connecting 3800 stack to Nexus 5K vPC

[RussellGibbons]

As the title says, I am connecting a stack of 3800 switches to a Nexus 5K pair using a virtual Port Channel. However, the second connection never comes up, and in the one case we've had where connection 1 goes down, the second connection didn't take over. Is anyone out there doing this successfully?

Thanks,

Russell

Apparently spacing is not kept when pasting. Let me know if any other show commands would help.
