Static VLANs inonziwo port-based VLANs. Izvi ndezvekutsanangura kuti ndechipi chiteshi ndecheVLAN ID. Kubva padanho remuviri, unogona kutsanangura zvakananga kuti iyo yakaiswa LAN inoenderana nechiteshi zvakananga.
Kana iyo VLAN maneja pakutanga inogadzirisa hukama hunoenderana pakati pechinjaport uye VLAN ID, hukama hunoenderana hwakagadziriswa. Ndokunge, imwe chete inoenderana VLAN ID inogona kusetwa yekuwana chiteshi uye haigone kuchinjwa gare gare kunze kwekunge maneja agadzirisa.
Kana mudziyo wakabatana nechiteshi ichi, ungaziva sei kana iyo VLAN ID yemuiti inoenderana nechiteshi? Izvi zvinotemerwa zvinoenderana neiyo IP gadziriso. Isu tinoziva kuti VLAN yega yega ine subnet nhamba uye ndeipi chiteshi inoenderana nayo. Kana iyo IP kero inodiwa nemudziyo isingaenderane nenhamba ye subnet yeVLAN inoenderana nechiteshi, kubatana kunokundikana, uye mudziyo haugone kutaurirana kazhinji. Naizvozvo, pamusoro pekubatanidza kune chaiyo chiteshi, mudziyo unofanirwawo kupihwa IP kero yeVLAN network segment, kuitira kuti iwedzere kuVLAN. Kuti unzwisise izvi, zvakakosha kuti unzwisise kuti subnet ine IP uye subnet mask. Kazhinji, mabheti matatu ekupedzisira e subnet anoshandiswa pakuzivikanwa kwezita rekupedzisira.

Kupfupisa, isu tinofanirwa kugadzirisa iyo VLAN nemachiteshi chimwe nechimwe. Zvisinei, kana zvinopfuura zana zviteshi mumambure zvinoda kugadziriswa, basa rinoguma harigoni kupedzwa munguva pfupi. Uye kana iyo VLAN ID ichida kuchinjwa, inoda kugadziridzwa-izvi zviri pachena kuti hazvina kukodzera kune iyo network inoda kushandura iyo topology chimiro kazhinji.
Kuti ugadzirise matambudziko aya, pfungwa yeVLAN ine simba yakaunzwa. Chii chinonzi dynamic VLAN? Ngatinyatsoongororai.
2. Dynamic VLAN: Dynamic VLAN inogona kuchinja VLAN yechiteshi chero nguva maererano nekombiyuta yakabatana kune imwe neimwe. Izvi zvinogona kudzivirira mabasa ari pamusoro, akadai sekuchinja marongero. Dynamic VLANs inogona kukamurwa kuita zvikamu zvitatu:
(1) VLAN ine MAC kero
VLAN yakavakirwa paMAC kero inosarudza muridzi wechiteshi nekubvunza uye kurekodha kero yeMAC yekombuta network network kadhi yakabatana nechiteshi. Ngatiti kero yeMAC "B" yakaiswa seyeVLAN 10 nechinja, saka zvisinei kuti kombiyuta ine kero yeMAC "A" yakabatanidzwa kupi, chiteshi chacho chichagoverwa muVLAN 10. Kana kombiyuta yakabatana nechiteshi 1, port 1 ndeyeVLAN 10; apo kombiyuta yakabatana nechiteshi chechipiri, chiteshi chechipiri ndecheVLAN 10. Nzira yekuzivikanwa inongotarisa kero yeMAC, kwete chiteshi. Chiteshi chinozokamurwa kuita VLAN inoenderana sezvo kero yeMAC ichichinja.

Nekudaro, yeVLAN yakavakirwa paMAC kero, kero dzeMAC dzemakomputa ese akabatana dzinofanirwa kuongororwa nekupinzwa mukati panguva yekuseta. Uye kana komputa ikatsinhanisa kadhi retiweki, iwe uchiri kuda kushandura marongero nekuti iyo MAC kero inoenderana netiweki kadhi, iyo yakaenzana neiyo hardware ID yetiweki kadhi.
(2) VLAN yakavakirwa paIP
Subnet yakavakirwa VLAN inosarudza iyo VLAN yechiteshi kuburikidza neIP kero yekombuta yakabatana. Kusiyana neVLAN yakavakirwa paMAC kero, kunyangwe kero yeMAC yekombuta ikachinja nekuda kwekutsinhana kwemakadhi etiweki kana zvimwe zvikonzero, chero IP kero yayo ikaramba isina kuchinjwa, inogona kuramba ichijoinha iyo yekutanga VLAN.
Naizvozvo, kana zvichienzaniswa neVLANs yakavakirwa paMAC kero, zviri nyore kushandura network chimiro. IP kero ndiyo ruzivo rwechikamu chechitatu muOSI reference model, saka tinogona kunzwisisa kuti VLAN yakavakirwa pa subnet inzira yekuisa zvisungo zvekupinda muchikamu chechitatu cheOSI.
(3) VLAN yakavakirwa pavashandisi
.
Mushandisi-based VLAN inosarudza kuti VLAN chiteshi ndechepi zvinoenderana neazvino mushandisi wekupinda pakombuta yakabatana kune imwe neimwe port yechinja. Ruzivo rwekuzivisa mushandisi pano kazhinji mushandisi anopinzwa nekombuta inoshanda sisitimu, senge zita remushandisi rinoshandiswa muWindows domain. Ruzivo rwezita remushandisi nderweruzivo rwuri pamusoro pechikamu chechina cheOSI.
