Hi @ITV 

Thanks for reaching out to TP-Link Business Forums.

What kind of feature do you want to achieve?

Do you mean you just want to use VLAN 1 to set up the whole network?

If so, then you don't need to configure anything but just adopt the devices into the OC200. 

It's just a simple setup, but just note that the default VLAN 1 in OC200 is 192.168.0.1. If it's different from your ISP's, you may need to modify it to the same subnet.

  @Gabriel-TP - thank you the pointers.

However, things are not that simple - even with factory defaults.

This is because the factory defaults assume there is an Omada router involved.

In addition, the default vlan-1 settings assume this Omada router is also dhcp and dns server.

With an ISP router (versus Omada router) I can set the IP of the ISP router as the gateway for vlan-1.

Which includes dhcp capabilities - but not managed by Omada as suggested by the dhcp settings.

I could disable the dhcp part of these vlan settings and set the ip of the isp router as the lega dhcp server and default gateway.

However, I don't know how this would work out in real life - any idea?

With any additional vlans I can use the "external"-feature for dhcp - but this is not available for vlan-1.

Any suggestions how to deal with this in the proper, non-Omada-router way?

Other then using a different vlan tag for management?

With warm regards,

If you are going to use the ISP router for your network, then you only have to ensure that the Omada devices are on the same local subnet.  The ISP router should be the DHCP server and gateway for the network and you will need to disable DHCP in the controller settings for the default VLAN.

If the ISP router allows you to make DHCP reservations, you might consider assigning fixed IPs to the controller and other Omada devices which makes them easier to manage.

The default VLAN in Omada devices is VLAN 1 and you cannot delete it.  You can however, change the subnet address of VLAN 1 and you can also change the ID from 1 to another ID.  In your case, you do not need to do anything to have a VLAN 1.

  @jra11500 - thank you for the detailed explenation.

Does this mean that there further Omada specific communication between the controller and the router once dhcp is disabled.

At least not to the extend that it is interfering with the normal trafficflow between devices in that default vlan?

Cheers - Will

After the other Omada devices are adopted, the controller will only communicate with those devices.  It will not communicate (for control purposes) with the third-party router and will not interfere with normal traffic.
