All,
What are the recommendations of Cisco regarding an Etherchannel between one Twinax 10GE interface and one 10GE SFP+ SR interface ? One uplink switch is very close and can be reached via Twinax, the other one not.
Is it possible to configure ? The Nexus specifications mention a link latency difference between the two types (0.25 µsec for copper, versus 0.1 µsec for fiber), so it doesn't seem to be a good idea to put them in an Etherchannel (although etherchannel load balancing is not packet based)
