Isticmaalayaasha ka tirsan isla VLAN ee shabakada tooska ah ayaa laga yaabaa inay ku xidhmaan furayaasha kala duwan, waxaana laga yaabaa inay jiraan wax ka badan hal VLAN guud ahaan dareemada. Si loola xidhiidho isticmaalayaasha, is-dhexyada u dhexeeya furayaasha waa inay awoodaan inay aqoonsadaan oo ay soo diraan xayndaabka xogta vlans badan isku mar. Marka loo eego shayga isku xidhka interfiyuuga iyo habaynta xadhkaha xogta ee la soo diray iyo kuwa la helay, waxa jira noocyo badan oo interfiyuuga oo vlan ah si ay ula qabsadaan isku xidhka kala duwan iyo isku xidhka
Iibiyeyaal kala duwan ayaa si kala duwan u qeexaya nooca Interface VLAN. Aaladaha Huawei waxay isticmaalaan saddex nooc oo VLAN interface caadi ah: Helitaanka, Jirka, iyo Hybrid.
Interface galitaanka
Interface-ka Helitaanka guud ahaan waxaa loo isticmaalaa in lagu xidho meelaha isticmaalaha (sida adeegsadaha iyo adeegayaasha) kuwaas oo aan aqoonsanayn calaamadaha, ama aan u baahnayn in la kala saaro xubnaha VLAN.
Shabakadda beddelka VLAN, xarfaha xogta Ethernet waxay ku yimaadaan labada qaab ee soo socda:
Jirka aan la taaban: Qaabka asalka ah oo aan lahayn summada 4-byte VLAN.
Tagged frame: Fareem lagu daray sumadda 4-byte VLAN.
Inta badan, Interface-ka Access waxa uu soo diri karaa oo heli karaa kaliya fareemooyinka aan la tagin, oo waxa uu ku dari karaa VLAN Tag gaar ah oo kaliya fareemooyinka aan la taaban. Beddelka wuxuu ku shaqeeyaa kaliya Tagged frames. Sidaa darteed, interface-ka Helitaanka wuxuu u baahan yahay inuu ku daro calaamadaha VLAN-ga ee la helay, iyo VLAN-ga caadiga ah waa in la habeeyaa. Ka dib markii VLAN-ga caadiga ah la habeeyo, Interface-ka Access ayaa lagu daraa VLAN.
Marka Interface-ka Helitaanka uu helo fareem leh Tag oo jirku ka kooban yahay isla VID iyo PVID, Interface-ka Access waxa kale oo uu heli karaa oo farsamayn karaa qaabka.
Kahor intaadan dirin fareem leh Tag, Interface Interface ayaa xariijisa Tag.
Interface jir
Xirmooyinka jirridda waxaa loo isticmaalaa in lagu xiro furayaasha, router-yada, aps-ka, iyo terminaalka codka kuwaas oo diri kara oo heli kara Tagged and Untagged frames isku mar. Waxay u ogolaataa fireemooyinka vlans badan inay ku gudbaan calaamadaha, laakiin kaliya xirmooyinka ka tirsan VLAN-ga caadiga ah ayaa loo oggol yahay in laga soo diro interface-ka iyada oo aan lahayn calaamado (taas oo ah, tagsyada waa la saaray).
VLAN-ga caadiga ah ee ku yaal interface Trunk waxaa sidoo kale lagu qeexay VLAN-ga hooyo ee iibiyaasha qaarkood. Marka interface jirku helo jir aan la taaban, wuxuu ku darayaa Tag u dhiganta VLAN-ga Dhaladka ah jirku.
Isku-dhafka isku-dhafka ah
Dekadaha isku-dhafka ah waxaa loo isticmaali karaa in lagu xiro terminaalka isticmaalaha (sida adeegsadaha martida loo yahay iyo server-yada) iyo aaladaha shabakadaha (sida hubsyada) ee aan aqoonsan karin tags, furayaasha, router-yada, iyo terminaalka codka iyo aps-ka soo diri kara oo heli kara Tagged iyo fareemooyinka aan la taaban karin isku mar. Waxay u ogolaataa fireemooyinka leh summada vlans badan inay dhex maraan waxayna u ogolaataa fireemooyinka laga soo diray interface-kan inay qaadaan calaamadaha vlans gaar ah (taas oo ah, xargaha aan lahayn tags) iyo fareemooyinka aan lahayn calaamadaha vlans qaarkood (taas oo ah, xargaha aan lahayn tags) sida loo baahan yahay.
Isku-xidhka isku-dhafka ah iyo is-dhex-galka jirridda waxaa loo isticmaali karaa xaalado badan oo codsi ah, laakiin is-dhexgalyada isku-dhafan waa in loo adeegsadaa xaaladaha codsiyada qaarkood. Tusaale ahaan, QinQ dabacsan, baakado ka yimid vlans badan oo ku yaal shabakadda adeeg bixiyaha waxay u baahan yihiin inay ka xayuubiyaan summada VLAN-ka ee bannaanka ka hor inta aanad gelin shabakadda isticmaalaha. Xaaladdan oo kale, interface-ka Trunk ma qaban karo shaqadan, sababtoo ah interface-ka jirku wuxuu u oggolaan karaa oo kaliya baakadaha VLAN-ga caadiga ah ee interface-ka inay dhaafaan iyada oo aan lahayn calaamadaha VLAN.
