Yes .. and on the Juniper topic…
Just like Cisco or anyone else, you need to understand what it is that you are buying ….. the SCB example is something that should be identified during the purchasing to make sure you know that you are going to have a limitation or you are not. This would typically come up when you have older hardware combined with newer cards (but not always of course) Re: 4X10G MIC card, totally depends on the underlying MPC card but I’ve never seen a 4X10G card have degraded performance (granted firewall ACL’s have pretty much zero impact in JunOS and don’t use cgnat) Not defending Juniper here despite really liking their gear… the same situation happens in Cisco too … From: Af [mailto:[email protected]] On Behalf Of Josh Reynolds Sent: Friday, January 15, 2016 9:53 AM To: [email protected] Subject: Re: [AFMUG] Weird Problem with download That's not quite true. For example, on Juniper with a standard switching control board, a 16x10Gbps line card has a 4:1 oversub ratio. That interface line card retails for something around $160,000 MSRP. With the replacement of the standard SCB for an enhanced on, you can get full line rate on all ports. On an MX240 you might have a 4x10Gbps card, but with firewall acl and cgnat enabled you might be limited to 8-9Gbps total throughput through it. So to say "it just works" on the higher end of vendors and products is baloney. The difference with the Junipers and Ciscos and Brocades of the world is that they often have a higher tier of products for those entities that can afford it that will support their needs. Also their support is more highly trained (and there's more of them), and companies will fix your shit pretty quick when you buy a few hundred million worth of their products.

Those routers are made to support a Full routed 10Gbps/40Gbps/100Gbps of throughput per port. With Mikrotik it is a MAYBE it will if I don't do this or do that.. Obviously there are many models out there, but if you look at the true carrier grade router lines, it is a full routed port. I think each one has its place. Just my opinion..

Cisco, Juniper, AlcaLu, etc. are all just as likely to ignore problems and create bugs as Mikrotik, Ubiquiti, etc. When sitting at a table at about 1 AM one night with a head engineer with one international operator and one national operator I said something to the effect of, "I've just largely been listening to you guys comparing notes on different products and issues you've had. I use Mikrotik routers in my network and people often say they are junk and that Cisco, Juniper, etc. are the way to go. Those vendors are exactly who you guys use and yet here you are with the same type of complaints as we have with our vendors." The one at the international vendor chimed in, "and we pay 10x more for that right." Don't lose sight of that. For example, Cisco is known for having Ethernet chipset incompatibility issues.... which is exactly what this sub-topic has been about. To think otherwise is simply blind arrogance. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL> Midwest Internet Exchange http://www.midwest-ix.com <https://www.facebook.com/mdwestix> <https://www.linkedin.com/company/midwest-internet-exchange> <https://twitter.com/mdwestix> _____ From: "Eric Kuhnke" <[email protected] <mailto:[email protected]> > To: [email protected] <mailto:[email protected]> Sent: Thursday, January 14, 2016 10:49:12 PM Subject: Re: [AFMUG] Weird Problem with download This is sort of an illustration of why I am still very wary of Mikrotik for routers. There's a myriad of Cisco routers available with 12 to 20 SFP-based GbE interfacess (used/refurb) that are just as capable, if somewhat bigger and hotter, that run very stable versions of IOS. It's totally unacceptable for Cisco to break basic functionality for $HUGE_ISP and $HUGE_ENTERPRISE_CUSTOMER , which are usually using the same IOS trains I use for service provider functions. Mikrotik OS software support is pretty much "hey go over to this forum and hope somebody answers your question", if something is broken you are just supposed to wait for a new version release in a month or two. If something is fundamentally broken in a version of IOS used by a mature (6+ year old) Cisco platform it's almost certain that somebody much bigger and more important than yourself has already run into the issue, escalated it with Cisco, and a new build fixing the bug is available. If the space and power are available I would much rather have a 6503E with dual supervisor than a CCR....
