Netgate 6100 and ONT Link Negotiation
-
@robbiett Yes, the yellow crash banner is the key. When you open it, it will display the crashdump files that you can also save as a archive by clicking download crashdump.xx.x.
My first info.0 contained the MCA error in my case, but the second crash did not - it was a unrecoverable machine check option instead. But If you search through the crashdump it will show lines like:
Unrecoverable machine check exception
and
MCA: Bank 5, Status 0xba00000028000402
MCA: Bank 5, Status 0xba00000028000402

cpuid = 2If you save the crashdump the upper one will be in panic.txt, the lover is part of msgbuf.txt
Very interested to hear if you are seeing this as a part of your crashes when they happen.

@robbiett But since yours is a page fault - I doubt you are seeing the same issue as me.
Perhaps it is just my hardware that coincidentally decided to die off the same week I installed 23.01

We'd need to see the actual crash report not just the info file to know more there. It should be linked in the same place. Obviously it shouldn't happen though.
One thing to be aware of there is that the igc NICs can only link using auto-negotiation. They cannot use a fixed speed/duplex. The available settings there restrict the link speeds to allows in the negotiation so can limit it to a single speed but it still has to negotiate it. So if it fails to negotiate 2.5G without any restrictions it will probably still fail when set to 2.5G only.
Have you confirmed the ONT actually can link at 2.5G with something else? I think this is the first time we are seeing 2.5G Openreach supplied device.

@stephenw10 Thanks Steve - that is all I got at the time, unless it is hiding somewhere I can access post-event.
Yes, the 2.5 GbE ONTs are very new here. The first few went out on a trial in Oct & Nov last year and they only started shipping to some customers in late January. I happened to be one of the first.
When the ONT arrived I did bung it directly into a de-populated switch (either a UniFi US-24 Pro or an XG-24) just to confirm that it linked at 2.5 GbE. I was minded to do that again, just to re-validate the cable run. Not had chance yet but thinking afresh I do have a Netgear NBase-T switch hiding somewhere, so I should try that...
I also tried power-cycling the ONT to see if a cold-boot would help it achieve a 2.5 GbE link to the 6100 on autoselect.
I didn't appreciate the all-or-nothing 'autoselect' feature for the igc. On the ix ports I had to fix 10 GbE at both ends in order for my switch to establish a link. The 'autoselect' refused to work, with the port lights showing the attempts and brief links and the UniFi switch alternating between '10 GbE' or 'SFP+ Port Down'. That said, the UniFi SFP+ cages can be fickle in their own right.
I will look through the 'network hoarder's' pile of old network kit and find the 2.5 GbE capable Netgear switch to answer your question above.

Can I assume that, like other supplied ADVA devices, there is no customer access to it's management interface?
If you have switches available for testing I would try putting one between the 6100 and the ONT. That would confirm it's a link negotiation issue.
Unfortunately I imagine it will be a while until those units appear on ebay at a price I can justify for testing.

- Tried the Netgear switch, fresh cable and connected to the ONT:
1GbE - Tried ONT boot with Netgear switch connected:
1GbE
So I went back to my original working 2.5GbE link on my main 2.5GbE UniFi Switch and that result has changed, with only a 1GbE link established.
I can only presume that a subsequent ONT firmware update has removed the 2.5GbE capability, at least for now. Bummer. The joys of Openreach and their strapped-down approach to everything.

Ah, OK. Yeah sucks that there's no access. Yet.
Edit: Checked my usual source for this sort of thing; you're already there.

Ahhh yes, the halcyon days of 2 months ago, when the ONT did link at 2.5GbE. Times change, scream if you want to go faster!

Mmm, I can only dream of the day Openreach finally decide to put fibre where I am. Despite the fact I'm only ~300m from the exchange and was in one of the original FTTC trial areas. Grrr.
Stuck at the slow end of g.fast for now. -
@stephenw10 - I hear you. Having enjoyed rapid roll-outs when I lived in the south I was rather shocked to see the state of things when I moved up here.
Having been on the rump of every Openreach infrastructure change (including the debacle of ECI G.fast) you could have knocked me down with a feather when they announced proper fibre plans for my area. Apparently we were on a list of 'arse-end areas we usually ignore'* and attracted additional funding under a lacklustre government scheme.
Small mercies.

They are doing Fidium fiber in our area. Their website states we can't use our own equipment even our own WiFi. But someone from the city did a post on Reddit it shows you can. I wonder if I got a SFP adaptors for my SG-2100 if I would not need the ONT modem and have the ability to authicate directly to the 2100 too? Or just use the ONT as the fiber converter to RJ45 cable and go that route. Who knows. I got a letter that they are discontinuing DSL soon for our area and to update now. I had a manager come to my house a couple times asking why I haven't upgraded yet as they installed the neighborhood main distribution connection on the power pole in my backyard a couple months ago. I showed him my PfSense snort logs and explained my past work world and the reason I have a firewall and all the issues in the past without one. He confirmed that yes I can use your own router it's not an issue to have the installer call him if he tells me he can't. So when they disconnect I will update you on my adventure with ONT or just using their modem without the Zytel box. I just like my DSL from Consolidated, it has worked perfectly for years. I am kind of waiting it out until I am forced to update.

My connection with fidium has been great ... 1g plan and they credit me $10/month for having my own router. 2.5g rj45 on the ont to my 6100.
