VLAN (Virtual Local nzvimbo network) Iro tekinoroji yekutaurirana iyo inonzwisisika inokamuranisa lan yemuviri mune dzakawanda nhepfenyuro zvinyorwa. Imwe neimwe vlan inzvimbo yePrefasten uko vashandi vanogona kutaurirana zvakananga, nepo kutaurirana pakati pemasangano akasiyana kunorambidzwa. Nekuda kweizvozvo, nhoroondo dzinotepfenyurwa dzinogumira kune imwe vlan.

Nei maVlans achidiwa

Kutanga Ethernet Networks yaive data netekinta Kana nhamba yehondo dzikawedzera, zvakakonzera kukanganiswa kwakakura, kutepfenyura madutu, kushatisa kwakakosha kuita, uye kunyangwe network. Kunyangwe hazvo kusiyana-siyana kusiyana-siyana kushanduka kwemaseregi Izvi zvakatungamira mukuvandudzwa kwehunyanzvi hweVLRology, iyo inopinda muLan mune akati wandei mashanga ane musoro; Imwe neimwe vla inomiririra nzvimbo yePrealcast, inogonesa kutaurirana mukati meVlan sekunge yaive lan uku uchiita kuti adzivise kutaurirana-volan kutaurirana uye nekuvhara nhare mukati meVLAN.

Mufananidzo 1: Basa reVlans

Saka, vlans vane zvinotevera zviitiko:

· Mermit Dealmcast Domains: Broadcast Domains dzakavharwa mukati meVLAN, kuchengetedza bandwidth uye nekuwedzera network yekugadzirisa network.
· Kuchengetedzeka kweLan Kuchengetedza: mameseji kubva kune akasiyana maVlans anopatsanurana panguva yekutengeserana, zvichireva kuti vashandisi vari mukati meVLOKNOGONESESA VANOTAURA NEZVINHU ZVINOGONESA MUCHIKAMU.
Kuwedzera Kwakawanda Sarudzo: Kukanganisa kunorambidzwa kune imwe vlan, saka nyaya mukati meiyo vlan haina kukanganisa iyo yakajairika mashandiro ezvimwe vlans.
· Zvinokosha Virtual WorkGrowGroup Kuvaka: Vlans Inogona Kukamura Vashandisi muWorkgroups, kubvumira Nhengo dzeWorldGups Kushanda Pamwe Nzvimbo Yemanyoro, Kugadzira Kuvakwa Network uye Kugadziriswa kuri nyore uye Kuchinjika.

Vlan vs. subnet

Nekuwedzera subdiding iyo network network yeIP kero mune akati wandei Subnet, iyo yakaderera yekushandisa chiyero che IP kero nzvimbo uye kuomarara kweaviri-mwero prope kero dzinogona kugadziriswa. Zvakafanana neVLANS, SUBNETS zvinogonawo kuparadzanisa kutaurirana pakati pehondo. Hondo dzevashandi dzakasiyana dzinogona kutaurirana zvakananga, sehondo mune dzakasiyana subnets haigone. Nekudaro, hapana tsamba yakananga pakati pezviviri.

VLAN	Subnet
Mutsauko	Yaishandiswa kupatsanura layer 2 network.
	Mushure mekugadzirisa VLAN MISANGANO, vashandisi vari mumachira akasiyana vanogona kutaurirana chete kana kufambisa kuchisimbiswa.
	Kusvikira pamakumi mana nemakumi mana nemashanu mahwanda anogona kutsanangurwa; Nhamba yemidziyo mukati meVLAN haina kugumira.
Hukama	Mukati meiyo VLAN, imwe kana anopfuura subnets inogona kutsanangurwa.

VLAN TAT uye VLAN ID

Kugonesa switches kusiyanisa mameseji kubva kune akasiyana maVlans, munda inozivisa ruzivo rweVlan dzinofanirwa kuwedzerwa kune iwo mameseji. Iyo IEEE 802.1Q protocol inotsanangura kuti 4-byte vlan tag (inozivikanwa seVLAT TAG) kuwedzerwa kune Ethernet Data maFram to kuziva vlan ruzivo.

Iyo vid shamba mune yedata frame inoratidza iyo VLAN iyo iyo iyo data chimiro ndechekuti ndeyakagadzika; Chimiro che data chinogona kungoiswa mukati meiyo yakasarudzwa vlan. Iyo vid Field inomiririra VLAN ID, iyo inogona kubva pa0 kusvika ku095

Naizvozvo, kuti ubatanidze nemidziyo iyi, switch interfaces inofanira kuziva tsika dzechinyakare eThernet Iyo vlan tag inowedzera inoenderana neyekutora kweSterface's default VLAN (Port Default VLAN ID, PIVED).

Mhando dzeVlan Interfaces uye VLAN TIMA KUSHANDISA MIGANISHMS

Mumasworks aripo, vashandisi veiyo VLAN inogona kubatana kune dzakasiyana switches, uye panogona kuve nemakwenzi akawanda anotsemuka mapoka eSwitches. Kana mushandisi wekudyidzana anodikanwa, iyo madhiri pakati peSwitches inofanira kukwanisa kuziva uye kutumira mafuremu kubva kune akawanda mavlans panguva imwe chete. Zvichienderana nezvinhu zvakabatana uye kuti mapuranga anogadziriswa sei, kune akasiyana siyana emhando dzeVlan nzvimbo dzekugara dzakasiyana uye network.
