Mark device/interface as "child" of other device/interface

Maverick87

Hello everyone,
I've a USG Flex 200HP firewall, and use:

• An external switch (not Zyxel) for extend network topology
• A NWA130BE for Wireless devices

The NWA130BE is not configured for join to NCC and is not managed by the firewall.

Entering to the NCC portal, under the network topology I see this:

As you can see, all the devices (also an Android phone, the dishwasher, etc etc) are all part of the NETWall (the firewall).
Obviously all these devices, are attached to a single "physical port" as per native device.
For example, the switch are attached to the port 2 (is a 2.5Gbit switch) and the NWA130BE Access Point are attached to an port of the switch.

Example:
FW —> Switch 2.5Gbit (on port 2 of the FW) —> NWA130BE (on port 2 of the switch)
FW —> Switch 2.5Gbit (on port 2 of the FW) —> MBP-di-Valerio (Macbook)
FW —> Switch 2.5Gbit (on port 2 of the FW) —> My work PC
FW —> Raspberry PI (on port 3 of the FW)

In my strict case, I also have some VNET that is "translated" into a VLAN interfaces.

But all of these devices are recognized as "child" of the FW.

My idea is to "mark" a devices or an interface as a child/sub-child and in this case, the network topology follow the child/sub-child assigments, can be also interesting mark the devices as wired or wireless devices can be usefull.
