Now that I think of it, I did try this on the previous N1 code and I had the
same issues, you will have to be on the latest code.
In Nexus OS, you have a Kickstart and a system image they should both be of
the same version number. What you may be seeing is older images in the flash.
Run:
Show version | i .bin
Look up enhanced vPC. Here is what the document says.
Supported and Unsupported Topologies
Enhanced vPC supports the following topologies:
A single homed server connected to a single FEX
A dual homed server connected by a port channel to a single FEX
A dual homed server connected by a port channel to a pair of FEXs This
topology allows connection to any two FEXs that are connected to the same pair
of switches in a vPC domain. Static port channel and LACP-based port channel
are supported.
A dual homed server connected by FCoE and port channel to a pair of FEXs
A dual homed server connected by active/standby NIC teaming to a pair of FEXs
Enhanced vPC does not support the following topologies:
A dual homed server connected to a pair of FEXs that connect to a single
switch Although this topology becomes a functioning system when one switch has
failed, it is not recommended in normal operation.
A multi-homed server connected by a port channel to more than two FEXs This
topology results in increased complexity with little benefit
