In the Omada Controller, it seems that most of the features that are listed in the Settings section are all geared towards the Omada Router.  For instance, we have the option to set up a DHCP server on a switch, but when you try to set up a DHCP Reservation (under Settings>Services) to assign a static IP Address to a Client, it doesn't work.

After reaching out to TP-Link support, I was yet again told that what I'm trying to accomplish is not possible; that feature only applies to an Omada Router.  If the switch is in standalone mode, you can assign static IP Address via DHCP reservation, however not through the Omada Controller.

As we all know, once you marry the device to Omada, we no longer have control over that device directly.  In my opinion, if we're going to be locked out of the device, all of the device's functionality should be available in the Omada controller.

Hopefully this feature will be added soon.
