Abstract:
1. A method in a network switch having a processor and a memory therein, wherein the method comprises: receiving a packet having identified therein a source Media Access Control (MAC) address and a Virtual Local Area Network (VLAN) Identifier within a Customer VLAN Identifier (LVID) tag of the packet received, wherein the VLAN identifier corresponds to a VLAN which is non-existent on the network switch; modifying the packet received to include two VLAN tags, a first VLAN tag corresponding to the VLAN identifier within the CVID tag of the packet received and a second VLAN tag, distinct from the first, wherein modifying the packet with the first and the second VLAN tags associates the source MAC address with the CVID tag of the packet received; determining no forwarding database entry exists for the modified packet; and creating the VLAN on the network switch to handle received packets tagged with the VLAN identifier.
