hi, we upgraded Omnia ver CZ11NIC13 to OS 5.0
in luci is missing switch configuration, is it a bug ?
thank you
As far as I can tell no. The omnia was/is one of the first devices that where started with the DSA switch architecture instead of the OpenWrt’s old swconfig approach. (The upstream Linux kernel network maintainers had decided against swconfig and for DSA, so it was clear that DSA was “the way”). Now, DSA and swconfig are not compatible and until recently there simply was no way to parse the switch configuration from UCI and apply it to DSA switches. I believe there is now upstream work in OpenWrt that will allow LUCI/GUI configuration of DSA switches, but that is pretty much work in progress (so not done yet and also not guaranteed to reach completion, but I think it will work out, as OpenWrt seems inclined to switch to DSA as well*)
*) The reason for that switch is that DSA support can be upstreamed to the main line linux kernel, while swconfig is something OpenWrt needs to carry and maintain as independent patches that require more care and maintenance than upstreamed components would.
thank you, please tell me, where can i look for switch configuration from shell
i am not able to found the right configuration files
thank you !!
Well, DSA is different, the idea is to treat switch ports much more like ethernet interfaces in linux and allow the standard tools to manipulate them. tools like ip and friends.
Personally, I have no first hand experience* in configuring the omnia’s DSA switch (or any DSA switch for that matter) so i will refrain from posting my guesses. There should be some users on this list much more versed in that issue.
*) I am a simple mind, if I can avoid VLAN trickery, by say running extra dedicated cables I tend to do so 
There are a lot of forum posts about this but none of them really make it simple/clear on what to do.
- They have not built any direct configuration support for DSA into the product yet, both in UI or configuration files.
- It sounds like they intend for any such support to be made through openwrt’s codebase instead of coding it in themselves. It looks as if this is being worked on for openwrt, but I don’t see any releases yet.
Here is what I do for my config, which is I’ll admit, a bit odd.
I send all of my traffic from my Omnia (which is upstairs where i get the best wireless signal across the house) over one cable to a managed switch that is downstairs with the rest of my equipment, modem included.
I tag the traffic for LAN to VLAN1, the traffic for the modem to VLAN2, and the traffic for my guest wireless to VLAN3.
All 3 of them pass over one cable from the switch upstairs to the Omnia, and goes into port 3.
This required two methods if configuration to work properly
In the interfaces section of the UI (or the /etc/config/network file)
- make the interface for LAN traffic ‘lan3.1’ which tags it as VLAN1
- make the interface for WAN traffic ‘lan3.2’ which tags it as VLAN2
- make the interface for DMZ traffic ‘lan3.3’ which tags it as VLAN3
By itself this worked for wireless clients, but the LAN ports no longer worked, so I had to also do the following below
-
set PVID to 1, and tag all packets that go out of lan3.1 and br-lan
bridge v a dev lan3.1 vid 1 tagged
bridge v a dev br-lan vid 1 tagged self -
set PVID to 3 and tag all packets that go out on lan3.3 and br-dmz
bridge v a dev lan3.3 vid 3 tagged
bridge v a dev br-dmz vid 3 tagged self -
remove VLAN settings that existed before I made my changes, as they are no longer valid
bridge v d dev br-dmz vid 1 self
bridge v d dev lan3.3 vid 1
After that, everything worked, LAN ports included. Depending what you are doing, you may not need to descend into bridge commands. If you do, make sure you put them in /etc/rc.local so they apply on boot. (but PLEASE test this before you do, so you don’t lock yourself out)
My understanding of this is limited it its possible I am doing more than I should, or less than I should, in my bridge commands. Feedback is welcome and if I can get a better understanding I can post a wiki article about this stuff so others can find it too.
This is what my bridge v output looked like after the changes

Configuration
- I have a turris omnia, running since years, with auto-updates on for security reasons.
- I configured everything using LuCi, without editing any configfiles.
- I did use quite some “fancy” features, like having VLANs and assigning different Physical Ports to different networks, including having one “trunk” with 2 tagged VLANs connected to a switch that also supports VLANs.
Problem
Some time in the last two weeks, my turris auto-updated itself (presumably form something older to OS 5?), and now the “switch” setting is gone.
How do I achieve the following:
-
See what could be seen in the “switch” setting available previously, namely which ports have cables attached, and if they are 100mbit or gigabit etc?
-
Configure the switch. I.e. Port 1-3 are connected to vlan1, port 4 is connected to vlan2, and port 5 is a “trunk” to my other switch, that taggs either vlan1 or vlan2?
Since yesterday something is broken in the setup, rendering the TV and other stuff unusable (presumably due to the autoupdate?!), and I need to fix that fast.
Thanks for any help
I suggest to wait for TOS6 release; in TOS5 there is no such info panel in LuCI. You can use the ethtool package to retrieve such information, or use the reForis.
Please see VLAN - Turris Documentation

Hi! Thanks for the superfast reply.
How do I get this stuff back while I wait? Can I downgrade to what I had a few days ago?
Just looked into reForris, looks very different from what I am used to, but might work for me.
→ will spend some hours on this in the evening, and see if I can get my setup back running.
I have a similar setup as described by you:
- 2 VLANs (“normal” and guest)
- 1 trunk port to connect to another switch
I followed the guide at VLAN - Turris Documentation and it works fine.
I tried to setup VLANs by editing the config files and failed some months before.
This time I used LuCI and it works.
I seem to have some problems after reboot. I was not able to communicate from one LAN-port to another on the same VLAN after reboot.
But I could work around this issue by removing the trunk-port and adding it again in LuCI.
This is not perfect, but I do not reboot that often, so it is kind of OK for now. (I hope this will be fixed in TOS6.)
