Arista is good but depends on the application. They have some of the most Jr code but they are coming along with features fast. Weve chosen them for several applications when compared to Brocade, Cisco, Extreme, And Blade. There pricing is on par with the others. ________________________________________ From: James Braunegg [james.braunegg@micron21.com] Sent: Thursday, January 26, 2012 7:27 PM To: Eddie Parra; Rodrick Brown Cc: nanog list Subject: RE: 10G switchrecommendaton Arista sounds interesting, although never knew of them !

We have used both Arista and the LG-Ericsson switches, both have done very well, and both have a great $/value proposition.

It's pretty good gear. The only problem I've had with it is the limitation of IGMP not working on mLAG VLANs.

hi George, IGMPv3 snooping has been supported since EOS 4.7. Its enabled by default in EOS 4.8.x. In terms of specifics, there is support for both IGMPv3 snooping & IGMPv3 querier.

Hi, Lincoln, *sigh* Ok, I see what happened. We just went through a software upgrade cycle on that unit and it got upgraded to the end of 4.6 instead of being upgraded to the latest release version of EOS. Looks like another upgrade needs to be done, probably to 4.8.3 Thanks.

I would not recommend EX4500 as an 10G aggregator switch, it has really small buffers.

I have experience with the Extreme's Alpine, Blackdiamond, x250, and x450 and i discovered that the command line is fairly different than Cisco, HP, or Dell. However, since they are a relatively small company with a small but strong customer base, their support is fairly good. I can't speak for 10G/40G implementations, but from my experiences, they support has a quick response time and they do quite a bit of lab replication to figure out the exact root cause. -Grant On Fri, Jan 27, 2012 at 2:32 AM, Erik Bais <ebais@a2b-internet.com> wrote:

Hi Fabien, I strongly have to disagree with you. We run a full bgp implementation on Extreme in our network and are very pleased with it and the support that we get from Extreme. One of our x480's we run has about 1.4 milj learned routes and another has around 200 bgp peers on the AMS-iX... So what is your point ? As an ex-Extreme employee making such strong statements, while you don't know the current status at customers, it may be best to ask who is using it and how, instead of acting like a grumpy ex-employee.

A place I worked around 2000-ish was an Extreme shop. My perception at the time was that they were probably the best switch in the world at layer 2. I used BGP on the 1i and 5i products. The problem we had with them was when I asked when they were going to support multiple path BGP (as in the maximum-paths command for Cisco / Brocade). They told me at the time that they had no plans to support that option, it wasn't on the road map, and frankly, BGP was not a priority for them as they were concentrating on layer2 metro and data center features at the time. That meeting resulted in a call to Foundry and the eventual purchase of several BigIron switches. As the application was just plain IP routing, they worked great. I haven't used Extreme since so can't attest to their BGP feature set but my gut feeling seems to be the same ... great gear at layer 2 but layer 3 seems to be a back burner priority for them. I would have no problem using their gear in an office or data center but would have to take a good long look at it for internet peering/transit. Arista is really good gear and I use them for 10G aggregation from top of rack switches in an application where pods of connectivity are scattered about in various leased cages in a commercial data center. The TOR switches link to the Aristas in an MLAG configuration which might look like an "end of row" configuration. Those uplink to the core in another bit of space in the data center to keep the number of cross-connects down. Performance has so far been perfect, not so much as a glitch from those units. I've also recently deployed them as TOR switches for a 10G cluster of machines and would have chosen TurboIrons if they would stack or had MCT features. The benefit of the TurboIron, if they will work for you, is the lifetime warranty. No annual support cost is a huge deal. Arista is also lagging in layer 3 and ipv6 features, or were the last time I looked at them at layer 3. That might have changed recently. They had only recently come out with OSPF support on their chassis units. One question I would have re: deep buffers. It wouldn't seem to me to make much difference if you are buffering on the TOR switch or buffering on the host. If flow control is giving you problems, maybe you just need more buffering on the host or maybe you should just let tcp back off a bit and mitigate the congestion using the protocol. More buffering can sometimes cause more performance problems than it solves but depends on the application. If I have a lot of "fan in" such as several front end hosts taking to a few back end hosts, I generally try to ease that congestion by giving that back end host considerably more BW. Such as GigE from the front end hosts and 2x10G to the back end servers. For example, an Intel X520-T2 card with 2x10G RJ-45 ports to a pair of Aristas in an MLAG configuration works pretty well provided you use the latest Intel driver for the cards.
I would like to point out that in my experience if you do a lot of coding/devops/automation work with SNMP extreme is a lot harder to work with than Cisco and some of their OIDs/MIBs produce unusual results.

Partially agree, Extreme has a "quit" good TCL implementation, and you can develop a lot of things around that. The system is able to reconfigure itself without external management console (SNMP) Fabien Le 27 janv. 2012 à 14:53, Drew Weaver a écrit :

We have a few Black Diamond 8800. There is big problem with microburst, congestion. There is only 4MB buffers per slot allocated dynamicly. Extreme support said: make LAG or buy another switch. Maybe this switch will be ok as access but not core or aggregaitng. regards Piotr
I would check out Extremes x670-48v they are very very affordable and have very low latency, We just bought a couple of them, And they do 40G module cards also. // Andreas -----Ursprungligt meddelande----- Från: Deric Kwok [mailto:deric.kwok2000@gmail.com] Skickat: den 26 januari 2012 21:21 Till: nanog list Ämne: 10G switchrecommendaton Hi all I would like to have 10G switchrecommendaton Ipref software can test around 9.2G but we can have congestion over 6G in single port!
