Umngane usho indlela yokuhlukanisa ama-vlans, kodwa empeleni, ukuhlukanisa ama-vlans kubalulekile ezinhlelweni zobuchwepheshe benethiwekhi. Amanethiwekhi amaningi adinga ukwahlukaniswa kwe-vlan. Namuhla, masifunde ngalesi sici ndawonye.
Incazelo ye-VLAN:
I-VLAN isifinyezo se-Virtual Local Area Network ngesiNgisi, eyaziwa nangokuthi inethiwekhi yendawo yendawo. Ubuchwepheshe obuqaphela amaqembu okusebenza abonakalayo ngokuhlukanisa ngokunengqondo amadivayisi ngaphakathi kwenethiwekhi yendawo abe amasegimenti enethiwekhi esikhundleni sokuwahlukanisa ngokoqobo. Ukuhlukanisa ama-VLAN, kufanele uthenge amadivaysi enethiwekhi asekela ukusebenza kwe-VLAN.
Inhloso yokuhlukanisa ama-VLAN:
I-VLAN ihlongozwa ukuthi ibhekane nezinkinga zokusakaza nokuvikeleka kwe-Ethernet, futhi ithrafikhi yokusakaza ne-unicast ngaphakathi kwe-VLAN eyodwa ngeke idluliselwe kwamanye ama-VLAN. Ngisho noma amakhompyutha amabili akusegimenti yenethiwekhi efanayo engekho ku-VLAN efanayo, ukusakaza kwawo okulandelanayo ngeke kudluliselwe komunye nomunye.
Ukwehlukanisa ama-VLAN kusiza ukulawula ithrafikhi, ukunciphisa ukutshalwa kwezimali kwedivayisi, ukwenza lula ukuphathwa kwenethiwekhi, nokuthuthukisa ukuphepha kwenethiwekhi. Ngenxa yama-VLAN ahlukanisa iziphepho zokusakaza nokuxhumana phakathi kwama-VLAN ahlukene, ukuxhumana phakathi kwama-VLAN ahlukene kufanele kuncike kumarutha noma ekushintsheni kwezendlalelo ezintathu.
Indlela yokuhlukanisa i-VLAN:
Kunezindlela ezine zokuhlukanisa ama-VLAN, ngayinye inezinzuzo zayo kanye nokubi. Lapho uhlukanisa ama-VLAN abe amanethiwekhi, kuyadingeka ukukhetha indlela efanelekile yokuhlukanisa ngokusekelwe esimweni sangempela senethiwekhi.
1. I-VLAN esekelwe ekuhlukaniseni imbobo: Abakhiqizi abaningi benethiwekhi basebenzisa izimbobo zokushintsha ukuze bahlukanise amalungu e-VLAN. Njengoba igama liphakamisa, ukwahlukanisa okusekelwe embobeni kwe-VLAN kubhekisela ekuchazeni izimbobo ezithile zokushintsha njenge-VLAN.
Ukuhlukaniswa kwe-VLAN okusekelwe kumachweba kuyindlela evame ukusetshenziswa kakhulu yokuhlukanisa i-VLAN. Izinzuzo zokuhlukanisa ama-VLAN ngokusekelwe emachwebeni zilula futhi zicacile, futhi ukuphatha nakho kulula kakhulu. Ububi ukuthi ukunakekelwa kunzima.
2. Ukuhlukaniswa kwe-VLAN okusekelwe ekhelini le-MAC: Ikhadi lenethiwekhi ngalinye linekheli lendawo eliyingqayizivele emhlabeni jikelele, okuyikheli le-MAC. Ngokusekelwe ekhelini le-MAC lekhadi lenethiwekhi, amakhompyutha amaningana angahlukaniswa abe yi-VLAN efanayo.
Inzuzo enkulu yale ndlela ukuthi lapho indawo ebonakalayo yomsebenzisi inyakaza, okungukuthi, lapho ushintsha kusuka kwesinye iswishi kuya kwesinye, i-VLAN ayidingi ukulungiswa kabusha; Okubi ukuthi uma uqalisa i-VLAN, bonke abasebenzisi kufanele bayilungiselele, futhi umthwalo osebenza kanzima unzima kakhulu.
3. Hlukanisa ama-VLAN ngokusekelwe kusendlalelo senethiwekhi: Le ndlela yokuhlukanisa ama-VLAN isuselwe ekhelini lesendlalelo senethiwekhi noma uhlobo lwephrothokholi lomsingathi ngamunye, kunokuba umzila. Qaphela: Le ndlela yokuhlukanisa ye-VLAN ifanele amanethiwekhi endawo ebanzi futhi ayidingi amanethiwekhi endawo.
4. Ukuhlukaniswa kwe-VLAN okusekelwe ku-IP multicast: I-IP multicast empeleni iyincazelo ye-VLAN, okusho ukuthi iqembu le-multicast liyi-VLAN. Le ndlela yokuhlukanisa inweba ama-VLAN kumanethiwekhi endawo ebanzi futhi ayiwafanele amanethiwekhi endawo, njengoba isikali samanethiwekhi ebhizinisi asikakafinyeleli esikalini esikhulu kangaka.
