摘要
A novel method of enabling a port of a network switch to support connections with multiple VLANs. The method comprises storing VLAN data indicating a plurality of VLAN identifiers corresponding to the multiple VLANs supported by the port. A VLAN identifier of a data packet received via the port is compared with the plurality of VLAN identifiers determined using the stored VLAN data. The data packet is forwarded for further processing if the VLAN identifier matches one of the plurality of VLAN identifiers. However, the data packet is discarded if the VLAN identifier does not match one of the plurality of VLAN identifiers. Moreover, VLAN information corresponding to a VLAN identifier of a data packet to be transmitted from the port is compared with the stored VLAN data to determine whether the VLAN identifier matches one of the plurality of VLAN identifiers supported by the port. The data packet is prevented from being transmitted from the port if the VLAN identifier does not match one of the plurality of VLAN identifiers.
