VLANs can be configured using various implementations. Two prevalent VLAN implementations are MAC-based and tagged-based. As the name indicates, MAC-based VLAN allows a network administrator to create and maintain VLAN membership based on hardware MAC Addresses. Tagged-based VLAN, on the other hand, allows a network administrator to assign and maintain VLAN membership using a special tag added to each Ethernet frame. After each data packet is appended with special VLAN information, any IEEE 802.1Q compliant hardware (such as network Switches, workstations, or servers) can be part of specified VLAN environment. IEEE 802.1Q is considered an industry standard for VLAN implementation. TEW-424WS is fully compliant with IEEE 802.1Q VLAN. TEG-424WS can be easily integrated into your existing VLAN infrastructure.
