@hudri said in Assigning Clients to VLANs:
where they just manually switched back and forth between the VLANs,
You can - where you set the pc to understand the tag, but again that is not a vlan... That is some user without a clue to networking thinking they have setup a vlan and all they did is run multiple IP schemes on the same network. There is no actual security there, anything can talk to anything, be it you setup a firewall rule or not - broadcast and multicast traffic is going to be seen by every device.
That is not a vlan. A vlan actually isolates traffic at layer 2..
You could move your pc into another vlan that is on that port, by changing the pvid on trunk port so the untagged traffic is now in X vs Y, etc. But just changing on the IP on the pc isn't going to work if you actually have vlans setup.
