Shamwari yakataura nzira yekugovera vlans, asi kutaura zvazviri, kugovera vlans kwakakosha mumashandisirwo etekinoroji. Mazhinji network anoda vlan partitioning. Nhasi, ngatidzidzei nezvechinhu ichi pamwe chete.
Tsanangudzo yeVLAN:
VLAN ndicho chipfupiso cheVirtual Local Area Network muChirungu, inozivikanwawo seyakajairika yenzvimbo network. Iyo tekinoroji inoziva chaiwo mapoka ebasa nekugovanisa zvine musoro mukati metiweki yenzvimbo yenzvimbo muzvikamu zvetiweki pane kuzvipatsanura. Kuti ugovane maVLAN, unofanirwa kutenga zvishandiso zvetiweki zvinotsigira kushanda kweVLAN.
Chinangwa chekuparadzanisa VLANs:
VLAN inokurudzirwa kugadzirisa nyaya dzekutepfenyura uye kuchengetedzeka kweEthernet, uye kutepfenyura uye unicast traffic mukati meVLAN imwe haizoendeswa kune mamwe maVLAN. Kunyangwe kana makomputa maviri ari muchikamu chimwe chete chetiweki asiri muVLAN imwechete, nzizi dzawo dzekutepfenyura hadziendeswe kune imwe neimwe.
Kupatsanura maVLAN kunobatsira kudzora traffic, kuderedza mari yekushandisa, kurerutsa manejimendi manejimendi, uye kugadzirisa network kuchengetedza. Nekuda kwemaVLAN ekutsaura madutu ekutepfenyura uye kutaurirana pakati peVLAN dzakasiyana, kutaurirana pakati peVLAN dzakasiyana kunofanirwa kuvimba nema routers kana matatu-layer switch.
VLAN partitioning nzira:
Pane nzira ina dzekugovera maVLAN, imwe neimwe iine zvayakanakira nezvayakaipira. Kana uchipatsanura maVLAN kuita network, zvinodikanwa kuti usarudze nzira yakakodzera yekugovera zvinoenderana nemamiriro chaiwo etiweki.
1. VLAN yakavakirwa pachikamu chechiteshi: Vazhinji vanogadzira network vanoshandisa switch ports kuti vagovane nhengo dzeVLAN. Sezvinoratidzwa nezita racho, port based VLAN partitioning inoreva kutsanangura mamwe madoko ekuchinja seVLAN.
VLAN partitioning yakavakirwa pamadoko ndiyo inonyanya kushandiswa nzira yeVLAN yekugovera. Zvakanakira kupatsanura maVLAN zvichibva pazviteshi zviri nyore uye zvakajeka, uye manejimendi zvakare iri nyore kwazvo. Izvo zvisingabatsiri ndezvokuti kuchengetedza kunonetsa.
2. VLAN division yakavakirwa paMAC kero: Imwe neimwe network kadhi ine yakasarudzika kero pasi rose, inova kero yeMAC. Zvichienderana nekero yeMAC yetiweki kadhi, makomputa akati wandei anogona kukamurwa kuita imwechete VLAN.
Kubatsira kukuru kweiyi nzira ndeyekuti kana nzvimbo yemushandisi inofamba, ndiko kuti, kana uchichinja kubva kune imwe switch kuenda kune imwe switch, iyo VLAN haidi kugadziridzwa zvakare; Izvo zvakashata ndezvekuti kana uchitanga VLAN, vashandisi vese vanofanirwa kuigadzira, uye mutoro kune vashandisi unorema.
3. Gurai maVLAN zvichienderana netiweki layer: Iyi nzira yekukamura maVLAN yakavakirwa pane network layer kero kana protocol rudzi rwega rega rega, pane routing. Ongorora: Iyi VLAN partitioning nzira yakakodzera kune yakafara nzvimbo network uye haidi nharaunda nharaunda network.
4. VLAN classification yakavakirwa paIP multicast: IP multicast ndiyo tsanangudzo yeVLAN, zvinoreva kuti boka re multicast iVLAN. Iyi nzira yekuparadzanisa inowedzera maVLAN kune yakafara nzvimbo network uye haina kukodzera kunetiweki yenzvimbo, sezvo chiyero chemabhizinesi network hachisati chasvika pachiyero chakakura kudaro.
