switch 10G standalone TOR, core to DC
Hello, I looking some 10G switches, it should work as TOR or core in DC. It should have more than 40 port 10G in one unit, wirespeed L2 L3, with virtual routers and some other ip functions like some BGP, OSPF, policy routing, 1-2U, MLAG, g.8032 (ERPS) trill-like ? Other important features are big port buffers ( something similar to Juniper EX8200 - 512 MB per slot), defined counters accessible via snmp (like in junos), L3 statistics accessible via snmp Extreme 670 looks good but they have small port buffers. It can be also some small chassis with line cards but the cost per 10G ports is too big.. What vendor, model You prefer or suggest as a solution ? thanks for help best, Peter

the extreme x670, juniper ex4550, brocade ICX6550 and arista 7150 will most of this, and probably many others too. None of them will do trill. The Extreme X670 and Juniper EX4550 will both do VPLS, though. The X670 won't do BGP. You won't find a box of this form with large port buffers. There don't appear to be any of these boxes on the market at the moment, probably because none of the switch vendors want to bite the bottom out of their more lucrative chassis-based switches. This is a good market opening for a new vendor - there is no technical reason why this couldn't be done. Nick

this is incorrect: the ex4550 will do l2vpn/l3vpn but not vpls. The X480 does vpls, but not the X670.

I normally just lurk but I thought I would post to clear up the confusion. Full disclosure, I am an Extreme Networks TAC engineer. The x450 does not support any VPLS/H-VPLS/MPLS and is discontinued. It was replaced with the x460 which does support VPLS/H-VPLS/VPWS. The x480 and x670 both support VPLS/H-VPLS/VPWS. The x460, x480 and x670 all support BGP. However, only the x480 can hold the BGP full-view in hardware. So while you can run BGP on the x460 or x670 they are really only suitable for iBGP. All switches require a Core license to run BGP and an MPLS license to run VPLS/H-VPLS/VPWS. Andrew

Thanks for the clarification on this. The data sheet on the x670 doesn't actually mention vpls: www.extremenetworks.com/libraries/products/DSSumX670_1777.pdf ... just that there is an mpls feature set license, but with no details of what it contains. Normally vendors can't tell enough about useful features like this, so in the absence of mentioning it I had assumed incorrectly that it wasn't supported on this platform. Maybe you could get the documentation updated to include this information, because this is an important feature? Nick

Thanks for pointing that out. Documentation folks have been alerted. For a quick comparison of all switches I like the Comparison Guide the best. http://www.extremenetworks.com/libraries/products/MSComparisonChart_1636.pdf --Andrew
although everyone here seems to hold Cisco in contempt, the Nexux 5548 is a rock-solid switch - at least that has been my experience with it. On Tue, Jan 29, 2013 at 6:27 AM, Piotr <piotr.1234@interia.pl> wrote:

Peter, Network visibility wasn't mentioned as a requirement, but it is worth considering since the ToR switches are the best place monitor server network I/O, tunneled traffic (VxLAN, GRE etc), storage (iSCSI, FCoE, HDFS etc). The Nexus 5548 switch does not include monitoring (i.e. no NetFlow/sFlow). The Nexus 3048, along with all the other 10G ToR switches so far mentioned on this thread, supports sFlow and provides wire speed 10G/40G monitoring. The following article provides additional background: http://blog.sflow.com/2012/02/10-gigabit-ethernet.html Cheers, Peter On Tue, Jan 29, 2013 at 7:15 AM, Steven Fischer <sfischer1967@gmail.com> wrote:

Hi, I do suggest you go over EN offering with a fine tooth comb. We experienced a whole lot of issues with 6 x650: . from hardware licensing (start at shipping from the fab and not when the customers get them); . software licensing (have to license every box even the ones in the labs); . known eeprom defect limiting upgrade from XOS 12 to 15; . 1 vlan-translation causing all sort of head-aches with port-grouping (ether-channel); . EAPS packets being silently filtered out of VMAN's when you do not use the Core license; ( Undocumented and that is not acceptable when trying to transport customers owns EAPS traffic on their VLAN's ) . no VLAN flapping logging; Don't get me wrong, they are good campus switches... just not designed for "our" L2 Core purposes. And the Licensing is just an exercise in frustration. I can understand the business purpose, just not the way they go about doing it. As for L3 support, it is fine: . include IP tracking in VRRP with is a plus for us . Virtual Routers We don't need them for BGP and we do not have a MPLS network yet. As for the x670, maybe most of the hardware issue has been addressed, but I doubt the licensing and undocumented limitations is better. PS: We're using them (x650), and are planning to keep using/recommending EN products, but it did cost us a lot of man hours and un-planned crashes that could have been prevented with better documentation and support.
