Support for RTL838x based managed switches

yolf · May 3, 2025, 5:43pm

I want an OpenWRT switch with more than one SFP+ Port.

The Xikestor SKS 7300-4X4T would meet my needs better than the SKS8300-8X,
but it is not supported (yet?).
The SKS8300-8X is supported in a snapshot release, hopefully in a stable release soon.

It seems to have problems with certain SFP+ Modules.
I am not sure, where the problem is, maybe it cannot use more than one different
speed in all used ports or all ports only support 10G, I do not know.

Also it is not available new anymore.

The SKS8310-8X seems to be available, has a built in fan. It probably
needs that fan, because the predecessor would overheat.
Maybe the image of the SKS8300-8X could work, but noone tried yet.

I would try it, if there is a chance, that following requirements can be met in the end:
Support for DAC connections to random other switches or NICs.
Support for 10G Base-T SFP+ modules in general, better 2.5G/5G/10G Modules

I run my onti (same as the sks8300) with 1, 2.5 and 10gbit copper SFP as well as a 10gbit DAC. Definitely mixed speed works.

In fairness, 2.5gbit needed a simple kernel patch, it's up thread.

I would however strongly recommend to make sure it has some airflow (I have a slow 140mm fan blowing across it), it gets very hot otherwise. Beats the apparently noisy fan in the 8310 in my book.

Hi, I recently acquired the D-Link DGS-1210-08P rev G1. After some research here I found that this one is not explicitly supported (according to the wiki). However, by comparing the pcbs and going with what rkunze said, I think this one is identical the 10P rev F1 model.

Here are some logs:

Before writing to flash, is this the expected result? Is there anything in the bootlog that would indicate an error? Or is there anything specific I should test?

If not, should the 08P rev G1 just be added to the wiki as identical to the 10P rev F1 or should we also add it to the device tree, respectively these files:

(new) /target/linux/realtek/dts/rtl8380_d-link_dgs-1210-08p.dts not sure why 10p has rtl8382 in its file name when wiki says it's rtl8380M.
(modified) /package/boot/uboot-tools/uboot-envtools/files/realtek just adding the device name around line 20
(modified) /target/linux/realtek/image/rtl838x.mk just adding another block like for the others

Regarding the .dts file: I guess this would probably look exactly like rtl8382_d-link_dgs-1210-10p.dts just with a different model name.
Just like rtl8382_d-link_dgs-1210-20.dts and rtl8382_d-link_dgs-1210-16.dts which also seem to be the same device.

Did you beat me to the 15€ one on ebay.de?

slh · May 4, 2025, 11:06pm

The rtl838x (sub-)target is relatively uniform, especially for model ranges of the same vendor, but each device will still require its own firmware image with its own DTS. The good news, you can probably copy most of that from the DGS-1210-10p, but you will need to check the port assignments (plug in a cable with something on the other end, check logread -f for up/ down messages and compare it against the port number) and drop the two ports the -08p variant doesn't have. It's not going to be difficult, but it will still need doing.

mardonner · May 5, 2025, 9:17pm

I'll check the port assignment just to be sure but 10p and 08p both have 10 ports (8 RJ45, 2 SFP). From what I can tell, it's the exact same pcb. See also this post from a while back:

The only thing that's maybe different is rtl8382 on the 10p F1 vs. rtl8380 on the 08p G1.
My stock boot log indicates rtl8380, so I'm going with that. The heatsink mounting is soldered and I'm not removing that.

rtl8382 vs. rtl8380 seems to only make a difference in two functions: one for vlan and one for qos

What I don't understand is why the 10P code indicates rtl8382 in its .dts filename and in the rtl838x.mk file even when the boot log indicates rtl8380, see this old post in this thread:

Not familiar with the build process, so I don't know if that actually has any impact or if it only does if it is also referenced in the .dts file, like with the one of the 10MP.dts

Also maybe one oddity: /etc/config/poe contains:

config global
        option budget '170'

config port
        option enable   '1'
        option id       '1'
        option name     'lan1'
        option poe_plus '1'
        option priority '2'

Shouldn't this by default be 65, like indicated here ?

I haven't used realtek-poe until now and I couldn't find any manual, so I don't know what's to expect here. Guess I'll have to look through the code.

Small world, eh? Many opportunities to get switches like these for cheap. You'll get yours soon as well, hopefully

gargabill · May 6, 2025, 3:53pm

I think all the 10-port versions (08P-g, 10P-f, 10MP-f) use the rtl8380 (which only support up to 10 ports as far as i can tell), the rtl8382 is used for versions with up to 28 ports). DGS-1210-10p with rtl8382 is probably wrong but may work anyway.

I am going to try flash my DGS-1210-24P-g with the DGS-1210-28P-f firmware. They both have 28 ports and looks identical otherwise as well. For some reason D-link doesn't count the SFP/combo-ports in the G revision when assigning model names. DGS-1210-24-g = DGS-1210-28-f and DGS-1210-48-g = DGS-1210-52-f. Hence its probably very easy to get all 4 of the "non supported" G-versions supported under their right names.

gargabill · May 8, 2025, 5:42am

I can confirm that the D-Link DGS-1210-24P rev G already is supported (but under wrong name) if you use the DGS-1210-28P rev F firmware. Power LED, reset button, all ports and port LEDs work. PoE also work but the config have to entered manually after install.

mardonner:

Also maybe one oddity: /etc/config/poe contains:

config global
        option budget '170'

        option enable   '1'

        option name     'lan1'
        option poe_plus '1'
        option priority '2'

Same with the DGS-1210-24P after fresh install. Change to whats specified in realtek/base-files/etc/board.d and that is working.

howels · May 8, 2025, 11:54pm

This was fixed in the realtek-poe packaging for OpenWRT - need to investigate why we aren't seeing the correct Poe config, should be generated from board.json - ok looks like it stalled

Please review, comment and try to help. This has been a journey of changes, arguments and reverted commits but looks like openwrt/packages is where it should live.

GasGas277 · May 11, 2025, 11:27am

Have anybody tried the 8xRJ45 variant of the 8 port XikeStor 10G switch that is SK8300-8T ?

hmartin · May 15, 2025, 7:53pm

I measured across those capacitors on my XGS1250-12 (no version indicated), and it is 0.718V

howels · May 16, 2025, 6:41pm

@bmork was wondering if the thermal driver you wrote could also work on rtl839x as well as rtl838x ?

bmork · May 16, 2025, 6:54pm

The register layout will be different. Someone with the hardware has to add support and test it.

howels · May 16, 2025, 6:55pm

I have a couple of the switches and am willing to build and test, but I'm not sure about picking the correct register locations here.

kitor · May 16, 2025, 7:27pm

Thanks for confirming! Then I need to dig deeper as it has to have another fault.

bmork · May 17, 2025, 7:03am

Look at @svanheule 's excellent register browser. There are two sensors here:

Problem is guessing what all the configuration means, unless you also find a datasheet documenting this.

howels · May 17, 2025, 7:36am

Thanks, I'll try to to adapt the maple thermal driver to do core0 on cypress and see if the masking and shifting is the same on rtl839x or if I get garbage data.

howels · May 17, 2025, 9:11am

I've also observed random reboots on the two rtl839x switches I've got - anytime from every 6 hours to every 5 days. Very hard to diagnose!
Going to leave a serial port logger on one to see what it's doing.

andyboeh · May 17, 2025, 9:53am

On which version? I've got >60 days uptime with 24.10.0 on my JG927A.
