Hello, I'm looking at setting up a set of 3524x's in a vPC domain. I've seen a lot of recommendations and they usually involve a pair of 10G links. From what I've read/understand, there shouldn't be a lot of traffic on these links during normal o...

The switches will only be Layer 2 for the ISP connections. The switches are there to terminate the fiber connection and to break out the single hand-off to the pair of Active/Passive firewalls and router. All the public IPs will be used at the Firew...
