This question will probably come across as very novice, but utlimately I'm trying to determine if a managed switch is required for how I'm trying to setup my basic home network. I am setting an up an ERLite 3 with my WAN coming into eth0, an unmanaged switch into eth1 and an AP AC Pro direct into eth2 (this is the part I'm unsure if I can actually do). I also have a UniFi Controller on the network managing the single AP, and it is able to manage it fine.
My question is whether a managed switch is required between the AP and ERLite to properly handle VLAN traffic between the router and AP. I have two SSIDs setup on the AP, each setup with their own VLAN. However, when I attempt to connect a device to either SSID, they fail to pull an IP. I have a DHCP server setup for each subnet and two VLANs on the eth2 port in the same subnet (on the ERLite).
I can provide a config as needed, but I figured I would ask to make sure if it's possible to directly hook the AP up to the ERLite, run two SSIDs with their own VLAN and them be able to get an IP for their appropriate VLAN / subnet from the router.
