Claim 12:
13. The method of claim 1, comprising:
executing, on the network switching device, a secure kernel to control access to hardware on the network switching device;
executing a first forwarding rule custodian on the secure kernel, the first forwarding rule custodian maintaining first forwarding rules for the first VLAN; and
executing a second forwarding rule custodian on the secure kernel, the second forwarding rule custodian maintaining second forwarding rules for the second VLAN,
executing a port assignment manager on the secure kernel,
wherein assuring that a packet received at a hardware port assigned to the first VLAN is not sent in a legible form from any hardware port assigned to the second VLAN includes the port assignment manager cooperating with the secure kernel to restrict access for the first forwarding rule custodian from hardware ports assigned to a VLAN other than the first VLAN, and to restrict access for the second forwarding rule custodian from hardware ports assigned to a VLAN other than the second VLAN.
