Cov neeg siv koom nrog tib VLAN ntawm lub network nyob yuav txuas nrog cov hloov pauv sib txawv, thiab tej zaum yuav muaj ntau dua ib VLAN hla qhov hloov. Txhawm rau sib txuas lus nrog cov neeg siv, kev sib txuas ntawm cov keyboards yuav tsum muaj peev xwm txheeb xyuas thiab xa cov ntaub ntawv ntawm ntau vlans tib lub sijhawm. Raws li cov khoom sib txuas sib txuas thiab kev ua tiav ntawm xa thiab tau txais cov ntaub ntawv thav ntawv, muaj ntau hom kev sib txuas ntawm vlans hloov mus rau kev sib txuas sib txawv thiab kev sib txuas.
Cov neeg muag khoom sib txawv txhais cov VLAN interface hom sib txawv. Huawei pab kiag li lawm siv peb hom VLAN interface: Nkag mus, Lub cev, thiab Hybrid.
Nkag mus interface
Access interface feem ntau yog siv los txuas rau cov neeg siv khoom siv (xws li cov neeg siv tswv thiab cov servers) uas tsis paub cov cim npe, lossis tsis tas yuav cais VLAN cov tswv cuab.
Hauv VLAN hloov chaw, Ethernet cov ntaub ntawv thav ntawv tuaj nyob rau hauv ob daim ntawv hauv qab no:
Untagged thav duab: Thawj thav duab tsis muaj 4-byte VLAN lossis.
Tagged ncej: Ib tug ncej ntxiv rau 4-byte VLAN tag.
Feem ntau, Access interface tuaj yeem xa thiab txais tsuas yog Untagged thav duab, thiab tuaj yeem ntxiv qhov cim VLAN Tag rau tsuas yog Untagged thav duab. Cov txheej txheem hloov tsuas yog Tagged ntas. Yog li ntawd, Access interface yuav tsum tau ntxiv VLAN cim npe rau cov thav ntawv tau txais, thiab lub neej ntawd VLAN yuav tsum tau teeb tsa. Tom qab lub neej ntawd VLAN raug teeb tsa, Access interface ntxiv rau VLAN.
Thaum Access interface tau txais ib lub thav duab nrog Tag thiab cov ncej muaj tib VID thiab PVID, Access interface kuj tuaj yeem tau txais thiab ua cov ncej.
Ua ntej xa tus ncej nrog Tag, Access interface strips Tag..
Lub cev interface
Lub cev sib txuas yog siv los txuas cov keyboards, routers, aps, thiab lub suab terminals uas tuaj yeem xa thiab tau txais Tagged thiab Untagged ntas tib lub sijhawm. Nws tso cai rau thav ntawv ntawm ntau vlans kom dhau nrog cov cim npe, tab sis tsuas yog cov thav ntawv uas koom nrog lub neej ntawd VLAN raug tso cai xa tawm los ntawm qhov kev sib txuas no yam tsis muaj cim npe (uas yog, cov cim raug tshem tawm).
Lub neej ntawd VLAN ntawm lub Trunk interface kuj txhais tau tias yog haiv neeg VLAN los ntawm qee tus neeg muag khoom. Thaum Lub Cev Lub Cev tau txais ib qho Untagged thav duab, nws ntxiv ib Daim Ntawv Sib Txuas rau Native VLAN rau tus ncej.
Hybrid interface
Hybrid ports tuaj yeem siv los txuas cov neeg siv khoom siv (xws li cov neeg siv tswv thiab servers) thiab cov khoom siv hauv network (xws li hubs) uas tsis tuaj yeem paub cov cim npe, hloov pauv, routers, thiab lub suab terminals thiab aps uas tuaj yeem xa thiab tau txais Tagged thiab Untagged ntas ntawm tib lub sijhawm. Nws tso cai rau thav ntawv nrog cov cim npe ntawm ntau vlans kom dhau mus thiab tso cai rau cov thav ntawv xa los ntawm qhov kev sib txuas no los nqa cov cim npe ntawm qee qhov vlans (uas yog, thav ntawv tsis muaj cim npe) thiab thav ntawv tsis muaj cov cim npe ntawm qee qhov vlans (uas yog, thav ntawv tsis muaj cim npe) raws li xav tau.
Hybrid interfaces thiab Trunk interfaces yuav siv tau nyob rau hauv ntau daim ntawv thov scenarios, tab sis Hybrid interfaces yuav tsum tau siv nyob rau hauv tej daim ntawv thov scenarios. Piv txwv li, hauv QinQ hloov tau, pob ntawv los ntawm ntau lub vlans ntawm tus neeg muab kev pabcuam lub network yuav tsum tau rub tawm cov ntawv VLAN sab nraud ua ntej nkag mus rau tus neeg siv lub network. Nyob rau hauv cov ntaub ntawv no, Lub Cev interface tsis tuaj yeem ua qhov haujlwm no, vim tias Lub Cev interface tsuas tuaj yeem tso cov pob ntawv los ntawm lub neej ntawd VLAN ntawm lub interface kom dhau yam tsis muaj VLAN cim npe.
Cov saum toj no yogHDVPhoxov tooj cua Technology Ltd. coj cov neeg siv khoom txog "hloov ntawm qhov cuam tshuam cuam tshuam" kab lus qhia, thiab peb lub tuam txhab yog cov chaw tsim khoom tshwj xeeb ntawm optical network manufacturers, cov khoom lag luam koom nrog tsis tsuas yog transceiver series, ntau ONU series, optical module series, OLT series, thiab lwm yam. ., muaj ntau yam specifications ntawm cov khoom rau txawv scene xav tau kev pab txhawb nqa network, txais tos nug.
