i have a manageble switch 3com, i wanted tu test the vlan to show to a girl that i am mister vlan!!,
so i create vlan 2 and vlan 3, and there is a default vlan 1. i putted my computer on a port in vlan 2, and another computer in vlan 3, and i have tried a ping between them, i expected not to work, and it work, i have waited 5 mn, and it could still ping between 2 differnet vlans.
did u check whether there is a router connected to the switch and probably when a routing on a stick was configured, it would by default does it for all vlans and that could be one reason why this is happening.
also is it possible for you to paste n show what you did.
after pinging look at the arp table of the pc (arp -a) and see if it has an arp entry for the other pc. That will tel you if its talking directly, whether the vlans are isolated from each other or not. If it doesn't have an arp entry for the pc then do a trace and see what it is using as a gateway router.
