Equipment Supporting 2.5gbps and 5gbps
I've a couple 10 port Cisco switches that support 2.5 and 5gbps over cat5e, just wondering if there are any other vendors out there with offerings that support these newer ethernet speeds. Supporting cat5e for these multi-gig speeds is a real boon in many circumstances given the wide popularity of it in many buildings. Does anyone have any experience with or knowledge of other products, switches in particular, supporting 2.5 and 5 gbps? Thanks.
It is really early days for this spec. I know there are a few SKUs are Cisco 3850 that have multi-gig support, but I don't know of anything else yet. -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Justin Krejci Sent: Wednesday, January 27, 2016 12:49 PM To: nanog@nanog.org Subject: Equipment Supporting 2.5gbps and 5gbps I've a couple 10 port Cisco switches that support 2.5 and 5gbps over cat5e, just wondering if there are any other vendors out there with offerings that support these newer ethernet speeds.

well, until the standard is ratified, these Multi-Gig offerings are quite proprietary.. there are 2 competing camps....hopefully they will be compatible and not end up like beta/vhs once the dust settles camp 1 - http://www.nbaset.org/ camp 2 - http://www.mgbasetalliance.org/ look at those vendors..... I think they hope by avoiding IEEE int he early stages and taping silicon they'll get the job done quicker - the drive mainly being faster wireless APs and cheaper data centre interconnects... alan

Hi,
Fortunately the two groups came together in the IEEE, and there are no competing standards.
right! so why do both keep updating their own marketing and web pages each month? ;-) thanks for the info though - our future world isnt messed up for multigig
- Optional Energy Efficient Ethernet (EEE) support
*optional* - in our current energy efficiency/green aligned world this should be mandatory
- Standard expected in September 2016
okay.. so buying now is like buying pre-N 802.11 kit - it should work with final standard but theres no cast-iron guarantee....new silicon might be required ? thanks for the info though! :) alan
Will we also get 2.5 Gbps fiber optics? SFP modules should support it? Regards Baldur Den 27. jan. 2016 23.00 skrev "Greg Hankins" <ghankins@mindspring.com>:

The 2.5/5G standards were born *entirely* on the rationale that someone wanted to get more out of the existing Cat5/Cat5e installed in buildings, so yes, you should go to 10G if you're on fibre. :) -- Tom
The goals of these BASE-T projects are specifically to extend the life of the large installed base of Cat 5e/6 cabling with higher speeds. I wouldn't expect there to be a fiber interface, because we already have much higher speeds that are supported on MMF/SMF at better costs (ie if you had a fiber cable, would you really want to run 2.5 GE when 10 GE is so affordable now).

The standard 24 or 48 port SFP+ switch is 10 times the price of the equivalent switch with 24 or 48 port SFP. The same is true for the optics. 2.5 and 4 Gbit/s SFP modules are available and cheap. It is just that ethernet ports will not take advantage of the extra speed. So it is only useful on fibrechannel ports. It would be an improvement if we can get 2.5 or 4 Gbit/s ethernet on SFP instead of paying for an all SFP+ switch.

You're buying your switches and optics in the wrong places. An SFP+ 10K w/ DOM is running me a little under $34. An SFP+ port runs me slightly over $102. (Juniper) On Thu, Jan 28, 2016 at 9:52 AM, Baldur Norddahl <baldur.norddahl@gmail.com> wrote:

I'd love to know what model Juniper you are getting for $102 per 10GbE port and where you are getting it. The lowest-end 10GbE switch is the EX4600, which lists at more like $850 per port. You can get higher-end ones with much larger port counts and get the cost/port down to about half that, but I can't imagine what you could be talking about for $102/port. I would kill for a 24-port 10GbE Juniper switch for ~$2,500. You can't even get a 24-port 1GbE for that. thanks, -Randy ----- On Jan 28, 2016, at 11:08 AM, Josh Reynolds josh@kyneticwifi.com wrote:

Dear Mr. Carpenter, Juniper is expensive. If you buy a new 48 x 10GbE/SFP+ fiberswitch from an H3C based vendor like Huawei, you get the whole unit for $10,000. All you need in addition to that are the lasers and these will set you back a hundred bucks per port in case you select 1310nm SFP+ modules (SMF 80km duplex), rendering a total price of less than $300 per interface, Best regards, Jonas Bjork ISP Senior Network Engineer

EX4200s are abundant for much less in Ebay (for the 24port 1g requirement). In the 10G space though, indeed, Juniper is expensive. On 1/30/2016 05:03 PM, Jonas Bjork wrote:

a single asic trident+ switch with 56 10Gb/s ports is in the neighborhood of 5k, less in volume... trident 2 is more. lopping ports off doesn't make the asic any cheaper.

