Assume the PHY link on the port speed makes sense (same speed as on the Asus), the device does get an IP address assigned by DHCP (check the Asus router DHCP table/connected devices), check the switch ARP table for the device MAC address, ... have an eye for the IGMP Multicast settings for the VLAN in use. Allow IGMP multicast, and don't block unknown multicast.

The device is 100mbps. Asus is 1000mbps. Device gets assigned an address. Fing on my phone can find it.

Switching / Address table shows the device connected

I followed this to confgure IGMP Multicast

  CAncel the my idea that it's MDNS based - much more the discovery is using the classic IoT UDP IPv4 broadcast, source port 41457, destination 6667.

    OK. Sounds like you're closer. What do I need to tweak to get it working when it's connected to the switch?
