Abstract— The need for security and convenience in carrying out data requires all users to be able to create a safer network, both in terms of data communication and in terms of sharing internet connection lines. The effectiveness of performance in work is always required to be able to work quickly and on time without the constraints of one of the high data traffic that causes problems in network devices in one building. Which ultimately causes all work to be hampered in its completion. With the management of VLANs in a LAN connection, it will be able to parse problems especially in terms of data communication and logical data transmission. (Abstract)Keywords: LAN, VLAN, Network
