I have a switch stack of 3750E-24PD-E that includes 9 Switches. They connect to two Nexus 7010's by 8 ports bundled together in an interface port-channel ten gig connections. I have already seen the vPC fail once on the Nexus side. I easily fixed it, but the stack was down till I did, in my business that is unacceptable. Can I set up a second vPC, between the stack an the Nexus 7010's and some how port cost it like I would a standard redundent wire connection.
I assume if I can, I would put the port cost on the port-channel interface.
