Snagged an ICX6610 last year due to the popular thread here and my passing familiarity with them at a previous job. I'm using all but 1 of my 10g SFP+ ports up front, so when I bought another pair of ESXi nodes I wanted to use one of the QSFP+ breakout ports on the rear, but I'm running into some oddities. I'm using 1/2/6 as a 40g port to TrueNAS with no issues and had used 1/2/1 previously without trouble.
I've got 2 Cisco QSFP+ to SFP+ breakout cables, I believe they're passive but I'm not 100% sure on the model number, but can probably dig it up if that's helpful.
When I plug into the top QSFP+ it'll link up port 1/2/5 but not 1/2/2 - 1/2/4, only port 5. When I plug into the bottom QSFP+ port none of the ports 1/2/7 to 1/2/10 light up. They did briefly earlier today for a little bit but stopped seemingly after I added them to a VLAN, but I couldn't get them back up even after reverting the changes. I swapped between the 2 breakout cables and the behavior was the same. Also tried plugging the SFP+ ports 1-3 into known good hosts and they didn't link, but they work fine when connected to the front SFP+ ports.
I'm curious if I need an active breakout cable, or if there's something else I'm missing.
Here's snippets of my running config for the pertinent ports:
It looks like it's being detected in show media:
Thanks in advance for any insight.
