  

Thanks, Simon

The 4 switches are in two buildings, you need to use fiber to connect them. it‘s better to use the same link bandwidth in stack connection.DAC or fiber are the same.

Thanks for that.

At this stage I don't have enough fibre cores for 4 connections between the buidings (unless I change to bidi sfps).

Will it be a big problem if I only have a single fibre between the two switches? If I do that am I better to change to a "chain topology"?

ring topology is better ,if the quantity of the switch is more than 2.

there are only 2 connections between the two buidings , it is ok ,the bandwidth is only 10GE.

I think its better to establish 2 stack system ,in different building, only my suggestion.
