Assign dynamic VLANs to wired clients

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi,

Could someone help me, please? I'm having a problem with TP-Link C7 router with OpenWrt version 18.06.1.

I am trying to assign Dynamic VLAN's to clients which are connected to WiFI AP as below mentioned setup. All routing and DHCP assignments are done in Wired Router. But I am not able to figure out how do I put different clients(connetced via WiFi AP) in different VLANs dynamically. How do I configure /etc/config/network to point it to Radius server so that It will send VLANs information for connected clients

Setup: 
 Router(Wireless disabled) -----> WiFi AP ----> Clients

P.S. I am able to assign dynamic VLANs in wireless routers with radius server configuring hostapd.

Thanks in advance.

/etc/config/network

is just for the router to have its own interfaces on the vlans.... and is not involved in client assignment.

some targets ( router architectures ) may not support this. ( dynamic vlan assignment )

what c7 do you actually have?

do you have space for adding packages or and overlay filesystem etc?

is your radius server setup ( what is it? ) and are you able to test that with another access point / os?

I have tp-link archer c7 ac1750 v3 (ar71xx) . Yes, I have space for adding packages and overlay FS.

I am using Freeradius on Ubuntu Machine as a Authentication server which assign VLANs dynamically after successful Authentication. Also, I am able to assign dynamic VLANs on Same router(C7 wireless enabled) with hostapd(wireless controller) configuration.

But I want to use this router as per the configuration mentioned in the description and I am not able to figure out how to do that for wired clients.

that certainly is confusing....... what is wired and what is not?

Okay. Maybe I am not clear enough. I will rephrase the description.

I have Tp-link archer c7 ac1750 v3 (ar71xx) but I have disabled WiFi Radio on it due to some requirements. So It is just a Wired Router for our scenario. I have connected a WiFi AP to this router via Ethernet. WiFi AP broadcasts SSIDs and clients get connected to it but Routing, DHCP assignment is being done on TP-Link router. So I guess these clients will be consider as Wired clients in Router.

Now, I want to assign these connected clients to different VLANs dynamically with the help of Radius Server which I am not able to figure out how to do it.

Before this setup, I did not disable WiFi radios on TP-Link router and I was using it as wireless router and connecting clients directly to it. So I was able to assign VLANs dynamically by configuring Radius Server info in hostapd.conf (via /etc/config/wireless) and it worked like a charm.

I hope I have explained it clearly now.

management intensive without underlying framework....
without explaining more of the capabilities your "AP" has.... it's all you got.

I understand this but my question is how to point to radius server. I mean where should I configure this info i.e. in which config file?

Thanks

From what I gathered wireless doesn't support VLANs. What you can of course do is set up a wired VLAN and bridge your wireless interface to that (like one would do with a guest network e.g.). You can easily add more than one AP to /etc/config/wireless if the wireless driver supports multiple per physical radio.

Thanks for you response @Borromini . I have dynamic VLANs already working for wireless using the same idea(bridging wireless interface with wired VLAN) and pointing to radius server for authentication and assigning VLANs dynamically in /etc/config/wireless.

But I am not able to figure out how to use radius server for wired clients and where should I configure radius server info like we do in /etc/config/wireless for WiFi clients.

You can refer my setup info as below:
