Here i want to explain, how to create a double-sided vpc in an enterprise environment.
A customer of us want to redeploy his ESX Server connection from active-passive to active-active.
In the past the ESX Server were single-sided connected to one of the N5k devices with two 10 Gbit links.
The ESX Server were bundled in a port-channel on both sides. (N5k <-> ESX)
