Hello,

Could someone please advise on why breakout feature seem not to work:

Breakout is not supported on ports connected to the NS ASIC (ALE) .. I.E. the 40g ports on 9372, the 6 40g colored ports on 9332PQ etc.. There's a document here that explains the limitations , of which there are A LOT unfortunately:

Thank you f00z for providing this document.

I am perplexed that Cisco TAC obviously does not understand their own architecture; Cisco TAC recommend to upgrade this NX switch to RN 9.3.10 in order to gain the breakout functionality. I hope some of Cisco Engineers reading this post and charming in to this discussion. Thanks Netmart.
