Seems pretty damn cheap to me (have not following Arista prices but from what I had seen - much higher).
6 available, so possibly takes a lower offer.

No idea if they have an OS, need one, need licenses for OS or ports, so do your homework before getting them :)

There are rear to front version for even less (Cheapest I have seen was 1400$ or BO) on ebay.

Does anybody know if these support the 64bit EOS firmware?

Looks like there are a bunch of listings at similar price range just now...

He reduced it by over $250, it's in my watch list but I bought from a Canadian seller in the end. The import charges are crazy.

I have the F model, fantastic switch.

Hate to hijack this, but has anyone found a good set of rails to use with the switch? It seems like Arista outer rails are easy to find but inner rails are much less common.

I managed to pick up this switch for around $1200. I think if I waited / made offers on more I could have found one for a bit cheaper, but it seems like a good price.

I'm happy with it so far, but still in the process of setting it up. With fan speed set to 30% it's quieter than the ex4300-48p it'll ~displace (*), and temps seem to be staying safe. It's also happily running with two kingston 8GB ddr3 ECC udimms, bumping the memory from 8GB to 16GB. It has an m.2 slot that I'm not putting to any use yet, but I'll throw one in before I rack it just in case I get curious what it can do.

It'll be my new homelab(/home) core switch - so far I've been trial-and-error'ing my way to find the right permutations of QSFP->SFP+ adapters and xvcrs that it'll allow me to coerce to different speeds to interconnect with 1G devices (a netgear poe switch + my srx300), 10G switches (an ex2300c), a 40G switch (ex4300), and various devices in the rack via DACs and breakout cables. So far it looks like the key is to just get a transceiver that's the right speed to start with - e.g. it doesn't appear to let you force a 10G transceiver to negotiate 1G.

And no, the irony of using 1G optics in a 100G switchport is not lost on me, but with breakout cables and 32 ports to go around this should work nicely with only about 50% of the ports in use for now. :)

@liampatterson I'm assuming you've found this by now, but I found a kit including the inner rails on ebay - seems there are more than a handful available.


(*) The ex4300-48p was a fine switch, but the poe version is too loud for my environment. It gave me a taste for 40G on a few machines, but ultimately didn't provide enough in the way of 10G interfaces. Now that I've moved all my POE devices to a less fancy netgear poe switch, I'm swapping in a non-poe ex4300-48t for 1G connectivity, which will cut down on noise/heat/power demand. The 7060cx is also replacing another (unexpectedly hot & loud) netgear 10G switch that I had put in to augment the 4300's 4x SFP+ ports and inability to use breakout cables.

I have this switch, SRX 300 and ICX 7250 POE.

This switch has 2 sfp+ ports, not sure it supports 1Gb, I use them to connect to 7250, and 7250 connects to srx300. I have a netgear 10G-T switch too.

What I found: so long as you use an SFP (1G) transceiver, it'll do fine. That applies to the SFP+ ports, and to the qsfp28 ports w/ a qsfp->sfp+ adapter. I haven't figured out a way to make itallow a 10G transceiver to negotiate 1G w/ a 1G peer.

That's because unless it's a (fiber) dual-rate SFP+ transceiver (FTLX8574D3BCV for example), it will only support the rated speed.

I've tried 10GBaseT transceivers that will negotiate 1G on other switches (e.g. cheap amazon 10gtek ones), and even they won't do it on the Arista.

The ASIC needs to support 1Gb, if not, it won't work.
ie. 7060CX doesn't support 25Gb, 7060CX2 supports it.

ah interesting. I don't have any 25Gb transceivers. I did find that the 1G transceivers I have work fine on it though.
