Dukanmu mun san cewa akan LAN guda ɗaya, haɗin cibiyar zai haifar da yankin rikici. Alhali a karkashincanza, za a iya warware yankin rikici, za a sami yankin watsa shirye-shirye. Don magance wannan yanki na watsa shirye-shirye, ya zama dole don gabatar da masu amfani da hanyoyin sadarwa don rarraba LAN daban-daban zuwa wurare daban-daban na watsa shirye-shirye don rage tsangwama tsakanin na'urori. Za mu iya ba da shawara cewacanzakuma suna da aikin wannanna'ura mai ba da hanya tsakanin hanyoyin sadarwa? Bayan haɓakawa, an gabatar da manufar VLAN. Menene VLAN?

An raba hanyar sadarwa ta gida mai kama da juna (VLAN) a hankali zuwa wuraren watsa shirye-shirye da yawa, kuma kowane yanki na watsa shirye-shirye VLAN ne. Yadda za a raba shi.
Hoto na gaba yana nunacanzaya kasu zuwa rumbun LANs. A hagu, ta hanyar saitunan ciki, wannancanzaya raba yankin watsa shirye-shirye zuwa yankunan watsa shirye-shirye guda uku, VLAN1, VLAN2, da VLAN3. A zahiri, waɗannan na'urori suna kan ɗayacanza, amma a hankali, an raba su zuwa maɓalli uku, don haka za a sami LAN guda uku (virtual LANs) da wuraren watsa shirye-shirye guda uku.
Rarraba yana canzawa zuwa LANs na kama-da-wane
Ƙungiyar VLAN tacanzayana nuna cewa VLAN 1, lambar VLAN, gabaɗaya tana aiki a rukunin gudanarwa, don haka ana ƙidaya VLAN na gama gari daga 2 zuwa 3. Ta hanyar tsoho, duk VLANs na VALN1 ne.
Abin da ke sama shine bayanin manufar VLAN, ko LAN kama-da-wane, wanda Shenzhen Haidiwei Optoelectronics Technology Co., Ltd ya kawo. Shenzhen HDV Phoelectron Technology Co., Ltd. shine masana'anta ƙwararrun samfuran kayan aikin sadarwa na gani.
