Curious if anyone's used the 7280 and wants to share their experience? I'm looking at it primarily for three reasons, MLAG (i.e. multi-chassis LACP), large ARP/MAC table (256k entries) and large IPv6 neighbor table (256k entries). For the table sizes we would like out of one pair of switches, we'd be into the Cisco 7000 series, but that's dramatically more expensive and we don't need much of anything else that it offers. Looked at Brocade too, but they don't have devices that can do the multi chassis LACP, has the huge table sizes and has a reasonable number of 10gig ports. It was possible to construct a workable solution using VDX's for switching and CER's for routing, but that's more complex than Arista's option if it's a usable option. Thanks, David
Have you looked at the brocade MLXe line? On Nov 24, 2015 12:05 PM, "David Hubbard" <dhubbard@dino.hostasaurus.com> wrote:

I love the MLXe as a platform. Especially for a campus style switch. Also Cisco really isn't expensive. Not for this type of application. A 7606-S can be purchased refurbished for like 90% off list price. The market is seriously glutted with them. Quoting Josh Reynolds <josh@kyneticwifi.com>:

Not sure the OP was talking about 7600s. They're mostly End-of-Life, and not in any way suited to the OP's requirements (MLAG missing, low density, nothing like Arista 7280) If the Cisco refurb route is available, N7K is probably obtainable through those channels. You'd be surprised what companies lease and then throw back for whatever reason. And in relation to Brocade: I'd feel very uncomfortable throwing any *new* money at MLXe, CER or CES. Strategy for those families seems to have fallen off of a cliff. -- Tom
Hi, Hardware is really nice. Backplane, buffers, just basically “pumping” bandwidth. It’s really good. However, mlag can show some bugs when having only 1 interface in an MLAG (only 1 side) they had issues with the ifindex numbering in software. There were OSPF configuration options missing, etc. In short, hardware is really nice, software needs more maturing. Nice for distribution but not for core.

These are being implemented in production on many a bank network...so yes, they are plenty good enough. You will obviously need to test them in a lab to make sure the features you need to implement don't have any bugs that need to be addressed first. Overall I've had good experiences with them though in a spine/leaf topology in major data centers. I've also been implementing Arista switches as core devices outside of the data center with some pretty great results, but you need to be careful to make sure the features you need are available on the platform you want to buy. As with Cisco (and any other vendor) there are some hardware limitations where some features will exist on one platform, but not another.
