On the CLI, start by looking at "net int show -role intercluster" on each cluster.

Make sure the LIFs for interclusters are on the interfaces you are expecting.

Next, run "cluster peer show -instance" from each cluster.

-> look at the local and remote interfaces. These should only be intercluster interfaces (LIFs)

SnapMirror traffic should only flow to/from those interfaces listed.

This is exactly what I did. What this approach doesn't guarantee is to always stick to 10Gb LIFs SM traffic, therefore there is my initial question.

Simply choose your 10 gb interface for your ICL. You could also put your ICL on a vlan off that 10gb link.
