I'm working on a project that will at some point be using 2 x 5020 Nexus switches and 12 x 2248s. I've never worked with the platform before. The 5020s will be connected together and the 2248s dual homed to the 5020s. Is it possible to cluster the switches to act as one large stack? I can't seem to find any reference or config guides for this config on the Cisco site. Any help would be appreciated.

What you are looking for is vPC, and in 5.0 there is the config-sync feature to synchronize parts of the configuration between the two 5020.

Hi Tobin,
You will need to use/configure Virtual PortChannel(vPC) on the Nexus 5020s (instead of clustering).
It is similar to Cisco Catalyst 6500 Virtual Switching System (VSS). With regard to Cisco EtherChannel technology, the term “multichassis EtherChannel (MCEC)” refers to either technology interchangeably.
You may want to read below design guide for the big picture (if you want to see the available topologies with N5K and N2K please directly go to page 10)
And for the practical details, I believe below one would be better: (5K/2K topologies are in page 4)

I hope this answers your question.
Thanks,
