  1. Hi Zaman,

    Switch virtualization is great for redundancy but it also simplifies your switching a bit. You’ll have less spanning-tree to deal with since all switches in the stack are one “logical” switch.

    What you use on the access layer really depends on your design and your budget. Normally we do have redundant connections from the access layer to the distribution layer.

    That’s something I will cover once I start with my Nexus material. Here’s quick example though:

    With VPC, you can configure a port channel on those Nexus 2000s with the physical links that connect to the 5000 switches. From the 2000’s perspective, it will appear as if it’s connected to a single switch.

  3. Hi Rene,
    this is very useful article, and it’s very important topic…thanks

    In part of your discussion, you note that “When one of the distribution layer switches fails, the other one can take over. We don’t have this luxury in the access layer…when either of the switches fails then the other one can’t take over. One way of solving this problem is to create a logical switch.”

    From what I’ve seen, using stackwise still doesn’t provide redundancy at the access layer. Let’s say that the third switch in the stack dies. All users that are plugged into that third switch are now dead in the water, right?. I don’t see how stackwise is
