If I understand you, yes, we have that configuration:
e4a Cluster Cluster up 9000 auto/40000 healthy false
e4e Default - up 9000 auto/10000 healthy false
e4f Default - up 9000 auto/10000 healthy false
e4g Default - down 1500 auto/10 - false
e4h Default - down 1500 auto/10 - false
e4a is the 40GB connection back to Cluster Switches
e4e and e4f (two of the 40g to 10g split are ran to our network switches)
e4g and e4h are just hanging there on the other end. (Messy, but it is what it is)
If you are talking about the configuration on the other end (Where the 10g splitter connects into) You will need to create a ifgrp on the Netapp side, and a port-channel side to bond them all together.
