VLAN Question

Unanswered Question
Aug 29th, 2007

All, if I have a VLAN 300 with a management interface of 10.3.240.240 and a VLAN 400 with a management interface of 10.247.1.1, and each port is in the same subnet as the specified VLAN, what prevents traffics from entering the other VLAN?

I have this problem too.

Then how do I prevent two VLANs from broadcasting traffic into each VLAN, that is on the same swith?

ok, so if my objection is to have machine traffic on Vlan 247 and Data Traffic on VLAN 300, IPX traffic from printers on VLAN 300, will not go over to vlan 247?

IPX traffic cannot get out of its vlan because you are not routing IPX. Only IP traffic could be routed between the vlans. If you want to avoid that, you have lots of solutions like disabling routing, implementing access lists, removing the IP addresses etc...

Vlan are still providing you with isolation at layer 2, even with your current configuration.
