I have a network to install that was originally designed to be;
two distribution switchesthat are WS-C2960S-48FPD-L stacked. These are connected via two TEN Gig ports in etherchannel back to a 6513E.
The Access layer was to be 3WS-C2960S-48TS-L switches that were all stand alone, each with two, one gig uplinks one back to each of the distribution switches in an etherchannel. Now they would like the three access layer switches to be stacked. This access layer stack would have two, one gig uplinks in an etherchannel. One port of the etherchannel would land on switch 1 port 48 and the other port in the etherchannel would land on switch 3 port 48.
So I guess I really have three questions.
One can I hang a 2960 stack of three switches that are (access) off of a 2960 stack of two switches that is the (distribution)
Two Can I ethercahnnel between the two different stacks.
Third question is really configuration help.
The Etherchannel that I have between the Core 6513 E and the distribution WS-C2960S-48FPD-L is configured as follows:
On the 6513E

On the distribution switches WS-C2960S-48FPD-L

Does this above config look alright?
And would the following config work?
