I'm a networking amateur, and one thing I've struggled to figure out is VLANs for wireless devices. It seems like VLANs are managed at switch level, so does that mean that all devices on a particular AP have to share the same VLAN? Or is there a way to segregate devices across multiple VLANs within a single AP?
Enterprise APs support VLAN tagging themselves, so you assign multiple VLANs to the AP uplink in the switch and then tell the AP which SSID belongs to which VLAN.
Yes. I set up VLANs on my Cisco switches. The APs are told what vlans and WLANS are configured through Ubiquiti management panel. The APs are all connected to their assigned ports on the switches and the ports are configured to see all necessary VLANS tagged and one (management) VLAN untagged. The untagged VLAN is how the management application talks to APs.
Eeach of 4 APs serves all 4 WLANs and each WLAN + VLAN are completely separated networks.
The traffic from various WLANS goes directly to their assigned VLANS and never mixes together -- the only way is either through the router or some other service like my proxy.