Josh, Which Juniper switch are you referring to that is $102 per 10G port? On Thu, Jan 28, 2016 at 10:08 AM, Josh Reynolds <josh@kyneticwifi.com> wrote:
You're buying your switches and optics in the wrong places.
An SFP+ 10K w/ DOM is running me a little under $34. An SFP+ port runs me slightly over $102. (Juniper)

2.5 and 4 Gbit/s SFP modules are available and cheap. It is just that ethernet ports will not take advantage of the extra speed. So it is only useful on fibrechannel ports.
It would be an improvement if we can get 2.5 or 4 Gbit/s ethernet on SFP instead of paying for an all SFP+ switch.

The goals of these BASE-T projects are specifically to extend the life of the large installed base of Cat 5e/6 cabling with higher speeds. I wouldn't expect there to be a fiber interface, because we already have much higher speeds that are supported on MMF/SMF at better costs (ie if you had a fiber cable, would you really want to run 2.5 GE when 10 GE is so affordable now). Anything is possible though, if there is enough demand and a market then someone will make it.

Will we also get 2.5 Gbps fiber optics? SFP modules should support it?

Fortunately the two groups came together in the IEEE, and there are no competing standards.
IEEE P802.3bz 2.5/5GBASE-T Task Force stared in March 2015: - 2.5GBASE-T: 4 x 625 Mb/s over 100 m Cat 5e (Class D) or Cat 6 (Class E) unshielded twisted-pair copper cabling - 5GBASE-T: 4 x 1.250 Gb/s over 100 m Cat 5e (Class D) or Cat 6 (Class E) unshielded twisted-pair copper cabling - MultiGBASE-T auto-negotiation between 2.5GBASE-T, 5GBASE-T, 10GBASE-T, 25GBASE-T, 40GBASE-T - Automatic MDI/MDI-X configuration - PoE support including IEEE 802.3bt amendment (power over 4 pairs) - Optional Energy Efficient Ethernet (EEE) support - Standard expected in September 2016 - Interfaces expected on the market in 2016 - Task Force web page http://www.ieee802.org/3/bz/
You might have seen my Ethernet speeds presentation... the most recent one is here: http://ix.br/pttforum/9/slides/ixbr9-ethernet.pdf (December 2015)
It's slightly out of date as the IEEE Interim was just last week.

I've a couple 10 port Cisco switches that support 2.5 and 5gbps over cat5e, just wondering if there are any other vendors out there with offerings that support these newer ethernet speeds. Supporting cat5e for
Hi, these multi-gig speeds is a real boon in many circumstances given the wide popularity of it in many buildings.
Does anyone have any experience with or knowledge of other products,
switches in particular, supporting 2.5 and 5 gbps?
well, until the standard is ratified, these Multi-Gig offerings are quite proprietary..
there are 2 competing camps....hopefully they will be compatible and not end up like beta/vhs once the dust settles
camp 1 - http://www.nbaset.org/
camp 2 - http://www.mgbasetalliance.org/
look at those vendors..... I think they hope by avoiding IEEE int he early stages and taping silicon they'll get the job done quicker - the drive mainly being faster wireless APs and cheaper data centre interconnects...

The issue that causes the need for 2.5 and 4Gbps is older cable (cat5) that can't do anything faster, not the switches. You still need to replace the switches to use the faster speeds. This isn't the same issue with fibre, which can already support 10Gbps+. So it's the same difference. Upgrade switch on copper to go from 1 to 2.5/4 Gbps; upgrade switch on fibre to go from 1 to 10Gbps. The only possibility is if you got a 2.5/4Gbps SFP that would work in a current generation switch. I very much doubt that's going to work (but happy to be proven wrong by those in the know). In my experience 10Gbps switches now cost about the same as 1Gbps switches did a few years ago, so it's only the optics that are pricey. Unless you get them from one of the many cheap suppliers around, in which case there's essentially no difference in cost.
