You must be reading stacking information regarding a different model, as the ICX6610 has 4 stacking ports, not 2, and they definitely don't talk about using them for data - in fact it explicitly states they *can't* be used as data ports ever (thankfully this *feature* was snuck in in 8010 if I recall).Haha. I would never doubt you!
I want to understand how the def'n works and
The documentation states that
stack-port"selects only one of the two stacking ports as a stacking port, which allows you to use the other port as a data port." So I thought
stack-trunk 1/2/1 to 1/2/2means the stack consists of the 40G and breakout 40G port and
stack-port 1/2/1means use the 40G as the stacking port. Then on stack unit 2, if I want to use the breakout 40G, I would reference 2/2/2 using
stack-port. Basically connect between stack unit 1, port XL1 (1/2/1) and stack unit 2, port XL2-5 (1/2/2).
I feel it would really help if you could clarify on how cables are connected between stack units 1 and 2 based on the configuration you gave.
The top two ports on each switch are connected to each other for a redundant stacking connection in my setup. One 40gbE port, one breakout port. this leaves one free 40gbe port and one free breakout port per switch for me:
