NZNOG-People, I have just finished migrating all of the mailing lists held at The University of Waikato from one server to another. I don't have any reason to believe that anything's gone wrong, but please bear with me for today if it turns out that something has. - Donald Neal -- Donald Neal | Q: How many Aucklanders does it take to change Systems Programmer/Analyst | a light bulb?

UFB 2M upload issues - DEI markings - Juniper
by Dave Mill 19 Nov '15

19 Nov '15

Hi all We have finally fixed our 2M upload issues on Chorus UFB accelerate plans. Skip to the end of this email if you just want an example fix. Along the way we established a couple of incorrect "facts". Some of which I shared with this list. These were: 1) DEI marked packets were being silently dropped on ingress from the Chorus handover 2) Junos 12.3 fixed this issue Recently I deemed that "fact" 1) was wrong and hence "fact" 2) was a bit irrelevant. Here's a crude diagram of our typical set-up: <Chorus handover> <-> [1] <MX80> [2] <-> MPLS/VPLS over Backhaul fibre <-> [3] <PMR MPLS MX> [4] <-> [5] <PMR BNG> Where the numbers in the square brackets are interfaces where I performed some traffic stats. I deemed that DEI=1 marked packets were still showing up at [1] and [3]. They were not showing up at interfaces [4] and [5]. This deemed my above "facts" incorrect. With Juniper CoS you classify on ingress and rewrite on egress. Once we deemed that DEI marked packets were not being dropped at [1] and instead were being dropped between [3] and [4] we can now rewrite these before interface [4]. As we need to rewrite on egress we'll do this at point [2]. In our test case interface [2] is actually xe-1/2/0.388 . And a simple fix for the issue is under the class-of-service section implement: interfaces { xe-1/2/0 { unit 388 { rewrite-rules { ieee-802.1ad { ieee-802.1ad-dei-rewrite; vlan-tag outer; } } } } } rewrite-rules { ieee-802.1ad ieee-802.1ad-dei-rewrite { forwarding-class best-effort { loss-priority low code-point 0000; loss-priority high code-point 0000; } } } The key is to use a ieee-802.1ad rewrite rule rather than a ieee-802.1 rule. The leftmost bit of the 4 bit code-point is the DEI bit. This is all assuming that all traffic is classified as best-effort at interface [1] - if that is not the case then re-write the DEI bit for your other queues as well. You only need to rewrite the outer vlan DEI bit. This is tested on Junos 12.3R8.7 on a MX80. Thanks to all involved in helping fix this - Steve K, Vance and Ivan especially. Cheers Dave

UFB Upload Issues
by Dave Mill 20 Aug '15

20 Aug '15

Hi all If any RSPs currently have any reports of 100/20 UFB Right Performing customers having only 2M upload could you contact me offlist? If you do contact me I'm really interested in where your BNG is and where your customers are with the issue. If any end users are on 100/20 with only 2M upload also feel free to contact me. I'm more interested in your location and your ISP in this case. Cheers Dave (representing Inspire Net in this post)

Chorus EUBA + IPV6
by Simon Allard 02 Aug '15

02 Aug '15

Since it seems to be ipv6 month here at NZNog I thought I would bring this up. Some of you have commented that Orcon is in trial mode for IPv6 and are probably wondering why we haven’t progressed. We have had IPV6 enabled for a while and have a good number of ipv6 customers online now. However we found an issue on the Chorus network which stopped us rolling it out further. (UFB ipv6 was another battle which requires beer!) What we found was some Chrous DSLAMS with certain card types would drop IPV6CP packets in one direction when doing the PPPoE->PPPoA conversation. It would seem that these cards don’t support Ipv6. Weirdly enough it would seem it is the newer card types used for Broadband IP. (citation needed). This in itself isn’t a major but we also found our NFV4 modem would reset its entire PPPoE stack if the IPV6CP conversation started but didn’t complete as expected, so customers would constantly be disconnected and cycle around. (The Genius modem works well with ipv6) The NFV4 issue aside (we are resolving with the Vendor). We approached the Chorus tech team and they helped identify the issue but that’s is where its hit a brick wall. The Chorus op team are not keen on fixing the issue nationwide as it involves new code versions, a massive amount of testing and a long rollout program. (I can understand where they are coming from). To summarise: IPV6 doesn’t work on Chorus EUBA on some line card types Only affect PPPoE->PPPoA translation PPPoE end to end is fine. Chorus say IPV6 not supported on EUBA Customer numbers effected are smallish. We will fix the NFV4 issue, but keen to rollout more IPV6 to all customers, not just the lucky ones on card types which work. Has any other ISP’s (the bigger ones especially) noticed this? As it will require some pressure to get some progress.

