Hauv cov tes hauj lwm niaj hnub no, kev ua tau zoo thiab kev ruaj ntseg yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj ntau yam khoom siv thiab cov neeg siv sib koom tib lub network. Nov yog qhov uas VLANs (Virtual Local Area Networks) tuaj ua si. VLANs yog cov cuab yeej muaj zog uas, thaum ua ke nrog cov keyboards, tuaj yeem hloov pauv kev tswj hwm network thiab koom haum. Tab sis dab tsi yog VLAN? Nws ua haujlwm li cas nrog cov keyboards? Cia peb tshawb nrhiav.
VLAN yog dab tsi?
VLAN yog ib qho kev faib ua virtual ntawm lub cev lub cev. Ntau dua li muaj txhua yam khoom siv sib txuas lus ywj pheej ntawm tib lub network, VLANs tso cai rau koj los tsim cov kev sib txuas virtual nyob hauv tib lub cev. Txhua VLAN ua haujlwm raws li qhov chaw ywj pheej, yog li ua kom muaj kev ruaj ntseg, txo cov kev sib tsoo, thiab txhim kho kev ua haujlwm hauv network tag nrho.
Piv txwv li, hauv chaw ua haujlwm, koj tuaj yeem siv VLANs los faib lub network:
Departments: Kev Lag Luam, Nyiaj Txiag, thiab IT tuaj yeem muaj lawv tus kheej VLANs.
Ntaus Ntaus: Sib cais network rau khoos phis tawj, IP xov tooj, thiab lub koob yees duab kev ruaj ntseg.
Qib Kev Ruaj Ntseg: Tsim VLANs rau pej xeem cov qhua nkag thiab cov txheej txheem sab hauv ntiag tug.
VLANs ua haujlwm nrog cov keyboards li cas?
Cov keyboards ua lub luag haujlwm tseem ceeb hauv kev ua kom VLANs. Yuav ua li cas lawv ua hauj lwm ua ke:
VLAN Configuration: Tswj keyboards txhawb VLAN configuration, qhov twg cov chaw nres nkoj tshwj xeeb raug xa mus rau VLANs tshwj xeeb. Qhov no txhais tau hais tias cov cuab yeej txuas nrog cov chaw nres nkoj tau dhau los ua ib feem ntawm VLAN ntawd.
Kev segmentation: VLANs cais kev khiav tsheb, kom ntseeg tau tias cov khoom siv hauv ib VLAN tsis tuaj yeem sib txuas lus ncaj qha nrog cov cuab yeej hauv lwm VLAN tshwj tsis yog tso cai los ntawm cov cai tswj hwm.
Tagged thiab untagged ports:
Untagged ports: Cov chaw nres nkoj no yog ib feem ntawm VLAN nkaus xwb thiab siv rau cov khoom siv uas tsis txhawb VLAN tagging.
Tagged chaw nres nkoj: Cov chaw nres nkoj no nqa tsheb khiav mus rau ntau lub VLANs thiab feem ntau yog siv los txuas cov keyboards lossis txuas cov keyboards rau routers.
Inter-VLAN Kev Sib Txuas Lus: Txawm hais tias VLANs raug cais los ntawm lub neej ntawd, kev sib txuas lus ntawm lawv tuaj yeem ua tiav siv Layer 3 hloov lossis router.
Cov txiaj ntsig ntawm kev siv VLANs
Txhim kho kev ruaj ntseg: Los ntawm kev cais cov ntaub ntawv rhiab thiab cov khoom siv, VLANs txo qhov kev pheej hmoo ntawm kev nkag tsis tau.
Txhim kho kev ua tau zoo: VLANs txo qis kev tshaj tawm xov xwm thiab txhim kho kev ua haujlwm hauv network.
Kev tswj kom yooj yim: VLANs tso cai rau lub koom haum zoo dua ntawm cov khoom siv thiab cov neeg siv, ua rau kev tswj xyuas network yooj yim dua.
Scalability: Raws li koj txoj kev lag luam loj hlob, VLANs ua kom yooj yim ntxiv thiab faib cov cuab yeej tshiab yam tsis tas yuav hloov kho tag nrho lub cev network.
Kev siv VLAN hauv qhov tseeb scenarios
Kev Lag Luam: Muab cais VLANs rau cov neeg ua haujlwm, cov qhua, thiab IoT cov khoom siv.
Tsev Kawm Ntawv: Muab VLANs rau cov kws qhia ntawv, cov tub ntxhais kawm, thiab kev tswj hwm.
Tsev Kho Mob: Muab VLANs ruaj ntseg rau cov ntaub ntawv tus neeg mob, khoom siv kho mob, thiab pej xeem Wi-Fi.
Txoj kev ntse dua los tswj koj lub network
VLANs, thaum siv nrog tswj cov keyboards, muab cov kev daws teeb meem muaj zog rau kev tsim kom muaj txiaj ntsig zoo, ruaj ntseg, thiab muaj peev xwm loj tau. Txawm hais tias koj tab tom teeb tsa kev lag luam me lossis tswj hwm kev lag luam loj, kev siv VLANs tuaj yeem ua kom yooj yim rau kev tswj hwm network thiab txhim kho kev ua haujlwm tag nrho.
