Can i "bundle" two uplink ports into an Etherchannel and then statically pin the server ports to the "bundle" (portchannel) and not the individual links ?
Yes, you absolutely can uplink the FI with a port-channel to VSS or vPC.
See this for a visual of this design:
I think Mike Frase was referring to how the IOM (I/O Module) inside the blade enclosure uplinks to the FI -- and he is correct that port channel is not currently an option for those links.
p.s. Please rate if helpful
