Hauv cov chaw muaj ib puag ncig xws li cov xaim hluav taws xob thee, nrog rau cov ntaub ntawv coal thiab sensor ntawm cov ntaub ntawv muaj txiaj ntsig zoo rau kev txhim kho network kev ua haujlwm, kev ruaj ntseg thiab kev tswj hwm kev nyab xeeb.
Cov ntaub ntawv tsis tsim nyog tau txo, li kev txhim kho kev siv ntawm network bandwidth. Cov Txheej Txheem Ceev Txheej Txheem: Thaum cov teeb meem tuaj yeem txiav txim sai sai uas VLAN muaj teeb meem, txo lub sijhawm daws teeb meem. Raws li cov cuab yeej siv nyiaj npib ntxaij kev tsim kho, Vlans tshiab tuaj yeem yooj yim ntxiv rau hloov kho kom haum rau cov kev xav tau tshiab thiab khoom siv tshiab. Tom qab faib cov VLans, tseem muaj ib qho teeb meem ntxiv: txhua tus VLAN yuav yog ib ntu network, thiab network tswj cov neeg lis haujlwm ua haujlwm yooj yim thiab txij nkawm.
Qhov sib txawv ntawm kev nkag mus thiab cov pob tw ports
Kev nkag mus rau chaw nres nkoj tsuas muaj ib vlan muab raws li PVID

Tagged cov thav ntawv thav duab: Yog {= pvid, tau txais, lwm yam pov tseg rau cov thav duab untagged: txheej txheem li PVAN |

Qhov kev nco ncaj qha ncaj qha
Cov chaw nres nkoj nkag tau siv los txuas cov khoom siv davhlau ya nyob twg thiab muab kev nkag mus rau ib VLAN.
Cov pob tw ntoo ports yog siv los sib txuas hloov chaw thiab muab kev sib kis tau ntawm ntau tus vlans.
Hom: interface hom, nkag mus, pob tw
Tagged vlan: thaum tsim ib vlan, tsuas yog ntxiv cov VLAN NUMBER
