Hi George.

I assume you will be using 3750x as core switches.

For redundancy, I would suggest Hot Stand Router Protocol (HSRP), having one core switch as active and the other one as standby gives you high availability and also redundancy, let me share with you the following links about HSRP:

But first, put the 3750X into a stack.  Next, you send two uplinks from the 2960 or 2960S to the core switch and configure etherchannel on both the floor switch and the core switches.

2960/2960S do not need the command "switch trunk encap dot" because dot1q is the only (and default) option.

You cofigure a port for etherchannel like this:

interface range G0/1 - 2

switchport mode trunk

channel-group mode ON

On the 3750X, it'll look like this:

interface range G1/0/24 , G2/0/24

switchport encap dot

switchport mode trunk

channel-group mode ON.
