And everytime the switch renews DHCP-lease from one of those other VLAN's, then the swith has an entry like this in system-logs.
kernel: arp: 192.168.2.14 is on vlan0 but got reply from 00:1e:2a:ae:53:ed on vlan1
That is the switches IP and the switches MAC. So the router says "hey, this IP belongs to vlan0, but your MAC is on vlan1".
vlan0 though, does not exist anywhere. vlan1 is the trunk so ok it might be correct for MAC showing there, even though it gets its IP from another higher vlan#.
In firewall logs and stuff, if somethings listed, then the correct vlan-numbers are shown for everything.
