We have IO Module 0 and 1 in both SPA and SPB are cabled.

We have been trying to create Link aggregates but a bit confused on ports selection.

Here are my questions.

1- is selecting identical ports from identical IO Modules from both SPs correct?  What is the best ports selection to create a bundle? I asked this because, when I select a port, the identical port from the identical port in the other SP will be automatically selected as a pair. So, if I select ports from SPA IO Module 0, identical ports from SPB will be paired automatically.

2-How many Link aggregates can we create in such a fully populated ports count?
