Yes, it was staring me in the face this morning in the show chassis pic output. I just missed it.

I'm so accustomed to our EX4300's being the fully SFP+ models.

Nope, turns out this particular EX4300 IS 32X SFP 4X SFP+ now that I'm looking at it less sleep deprived

Valid, and I'm deleting my original reply to avoid any possible impropriety.

But EX4300 and EX4400 are both currently sold midrange switches, even the used/grey market is still pretty pricy for them. If you're friends with any partners, that might be the best bet?

Best we can get is an EX4000. 😂

Yessir... another Uni decided to drop *ALL* of their EX4300's around ~18months in. +800 40G capable switches at ~$1100pc, around that time QFX prices were bottoming out.

160Gbps of redundant BW to each building core, and the savings afforded us a new MX240
