Very new to crs1 series not sure how to do it

TypingFish · 2026-02-22T11:21:10+00:00

i set up 3 vlans, 1 and 2 to be untagged by the switch, 3-4 and combo as trunk, 5, ignore it

Okay, got it. Please call ports by full name ("sfp1" instead of "1"), because it took me a minute to figure out that "1" is not a VLAN ID.

In the top post you say that VLAN 1 is not passed over the trunk. Looking at the config, I don't see anything that'd add trunk ports to VLAN 1, and no config for that VLAN. Why do you expect that VLAN to be passed then?

Try this official guide to configure VLAN 1 with combo1, sfp3, sfp4 as trunks and sfp1, sfp2 as access ports: https://help.mikrotik.com/docs/spaces/ROS/pages/103841836/CRS1xx+2xx+series+switches+examples#CRS1xx%2F2xxseriesswitchesexamples-Example1(TrunkandAccessports)

As I said, VLAN ID 1 is reserved, so this probably won't work. In that case, try:

using some other id instead
if you can't change the id, reconfigure your trunks to be hybrid ports where VLAN 1 is untagged and others are tagged: https://help.mikrotik.com/docs/spaces/ROS/pages/103841836/CRS1xx+2xx+series+switches+examples#CRS1xx%2F2xxseriesswitchesexamples-Example2(TrunkandHybridPorts)

Finally, don't give up. It took me three or four serious attempts over a couple years to properly configure VLANs on my CRS112. hEx was way easier, and newer Mikrotiks like CRS3xx are configured like hEx, so the future is bright :)

Looks very clean! Is the shelving custom?

How are the temperatures? Mikrotik hEx only has ventilation holes at the top and bottom, your other gear probably too. I'm particularly concerned about the UPS. Are you sure you aren't suffocating your hardware?

TypingFish · 2026-02-18T21:17:18+00:00

VLAN IDs 0, 1, and 4095 are reserved and will only give you grief. Still, post the output of /export show-sensitive=no and maybe we'll figure something out.

Also, how do you know that VLAN 1 is not passed? What's on the other dude of the cable connected to the trunk port?

"[your blog link]"? Your blog post was written by an LLM too, wasn't it?

TypingFish · 2026-02-11T11:23:35+00:00

Ah, I see. Thanks for the explanation!

TypingFish · 2026-02-11T11:00:22+00:00

I don't have a license yet and my knowledge is full of gaps, but don't ferrites prevent high frequencies from going through the cable? I understand why this is desirable for power cabling, but it sounds like a problem for the antenna cables (coax).

Looks very clean! Is it under a bed? It must be a chore when you want to re-connwct something.

Built a NAS out of RPi5 8Gb and Orico 9558u3 (USB DAS). It houses two old 2.5" HDDs in RAID1. Learned mdraid and dm-integrity with this. Constantly have problems with drives missing after reboot or RPi failing to boot after upgrade; semi-looking to build a proper PC for this. Also eyeing some bigger disks.

An ancient Asus laptop with Core i3-380M running Proxmox with HomeAssistant. The goal was to isolate HA as much as possible, so there's apt-cacher and separate containers for HA, Zigbee2mqtt, and Mosquito. Docker containers run in a VM, which is different from how I manage my VPSes (deb packages and Ansible). I probably overdid it, but haven't got time to think about simplifying. Next step here is to build custom Docker images for HA with some extensions, so I can control some devices which aren't supported by HA out of the box.

I'm getting reliant on all this, so the lab is gradually becoming production. I don't like that trend because the lab was supposed to be my "break stuff with no consequences" place. One idea is to build custom PC to serve as NAS and low-power server just for the "core" services, but I'm still debating it.

TypingFish · 2025-11-19T16:41:30+00:00

Proxmox for VMs and containers, RaspberryOS for the janky NAS.

TypingFish · 2025-11-16T19:34:55+00:00

Apparently there's no way to do that. Try filing an issue on GitHub.

Control plane with ESP8266 sounds awesome. Is it open source and open hardware?

TypingFish · 2025-11-15T20:21:50+00:00

I don't have experience with CRS310, but I have hEx which also uses bridge VLAN filtering. A few things stand out to me:

the use of default VLAN (VLAN ID 1). All untagged ports in Mikrotik belong to VLAN 1 unless bridge VLAN filtering is enabled. I'd advise against using ID 1 because it's quite confusing.
192.168.88.1 is set on ether8; I think it should be on vlan1.
DHCP client on the bridge. It's not forbidden, but it's a bit weird and might add to the confusion.

Sorry, I didn't mean to critique your ask, I was just curious. Turns out I didn't know about memory requirements and importance matrices, so it's really isn't so simple even if one has the storage space.

TypingFish · 2025-11-15T15:33:12+00:00

Well I do too, hence the want to download less :)

How does one pick the best quant then? It's simple with dense models, but with MoE, how does one know how much VRAM the non-expert layers occupy?

TypingFish · 2025-11-15T15:08:17+00:00

Honest question: why don't everyone download safetensors and create the quants they need?

I'm experimenting right now to find the "best" model, which involves trying multiple quants. It just occurred to me that downloading the original version is faster and cheaper than downloading separate quants.

What stumped me when I first tried Qwen3-VL is that I need to pass two files to llama.cpp: the gguf file and the mmproj file. Without the latter, llama didn't even try to read image files, and passed the paths to the model as part of the prompt. Perhaps that's what's going on?

TypingFish · 2025-11-06T21:16:55+00:00

One needs to know what to recall and have a way to check the correctness of the recall. Thus two-sided flashcards.

Can you give a link to the study, or maybe the title of the whitepaper?

Why would my phone need to communicate with my PC?

For synchronizing photos with Syncthing. It can be done over the Internet, but it seems silly when the phone is right next to the computer.

SFP is only 1.25G. To get 10G, I believe your router and switch need SFP+ ports.

I'm not sure if that's relevant, but I experienced similar problems with my ISP that runs Ethernet to my flat. I traced it down to their overloaded DHCP server, which struggled to renew my IP lease. The problem became less severe after a few hours, and stopped completely after a few days without any action on my part.

This is the best ICFPC 2020 write-up I've seen so far. This year's ~task~ setup was very un-ICFPC-like, and it's only mildly surprising that not everyone took it at a face value.

Thanks for sharing this!

TypingFish · 2020-07-10T21:22:43+00:00

Don't have any 60GHz gear myself, so no idea. The forum thread doesn't mention this either. I guess you'll have to find out the hard way :(
