RE: Design issues: Inter-connecting Nexus 5000 switches

Whether you are running VPC or not interconnects provide link redundancy,
protections from a single path failure. Yes spanning tree comes into play
at that point but isn't that what it is designed for?

Hi Mish,

I need to know more to help you with this design.

1- Do you have any N2K in your network? (Fab externder)
2- How does your hierarchical design look like? (i.e. fabric layers)
3- Any FCoE enabled servers/blades?

Hi,

I'm wondering if anyone could give me the pros and cons of
interconnecting
Nexus 5000 switches other than the reason to run vPC in between them.
I'm of
the opinion that access switches should never to interconnected due to
possible STP looping issues. In this case however, I'm not so sure in
the
case where vPC fails, will this cause some degree of exposure to STP
convergence issues?

Cheers!!
