How to make friends stupid switch and managed L2?

Question

System administration

Is it possible? Switch 1 is unmanaged, a computer ( IP DHCP ) and an access point ( ip stat 192.168.20.100 ) are connected to it, it ( 1 ) in turn is connected to a managed ( 2 ) L2 port belonging to vlan 90, On ( 2nd ) is configured vlan 20 (192.168.20.1), vlan 90 (192.168.90.1), respectively, the computer received the address 192.168.90.2 from DHTsP, and the access point disappeared from the network, how to send packets from the access point from (1), to (2nd) but in your network, i.e. in vlan 20? Or is it impossible?

Answer 1

In this case, you need to configure the L2 port of the switch as Trunk i.e. bind it to VLAN 90 and VLAN 20 at the same time.
The rest of the performance depends on the network architecture and further routing. So, for example, it is worth marking VLAN 90 or 20 for a range of IP addresses, respectively, but it is worth remembering that router resources are spent on this.
Perhaps it's more rational to put a cheap Mikrotik instead of an unmanaged switch and simply assign the appropriate ports to the required VLANs?

Answer 2

The port is registered on VLAN90, how will the packets go to VLAN20?
You also need to poke the access point out of the stupid switch and plug it into the switch (2) in VLAN20

Answer 3

you can, of course, stick out of 1 and stick into 2, but the distances do not allow ((
