No need to check on ONU as even though the
OLT assigns Vlan to the ONU, it does not relay to the router.
I guess here is the answer where that dynamic VLAN came from. The dynamic VLAN is named
IP VLAN, which shown in the VLAN list type as
dynamic.
Most of the time VLAN ID tagged in Ethernet Frames are just ignored (but not stripped) by non-VLAN capable devices. If the device is set to allow frames with tagged VLANs (i.e. trunk ports), it will pass the Ethernet frames with allowed tagged VLAN IDs. Since there is no trunk port setting in the TP-Link router, i guess the former is true.
My switch default VLAN ID is 1 (if primary VLAN in your feedback mean the default VLAN ID), like most switches that support dot1q standard. The switch does support static VLANs (as in my setup) and dynamic VLAN via RADIUS authentication (which is none for current set up).
I will do my own packet sniffing soon to investigate. It is already off day though.
