11501s and 3560

[josephschung]

Dear Sir,

From the attached diagram, does this design work?

2 x 11501s

2 x 3560

No heatbeat between 11501s.

Thanks.

2 x 3560

Yes. CSS (as all cisco switches) know STP. Communication between CSS's is possible without ISC (inter switch link) in some types of redundant configurations.
