Hello Lori-77

That’s clear. The fastest port offers 2.5 Gbit/s. But these are not achieved in the Up. The synchronicity is therefore not given. However, this was fine in summer 2020.

But I have a question about Zyxel.

The IB3 uses XGS-PON. It seems to me that I once read that the signal is encrypted by Swisscom, so decrypting it on a device other than the IB3 would not be possible.

Have you already got a Zyxel device running on 10Gbit from Swisscom (or another product)? If so, can you tell us a little more about it (hardware used, settings, etc.)? I would be very interested in that.

Thank you in advance

Best regards

take a look here

Hello Jüre

Oh cool. I’ve overlooked it so far. Thank you very much.

I’ll read up on it.

Wish you a nice evening.

@roscho @SchnD

This morning, Tuesday, February 9, 2021, I had a lengthy conversation with Swisscom Support.

Checking the line gave the expected result: no problems.

I explained the situation (IB3 reports up/down symmetrically), cnLab measurement (carried out correctly, ie box to measuring point, one cable, no switches) shows down 2.4, up 03 (up to 0.9) when using the UB3.

Explanation that traffic is not guaranteed (up to 10G) and so the line works for Swisscom and the contract is adhered to.

Still: I’m getting an IB3 in the coming days with which I’ll do the same measurements (cn Lab, 20 days, 2.5G socket to 10G socket communicating with the MacPro using Thunderbolt 3).

I’ll keep you updated.

PS If the IB3 delivers the same result again, Swisscom will send a technician to the site.

Conclusion: Very professional call, I felt taken seriously as a customer and the investigation was started.

I’ll get back to you when the box has taken your 20 measurements for three days. If the result is the same, I would be grateful to the community for sending me your information. Or, if the technician’s visit has been unsuccessful, you can also contact Swisscom.

Of course I hope that the IB3 has a problem. When I turn on traffic shaping for WLAN, the screen turns into a flashing disco animation.

ATTENTION: As already said: The technical miracle is at work here, no complaints about lack of performance. I’m more aware of the privilege of having fiber in the back mountain area.

Hello everyone

I just realized that I forgot to mention an important detail:

Speed ​​test of the box, which can be found under Applications, shows symmetrical operation:

Internet box 3DOWNLOAD7959.76Mbit/sUPLOAD8103.66Mbit/sPING 4.73 m

But in expert mode under Diagnostics /Internet Box 3/internet the traffic is reported correctly:

There’s a dog buried somewhere…

I put everything on PDF.

Which firmware on the IB3 are you testing with? The field should currently still be 11.01.30 and some of the IB3s have already been brought to 11.03.36. But this is probably not final yet, there is probably still an adjustment in the DSL area, which is not relevant here.

Hi Smallpot,

Thanks for sharing and interesting project what you are trying in the other thread. Maybe I’ll try to get the Swisscom XGS-PON module to work in my SFP+ card under Linux soon. It would be nice to be able to look at the topics of PON and routing separately…

I made interesting observations on the topic of routing and Ib3 at the WE using iperf3. The transfer rate on the 1GB LAN ports 3 and 4 was massively lower than on ports 1 and 2 and on the 2.5G port.

I’m really looking forward to your exchange IB3…

Hello everyone

Firmware in the 3 is: 11.01.30/11.01.40/01598

Thanks

Smallpot

@roscho that won’t work with a Linux PC. With XGS-PON you need more than the SFP module. The part that enables communication with the network is part of the router HW/SW.

I think:

Presumably “the dog is buried” there.

Good afternoon Jüre

Thanks for the suggestion. Unfortunately, Thunderbolt 3 may not be the problem.

I tested it like this:

IB3 - Cat6a - OWC Pro Dock - with Thunderbolt 3 cable Apple (40) and MacPro

IB3 - Cat6a - Mac Mini 2018 with integrated 10G card

Both setups go via a switch to a Synology box with Inter 10G ports and achieve full throughput.

Thank you for every suggestion.

Best regards

Hello everyone

For the sake of completeness, here is the result of the Speedtest app on my MacMini with 10G card

Ping 3ms

Jitter 0.097

Loss 0

Down 2353 Mbps

Up to 402 Mbps

Test server: Wingo Lausanne

@Herby Does the CNLab speed test work without any problems for you?

YES. In any case, what can come out of the IB3 via cable at the back…

Edit: Sorry my mistake cnLap:

Edit2: The speed test of the IB3 leaves something to be desired…

@Smallpot:

_What does your “optical signal” look like when you click on “Internet connection” on the “start page” of the IB?~

Then I also think it’s more of a local problem. Have you ever tried a different cable?

Your setup is like? From the IB3 to a 10 GBit/s switch (which one?) to the devices? If so, if you attach a MAC directly to the IB3, do you have the same results?

Hello everyone

Yes, I also changed the cables (several Cat6a in different lengths and two Thunderbolt 3 cables from Apple).

In addition, the results are the same whether I use IB3-Dock-Thunderbolt MacPro or IB3-Cat6a-MacMini 2018 with integrated 10G Ethernet. Whatever I have tested and replaced, the result is always the same.

Nevertheless: I will document it again tomorrow so that I can rule out an internal error on my part.

With many greetings from the mountains from smallpot

Good morning everyone

I also think it has nothing to do with Thunderbolt. My measurements were made using a Mac mini with a 10 Gbit NIC. A comparison measurement with a Windows device and also 10 Gbit NIC shows the same pattern. The NIC card on the Windows computer is a low-budget device and the measurement in the upload is even worse than on the Mac.

@Smallpot:

Can you install the latest beta firmware and run the test again. Would be interesting to know if the problem is also reproducible.

And a second question:

Does the asymmetry also occur on the 1G port?

Thanks,

MichelB

@MichelB @Smallpot already has 11.03.36. No difference.
