We have a FAS8080 that is under third party support. We are adding new Cisco core switches to our environment and need to purchase new cables. Looks like Cisco only makes active twinax for the length we need.
Curious if a FAS8080 can use active or if it would need to be passive.

hwu.netapp.com would be the best place to check for compatiability.

ONTAP implements LACP in nonconfigurable active mode that works well with switches that are configured in either active or passive mode. ONTAP implements the long and short LACP timers (for use with nonconfigurable values 3 seconds and 90 seconds), as specified in IEEE 802.3 AD (802.1AX).

Thank you @pulsar pollen and @vital lantern

Anytime, it’s what we do 🙂

I think someone is confused here. OP talks about active twinax cables, while Nick talks about LACP. Those two things are totally unrelated (except that they both have to do with "networking" and share the word "active"), nobody notices and OP accepts the non-answer and leaves? If nobody else, then at least I am totally confused 🤨
to correctly answer OP's question, no, active twinax cables are not supported. They might work, or they might not (from my experience they don't work, link does not come up). They are definitely not supported. If you need to go above 5m you have to use SFPs and optical cables.
We see enough of that "search the KB for keywords and blindly copy-paste some text" from NetApp's 1st and 2nd level support already, no need to continue that practice here on discord 😦

I assumed he was referring to active/passive LACP in LAG's

ONTAP historically has never supported active (AOC) cables. Exceptions were for SAS connections longer than 5M
Recently though, I have seen support for 100g AOC but only on certain platforms.
With that said, I saw a customer plug a 7M AOC onto a Netapp and it would not link.
You are way better off using optical transceivers with om3/4 fibers.
Even if the aoc seems to work ONTAP don’t know goes to use it properly (the full drivers for the cables are not there) and you may have issues.
Work with your var and see about getting supported third party optics from a place like add-on networks. They have something like the x6589-r6-ao which ONTAP likes

We are looking to get 7m cables and it looks like Cisco only has those in active.
We can go with third party although we were concerned by not using Cisco cables that if something goes wrong with the switch, Cisco will not support the port due to them not being proprietary Cisco cable
