Link Aggregation does not work with 10Gbps interfaces on certain models?

[simonorch]

I was informed today that certain models do not support link aggregation of their 10Gbps interfaces, specifically the 900D and 1000D, or perhaps it's better to say that it doesn't work.

Is this true?

If so, are there other models that don't support this, like the 600D?

In case anyone stumbles across this as I did, here is a link that shows the architecture of the NP6 on the 1000D. The links on the right show other models.
