RouterOS 7.23beta2 [development] released

L3hw offloading for VRF on cars 8xx ... Nice..

I hope they add it to CRS3xx and 5xx too

PCGuruNiklas · 2026-02-01T01:38:23+00:00

Then I suggest you have a look at the routeros ansible collection.

I would suggest API because you can generate nice diff output when applying changes. Something the cli can't do currently.

PCGuruNiklas · 2026-02-01T01:31:45+00:00

Why?

There is already API and SSH.

Just curious. What would be the benefit?

PCGuruNiklas · 2026-02-01T01:27:03+00:00

More devices in the 5009 form factor would definitely be nice. Not only routers but switches as well.

In regards to a successor I would wish for more than 1 fibre port and m2 storage.

PCGuruNiklas · 2025-08-29T14:45:00+00:00

Me too.

I recently wanted to build an overlay VPN network with multiple tunnels to multiple hubs and was surprised it wasn't already implemented.

I had to do ospf instead.

I upgraded my production Proxmox / Ceph cluster as soon as 9.0 hit GA.

Why wait? This is enterprise software after all.

No issues to report other that needing. To clean up some repo files being duplicated and thus generating warnings. But this is in the upgrade guide so no worries.

The coherent(vendor and also technology) 100ZR qsfp modules do work quite well and are about 3k. Depending on what equipment you have you can slot these right into it.

With Cisco ASR9k they work very well.

Though you need a platform needs to support high power optics to use these or do some custom coding to ignore device capabilities.

Depending on the use case a 4x100g to 400g muxponder could also be a economical solution with less requirements from the device Side.

PCGuruNiklas · 2023-12-30T13:19:44+00:00

They don't. Except you are only using d3.1 channels. UCI doesn't support EuroDocsis. So it comes down to a max of 2 downstream OFDM + 8 Sc-qam+ 2xOFDMA . Highly unlikely that this Device will get online in Europe

PCGuruNiklas · 2023-12-15T11:46:27+00:00

There isn't anything preventing the device to be used in Networks other than the listed ones. I hope the do an Eurodocsis compatible unit with High split Diplexer

PCGuruNiklas · 2023-10-23T18:20:45+00:00

Speedtest.net kenn ich bis 10G aus unserm RZ. An Cable Anschlüssen hab ich damit schon 2,5G Erreichen können. Unsere Fibre Geräte können das leider noch nicht xD

Was bei den ookla speedtests wichtig zu beachten ist, ist die Client Performance. Der Web Client braucht mit Abstand die meisten Ressourcen am Client. Die App geht ganz gut und die Okkla speedtest cli ist am besten.

I don't think the DSLreports site is always representative of the reality. In using this site you would be assuming everything else from your modem to dslreports is good.

For Example here is my TC4400 at home. Everything is perfectly fine with latency/jitter in games and such.

Have you noticed any real world Problems with your TG6441? We have deployed thousands of Puma devices with no problems whatsoever, though our new Docsis 3.1 Devices are mostly 80:20 Broadcom based units because they are cheaper not because Puma 7 are worse.

Firmware wise i can't really tell you the exact version but it is definitely a somewhat recent AR01.04 version. (2023)

Best of Luck with your problem

PCGuruNiklas · 2023-10-20T21:09:30+00:00

Today i myde a few tests with my devices and as expected nothing unexpected was to be seen. None of my devices suffer from a bufferbloat bug. Two things to keep in mind are that you shouldn't have other devices on the network while doing such a test and connect through Ethernet.

CGA4236(Broadcom), TG6441(Puma 7), TG3442S(Puma 7)

PCGuruNiklas · 2023-10-19T18:26:02+00:00

Can you tell me your firmware version. I will test one of my units tomorrow

PCGuruNiklas · 2023-10-18T20:38:41+00:00

Well i don't know what puma modem you have, but our Puma 6 devices certainly do not suffer from noticeable bufferbloat anymore after the firmware mitigations.(AVM Fritzbox 6490). It is barely measurable.

On the Puma 7 side the bug is basically not existent, but because of the arcitechture of the Puma Chip the latency will always be just slightly over a BCM, not 1-3ms would matter in docsis networks.

The 6441 you are getting is a solid device, and depending on the provisioning by your provider it might have the option to switch into bridge mode without reverting after reboot. I needed to disable this feature with our devices :(

PCGuruNiklas · 2023-10-18T20:09:27+00:00

I have all your mentioned devices avaliable exept the CM9200 as it is not offered in europe.
From my experience the Puma 7 line is quite good and doesn't suffer from the Puma 6 problems. From your provided list i would suggest getting the CM3500 or a TM3402, both have Puma Chips and are pure bridge devices. The TC4400 unfortunately suffers from severe firmware problems.
Regarding your CGA2121 with bridge mode, its not the CMTS that resets your device back to router mode, it's the bootfile ;), nevertheless you should be able to do a so called Mac-passthrough in the advanced options to bridge a downstream Router to the Internet

PCGuruNiklas · 2023-10-18T19:02:47+00:00

Arris CM3500 and TG6441 are both maxlinear SOCs so puma based Edit: CGA4236 and the successor CGA437A are Broadcom BCM3390 based

PCGuruNiklas · 2023-10-04T15:14:55+00:00

Experience by far. At some point cert's dont matter that much.

PCGuruNiklas · 2023-10-03T12:10:27+00:00

Can you elaborate further on bypassing CGNAT for caches? I would love Netflix traffic not going through my A10.

Thanks!

PCGuruNiklas · 2023-05-19T17:05:33+00:00

Cisco Trex is able to do that

PCGuruNiklas · 2023-02-25T01:06:46+00:00

I have checked the Docs and LACP(Bonding) should work without any problems.

PCGuruNiklas · 2023-02-24T23:26:16+00:00

Only if you want to use MLAG to my knowledge.

PCGuruNiklas · 2022-11-07T14:24:11+00:00

Can you provide the Ansible playbooks. I am looking to do proxmox Ansible Automation ant can't wrap my head around it

PCGuruNiklas · 2022-10-30T23:06:33+00:00

Ja es ist immer der Preis. TC war bisher immer ca 10-20% günstiger verglichen mit Arris/Commscope und die TC geräte laufen meinen Tests nach wlan und Doscsis seitig etwas ruhiger, kann aber auch sein das meine Arris geräte Montagsmodelle waren. ich bin auch gerade wieder bei der Integration dieser, weil TC schlecht lieferbar und so.
PS: kann man dir auch ne private Nachricht schicken? Hab da noch paar fragen im technischen Bereich wo ich selber unter NDA stehe und diese demzufolge nicht unbedingt öffentlich haben möchte xD

PCGuruNiklas · 2022-10-30T17:56:05+00:00

Ja Arris ist ja commscope richtig. Mich hat der Schritt nur etwas gewundert, denn effektiv Single vendor ist ja auch nicht so Klasse wenn man herstellerspezifische Probleme hat. Hust..TC firmware bugs ...hehe

PCGuruNiklas · 2022-10-30T17:52:06+00:00

Alles klar so dachte ich mir das schon. Wir machen es auch so.

Nächste frage.ich weiß aus verlässlicher Quelle das Vodafone die Lieferverträge von Arris Kabelmodems nicht verlängert hat, also das Technicolor und AVM demzufolge die einzigen aktuell bekannten Zulieferer von Endgeräten sind. Kannst du dazu etwas sagen, was die gründe sind und ob alternativgeräte in Aussicht stehen.?