Zviripachena kuti ese VLAN matekinoroji haana kunyatsokodzera kushandiswa kwetiweki. Mushure mekuwana nzwisiso yakazara yeVLANs, isu tinofanirwa kukwanisa kuita mutongo wakajeka wekuti VLAN partitioning yakakosha zvichienderana netiweki nharaunda yedu.
Sarudza yakakodzera VLAN partitioning mode
Vazhinji vashandi vehunyanzvi vanongoziva chete kuti VLAN partitioning inogona kuvandudza network transmission performance, asi havazive kuti isina musoro VLAN partitioning mode inoderedza network kutapurirana kuita. Nekuda kwenzvimbo dzakasiyana dzematiweki akasiyana-siyana, iyo yakanyatsokodzera VLAN yekugovera nzira yekushandisa kwavo yakasiyanawo. Pazasi, isu ticha tsanangura kuti ndeipi VLAN partitioning mode inonzwisisika kune bhizinesi network uchishandisa mienzaniso.
Semuyenzaniso, mune network yemakambani, kune makumi mana nematatu emakomputa evatengi, ayo makumi matatu neshanu ari edesktop komputa uye 8 ari malaptop. Iyo traffic network haina kunyanyokurisa. Nekuda kweimwe data yakadzikama mudhipatimendi rezvemari iyo vashandiwo zvavo vasingade kuona, kuitira kuvandudza kuchengetedzeka kwenetiweki, manejimendi manejimendi afunga kupatsanura network kuita maVLAN kuparadzanisa kutaurirana pakati pevashandiwo zvavo uye maPC evashandi vedhipatimendi rezvemari.
Zvido zvekushandisa: Kubva pane tsananguro iri pamusoro, zvinogona kuoneka kuti bhizinesi rinopatsanura maVLAN kuvandudza kuchengetedzeka, nepo kuvandudza mashandiro ekutapurirana kwetiweki hachisi chinangwa chikuru. Nekuda kwehuwandu hushoma hwevatengi mubhizinesi, malaptop ane simba rekufamba. Mubasa remazuva ese, mamaneja anowanzo kuda kufambisa malaptop kumakamuri ekusangana kuti asangane nebasa renharembozha. Muchiitiko ichi, VLAN partitioning mode yakavakirwa pamadoko haina kukodzera bhizinesi, uye iyo yakanyatsokodzera VLAN partitioning nzira yakavakirwa pamakero eMAC.
Saka kumabhizinesi, iyo yakanyanya kukodzera VLAN yekugovera modhi yakavakirwa pachiteshi chekugovera uye MAC kero yekugovera. Kune mabhizinesi network ane nhamba diki yevatengi uye kazhinji kudiwa kwebasa renhare, kupatsanura maVLAN zvichienderana neMAC kero ndiyo yakanakisa yekugovera maitiro. Kune mabhizinesi network ane nhamba huru yevatengi uye pasina kudikanwa kwehofisi yenhare, maVLAN anogona kukamurwa zvichienderana nemadoko. Muchidimbu, sarudza yakakodzera VLAN partitioning mode zvichienderana netiweki zvinodiwa.
Mhedziso:
Kupatsanura maVLAN kunoratidzika sechinyorwa chenyaya, asi mune zvinoshanda, vanhu vashoma vakakwanisa kushandisa zvakanaka VLAN yekugovera sechishandiso chekutungamira. Zvinotonyanya kukosha, mamwe manetwork haadi VLAN partitioning, asi semhedzisiro, vashandi vehunyanzvi vanopatsanura maVLAN kwavari, zvichikonzera kuderedzwa kwetiweki kutaurirana. Zvishoma zvinozivikanwa kuti zvine musoro VLAN partitioning inogona kuvandudza network kutapurirana zvakanaka, rega kufunga nezveVLAN partitioning semhinduro yakanaka yekunonoka network kumhanya.