Kusobala ukuthi bonke ubuchwepheshe be-VLAN abufaneleki ngokuphelele ukusetshenziswa kwenethiwekhi. Ngemva kokuthola ukuqonda okuphelele kwama-VLAN, kufanele sikwazi ukwenza izinqumo ezinembile mayelana nokuthi ukuhlukaniswa kwe-VLAN kuyadingeka yini ngokusekelwe endaweni yethu yenethiwekhi.
Khetha imodi efanele yokuhlukanisa i-VLAN
Izisebenzi eziningi zezobuchwepheshe zazi kuphela ukuthi ukwahlukanisa kwe-VLAN kungathuthukisa ukusebenza kokudluliselwa kwenethiwekhi, kodwa abazi ukuthi imodi yokuhlukanisa i-VLAN engenangqondo izonciphisa ukusebenza kokudluliselwa kwenethiwekhi. Ngenxa yezindawo ezihlukene zamanethiwekhi ahlukahlukene, indlela yokuhlukanisa i-VLAN efaneleke kakhulu yokusetshenziswa kwayo ihlukile. Ngezansi, sizochaza ukuthi iyiphi imodi yokuhlukanisa ye-VLAN enengqondo kumanethiwekhi ebhizinisi kusetshenziswa izibonelo.
Ngokwesibonelo, kunethiwekhi yezinkampani, kunamakhompyutha amakhasimende angu-43, angu-35 awo amakhompyutha edeskithophu futhi angu-8 awomakhalekhukhwini. Ithrafikhi yenethiwekhi ayinkulu kakhulu. Ngenxa yedatha ethile ebucayi emnyangweni wezezimali abasebenzi abavamile abangafuni ukuyibona, ukuze kuthuthukiswe ukuphepha kwenethiwekhi, abaphathi benethiwekhi banqume ukuhlukanisa inethiwekhi ibe ama-VLAN ukuze bahlukanise ukuxhumana phakathi kwabasebenzi abavamile nama-PC abasebenzi bomnyango wezezimali.
Izidingo zohlelo lokusebenza: Kusukela encazelweni engenhla, kungabonakala ukuthi inkampani ihlukanisa ama-VLAN ukuze kuthuthukiswe ukuphepha, kuyilapho ukuthuthukisa ukusebenza kokudluliselwa kwenethiwekhi akuyona inhloso eyinhloko. Ngenxa yenani elilinganiselwe lamaklayenti ebhizinisini, amakhompyutha aphathekayo anokuhamba okuqinile. Emsebenzini wansuku zonke, abaphathi ngokuvamile badinga ukuhambisa amakhompyutha aphathekayo baye emagumbini okuhlangana ukuze bahlangabezane nezidingo zomsebenzi weselula. Kulokhu, imodi yokuhlukanisa ye-VLAN esekelwe emachwebeni ayifanele ibhizinisi, futhi indlela yokuhlukanisa i-VLAN efaneleke kakhulu isekelwe kumakheli e-MAC.
Ngakho-ke kumabhizinisi, imodi yokuhlukanisa i-VLAN efaneleke kakhulu isuselwe ekuhlukaniseni imbobo nokuhlukaniswa kwekheli le-MAC. Kumanethiwekhi ebhizinisi anenani elincane lamakhasimende nesidingo esivamile somsebenzi weselula, ukuhlukanisa ama-VLAN ngokusekelwe kumakheli e-MAC kuyindlela engcono kakhulu yokuhlukanisa. Kumanethiwekhi ebhizinisi anenani elikhulu lamakhasimende futhi asikho isidingo sehhovisi eliphathwayo, ama-VLAN angahlukaniswa ngokusekelwe kumachweba. Kafushane, khetha imodi yokuhlukanisa ye-VLAN efanelekile ngokusekelwe ezidingweni zenethiwekhi.
Isiphetho:
Ukuhlukanisa ama-VLAN kubonakala kuyisihloko esivamile, kodwa ekusebenzeni okungokoqobo, bambalwa abantu abakwazile ukusebenzisa kahle ukwahlukanisa kwe-VLAN njengethuluzi lokuphatha. Okubaluleke nakakhulu, amanye amanethiwekhi awadingi ukuhlukaniswa kwe-VLAN, kodwa ngenxa yalokho, abasebenzi bezobuchwepheshe bahlukanisela ama-VLAN, okuholela ekunciphiseni ukusebenza kahle kwenethiwekhi. Kuncane okwaziwayo ukuthi ukwahlukanisa okunengqondo kwe-VLAN kungathuthukisa ukusebenza kahle kokudluliselwa kwenethiwekhi, ingasaphathwa eyokucabangela ukwahlukanisa kwe-VLAN njengesixazululo esihle sokunciphisa isivinini senethiwekhi.
