Kumanethiwekhi esimanjemanje, ukusebenza kahle nokuphepha kubalulekile, ikakhulukazi ezindaweni lapho amadivayisi amaningi nabasebenzisi babelana ngenethiwekhi efanayo. Kulapho ama-VLANs (Virtual Local Area Networks) engena khona ukudlala. Ama-VLAN ayithuluzi elinamandla okuthi, uma lihlanganiswa nokushintsha, lingaguqula ukuphathwa kwenethiwekhi nokuhleleka. Kodwa iyini ngempela i-VLAN? Isebenza kanjani namaswishi? Ake sihlole.
Iyini i-VLAN?
I-VLAN iyisegimenti ebonakalayo yenethiwekhi ebonakalayo. Kunokuba wonke amadivayisi axhumane ngokukhululekile kunethiwekhi efanayo, ama-VLAN akuvumela ukuthi udale amanethiwekhi angawodwana abonakalayo ngaphakathi kwengqalasizinda efanayo ebonakalayo. I-VLAN ngayinye isebenza njengebhizinisi elizimele, ngaleyo ndlela ikhulisa ukuphepha, yehlisa ukuminyana, futhi ithuthukisa ukusebenza kwenethiwekhi kukonke.
Isibonelo, ehhovisi, ungasebenzisa ama-VLAN ukuze uhlukanise inethiwekhi:
Iminyango: Ezokumaketha, Ezezimali, kanye ne-IT ngamunye ungaba nama-VLAN awo.
Uhlobo Lwedivayisi: Inethiwekhi ehlukene yamakhompyutha, amafoni e-IP, namakhamera okuphepha.
Amazinga Okuphepha: Dala ama-VLAN okufinyelela izihambeli zomphakathi namasistimu angaphakathi ayimfihlo.
Asebenza kanjani ama-VLAN namaswishi?
Ukushintsha kudlala indima ebalulekile ekunikeni amandla ama-VLAN. Basebenzisana kanjani:
Ukucushwa kwe-VLAN: Amaswishi aphethwe asekela ukucushwa kwe-VLAN, lapho izimbobo ezithile zabelwe ama-VLAN athile. Lokhu kusho ukuthi amadivayisi axhunywe kulawo machweba ngokuzenzakalelayo abe yingxenye yaleyo VLAN.
Isegimenti yethrafikhi: Ama-VLAN ahlukanisa ithrafikhi, aqinisekisa ukuthi amadivayisi ku-VLAN eyodwa awakwazi ukuxhumana ngokuqondile namadivayisi kwenye i-VLAN ngaphandle uma kuvunyelwe ngokusobala imithetho yomzila.
Izimbobo ezimakiwe nezingamakiwe:
Izimbobo ezingamakiwe: Lezi zimbobo ziyingxenye ye-VLAN eyodwa futhi zisetshenziselwa amadivayisi angasekeli ukumaka kwe-VLAN.
Izimbobo ezimakiwe: Lezi zimbobo zithwala ithrafikhi yama-VLAN amaningi futhi ngokuvamile zisetshenziselwa ukuxhuma amaswishi noma ukuxhuma amaswishi kumarutha.
I-Inter-VLAN Communication: Nakuba ama-VLAN ehlukanisiwe ngokuzenzakalelayo, ukuxhumana phakathi kwawo kungafinyelelwa kusetshenziswa iswishi ye-Layer 3 noma umzila.
Izinzuzo zokusebenzisa ama-VLAN
Ukuvikeleka okuthuthukisiwe: Ngokuhlukanisa idatha ebucayi namadivayisi, ama-VLAN anciphisa ubungozi bokufinyelela okungagunyaziwe.
Lungiselela ukusebenza: Ama-VLAN anciphisa ithrafikhi yokusakaza futhi athuthukise ukusebenza kahle kwenethiwekhi.
Ukuphatha okwenziwe lula: Ama-VLAN avumela ukuhlelwa okungcono kwamadivayisi nabasebenzisi, okwenza ukuphathwa kwenethiwekhi kuqonde kakhudlwana.
Ukuqina: Njengoba ibhizinisi lakho likhula, ama-VLAN akwenza kube lula ukungeza nokuhlukanisa amadivayisi amasha ngaphandle kokulungisa ngokuphelele inethiwekhi ebonakalayo.
Ukusetshenziswa kwe-VLAN ezimeni zangempela
Ibhizinisi: Nikeza ama-VLAN ahlukene kubasebenzi, izivakashi, namadivayisi e-IoT.
Isikole: Nikeza ama-VLAN obuhlakani, abafundi, nezinhlelo zokuphatha.
Isibhedlela: Nikeza ama-VLAN avikelekile amarekhodi esiguli, izisetshenziswa zezokwelapha, ne-Wi-Fi yomphakathi.
Indlela ehlakaniphile yokuphatha inethiwekhi yakho
Ama-VLAN, uma esetshenziswa namaswishi aphethwe, ahlinzeka ngesixazululo esinamandla sokudala inethiwekhi esebenza kahle, evikelekile, nenyukayo. Kungakhathaliseki ukuthi usungula ibhizinisi elincane noma uphatha ibhizinisi elikhulu, ukusebenzisa ama-VLAN kungenza ukuphathwa kwenethiwekhi kube lula futhi kuthuthukise ukusebenza ngokuphelele.
