Abstract
Virtualne lokalne mreže su način logičkog grupiranja korisnika neovisno o njihovoj fizičkoj topologiji. Zapravo, radne stanice kod VLAN-ova ne trebaju biti smještene na istome LAN segmentu. VLAN se ponaša kao neovisna LAN mreža. Paketi razašiljanja se šalju unutar VLAN domene razašiljanja. Standard IEEE 802.1Q definira sustav VLAN označavanja za Ethernet okvire. Svaki VLAN ima svoj VLAN ID, broj koji označava VLAN. VLAN-ovi se konfiguriraju na komutatorima. Postoje dvije vrste konfiguracija VLAN-ova: statička i dinamička konfiguracija.Virtual local networks are a way of logical grouping of users regardless of their physical topology. In fact, end stations in VLANs do not need to be locate on the same LAN segment. VLAN behaves like an idenpendent LAN network. Broadcast packets are flooded only within a VLAN broadcast domain. The standard IEEE 802.1Q defines a system of VLAN tagging for Ethernet frames. Each VLAN has a VLAN ID, number that identifies the VLAN. VLANs are configured on the switches. There are two types of configuration of VLANs: static and dynamic configuration
