[A store salesman, Hairy, is showing Cueball a dehumidifier, with a “SALE” label on it. Several other unidentified devices, possibly other dehumidifier models, are shown in the store as well.]
Salesman: This dehumidifier model features built-in WiFi for remote updates.
Cueball: Great! That will be really useful if they discover a new kind of water.Source: https://xkcd.com/3109/
Ok maybe I don’t fully understand yet. Let’s say an access point has 3 SSIDs, lan, guest and iot each client on each SSID gets a vlan tag accordingly. So it’s only connected to a single physical port, i think that’s what confused me. But SSIDs are interfaces just like an physical port afaik so your analogy still stands. The security here is the WiFi password anything that connects to LAN gets a LAN vlan tag. but it’s not like anything that connects to any of the SSIDs can get the DHCP lease of some random device on any vlan cuz it got tagged before. Or am I missing something?
