3560 IP Base vs 3750 Stackable

I have read many sheets on the 3560, we currently use them. We do have a situation where we need Fault-Tolerance built into our environment. I have looked into the cluster feature of the 3560 but it would seem that is for management only. I see the 3750's are stackable and that is the main advantage over the 3560's. Does anyone know if it is possible to 'stack' the 3560's in a similar fashion? I dont want to scale these down to Layer 2 because we are using the IP Base features. Any ideas on this? Does anyone have pair of 3560's running A/P?

It would appear as if this is not possible as I have read through countless tech spec's.

Unfortunately, the 3560 series switches are not stackable, and that is actually the only difference between the 3560 series and the 3750.

As Reza noted, the 3560 can not be stacked.  For redundancy you would either need to do "traditional" L2 loops, and use a STP to control them, or you might use FlexLinks.

BTW, for original 3560s there's a "special" 50CM "stack" cable.  Basically, it's a less expensive way to use gig SFP ports between 3560s.