openwrt capable routers for NZ?
by Dave Taht 09 Mar '15

09 Mar '15

at the end of my talk someone asked me what routers I would recomend to try this stuff on here, and I sort of dodged the question. If you can come up with a list of routers available here (meet me later?), I can tell you what I know about each chipset. (I have evaluated dozens of these over the last year...) In general ath9k based gear is currently best (entirely open wifi driver), with nearly every manufacturer shipping stuff based on that. I see there is a lot of ubnt here, and most of their older products are well supported by openwrt. There is some good work beginning on the latest round of chipsets, but by and large the firmware for 802.11ac is closed.... And so on. I should also point out that there are plenty of other OSes available, and that I'm opposed to a monoculture of any hardware/software combination. See: https://gettys.wordpress.com/2014/10/06/bufferbloat-and-other-challenges/ for more details. -- Dave Täht thttp://www.bufferbloat.net/projects/bloat/wiki/Upcoming_Talks

Thanks NZNOG
by Terry Manderson 31 Jan '15

31 Jan '15

Hi NZNOGers, I'd just like to say thanks. Thanks for the hospitality extended to an Aussie. Thanks for a really nice 2 days of thought provoking and interesting speakers. Thanks to the current trustees for making it happen, and thanks to the sponsors for all the schwaag and subsiding the event (as they always do!). Mostly I'd like to give thanks to the exiting trustees Neil and Dean. Like previous trustees Joe and Andy they have given much of themselves, of their time, and their expertise to make the Internet a better place through NOG coordination. I know this first hand in my role with AusNOG. It's a tireless beast. Often without thanks. It chews up personal lives and makes employers look at you with raised eyebrows. People often comment "why bother", and question your sanity. But ultimately what you have done makes the Internet better, and each person who takes it on and makes such efforts to this amazing concoction of technology contributes to an entire world of "better". And it's with that sincere goal which you have both plainly embodied, that I offer you MY thanks and my appreciation for all you have done. You deserve more than just this email, more than the beer I will buy you when next we meet ... you deserve the recognition for those selfless efforts. Well done. Cheers Terry

Suggestions for router with 3G external antenna for remote site comms
by Darren Moss 31 Jan '15

31 Jan '15

Hi All, We have a bunch of regional sites (weather probes) that run some equipment, 2 PCs and are connected to the internet. At the moment it's dongle city which I would like to change over to something a little better :) I am looking for suggestions on a decent (business grade) router with 3G capability an external antenna connection. At each site, the equipment sits in a rack, inside a hut and signal strength is reasonable (3/5). My thinking is to deploy a basic Cisco router with a 3G WIC then an external antenna on the same mast where we collect weather data. Happy to hear suggestions and input. Many thanks Darren.

Operators and the IETF
by Brian E Carpenter 29 Jan '15

29 Jan '15

Following up on the lightning talk I just gave in Rotorua: The IETF is concerned that we're not getting enough operator input at the time it counts: when specifications are being developed, years before they come out in software or hardware. There's been an effort to investigate the reasons for this problem, prior to trying to fix it. Everybody involved in Internet operations is welcome - indeed needed - to contribute. Full length presentation: http://www.ietf.org/proceedings/91/slides/slides-91-opsawg-0.pdf IETF draft: https://tools.ietf.org/html/draft-opsawg-operators-ietf Mailing list (anyone can join): http://snozzages.com/cgi-bin/mailman/listinfo/synergy Internet Society page: https://www.internetsociety.org/deploy360/operators-and-the-ietf/ How to get started with the IETF without further ado: http://www.ietf.org/newcomers.html Regards Brian Carpenter
