Hi,
Can i connect 2 x 2960 stacks ( 4 switches in each stack) together ? Reason why i am asking is that we are looking replace 3750 with 2960SF and some of the current 3750's have 8 switches connected in a stack. So i will be replacing them with two stacks of 4 effectively using Flexstack.
What problems i can encounter if i do that ? i am inheriting this project from someone else but the business decision has been made to do that so i have to work with this scenario.
I was thinking on the lines that i will Connect the Master 1 of stack 1 to Master 1 of stack 2 to provide redundancy. if this is possible then can i manage all the switches via one Mgmt Ip or will i have to manage them separately... It would be really appreciated if someone can explain it more details.
I havent done this before so asking these questions to give me confidence that i am thinking on the right track...

The maximum stack size for the 2960SF is 4 switches in a single stack.
If you need to connect two 4-switch stacks it would be a normal Ethernet connection and they would remain separately managed entities.

As noted by Marvin, and which you seem to already know, FlexStack is limited to 4 member switches. You could interconnect the two stacks using MEC.
Unsure the 2960S supports it, but if they support clustering you could manage two stacks somewhat like a single unit.

Leo,
Are you getting a dollar (AUS) for each 3850 that you get sold? JK
They are nice kit (as are the 2960X), just a little bit wet behind the ears still - we ran into some problems with early deployment of the integrated wireless controllers. Stay tuned for the little brother 3650 due out soon as well.

No, Marvin. That ain't my job. LOL.
I'm just stating the obvious because I am envious.
They ain't selling the 3850 good enough down here.
Stay tuned for the little brother 3650 due out soon as well.
Thanks for this, Marvin. I'll go and dig this out. But isn't the 3650 an existing product already? Getting confused with the 3560.

Yes, I just heard today these will begin shipping this month (October 2013).
The support pages and software should be put up in the next couple of weeks. They will run IOS-XE just like the 3850s do.
