BTW, breakout cables are very common and widely used in deployment to connect existing 10G/25G NICs.

@jeff-yin Could you please help with this one?

[jeff-yin]

Please assign to @arun1355492 -- I don't seem to have the ability to do so.

Hello,

I attempted to add Breakout Support myself: b5d81ea.

I reviewed the changes from this PR: #20287 and made similar modifications for the S5232F-ON.

[johnathost]

The pull request (#21901) introduces this feature.

I’ve tested it on a demo S5232F-ON unit, and the results were successful.

@jeff-yin, could your team review the changes I’ve made and share your feedback—positive or negative—before merging the PR?

Thanks!
