Peb txhua tus paub tias ntawm tib LAN, kev sib txuas hub yuav tsim kom muaj kev sib cav sib ceg. Thaum nyob rau hauvhloov, qhov kev tsis sib haum xeeb tuaj yeem daws tau, yuav muaj kev tshaj tawm xov xwm. Txhawm rau daws qhov kev tshaj tawm xov xwm no, nws yog qhov yuav tsum tau ua kom paub cov routers los faib cov LANs sib txawv rau hauv kev tshaj tawm xov xwm sib txawv txhawm rau txo qis tshaj tawm xov xwm cuam tshuam ntawm cov khoom siv. Peb puas tuaj yeem hais tiashloovkuj muaj lub luag haujlwm ntawm qhov norouter? Tom qab kev txhim kho, lub tswv yim ntawm VLAN yog npaj. VLAN yog dab tsi?
"VLAN" txhais tau tias "Virtual Local Area Network."
Ib lub network hauv zos virtual (VLAN) tau muab faib ua ntau qhov tshaj tawm, thiab txhua qhov tshaj tawm xov xwm yog VLAN. Yuav faib li cas.
Daim duab hauv qab no qhia tau hais tiashloovmuab faib ua virtual LANs. Ntawm sab laug, los ntawm kev teeb tsa sab hauv, qhov nohloovfaib cov tshaj tawm tshaj tawm rau hauv peb qhov tshaj tawm, VLAN1, VLAN2, thiab VLAN3. Lub cev, cov khoom siv no nyob ntawm ib qhohloov, tab sis qhov tseeb, lawv tau muab faib ua peb qhov hloov pauv, yog li yuav muaj peb LANs (virtual LANs) thiab peb qhov tshaj tawm.
Partitioning hloov mus rau hauv virtual LANs
Kev faib tawm ntawm VLANhloovqhia tias VLAN 1, tus lej VLAN, feem ntau ua haujlwm hauv pawg tswj hwm, yog li cov VLANs feem ntau raug suav los ntawm 2 txog 3. Los ntawm lub neej ntawd, tag nrho VLANs yog VALN1.
Cov saum toj no yog cov lus piav qhia ntawm lub tswv yim ntawm VLAN, los yog virtual LAN, coj los ntawm Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. Lub Shenzhen HDV Phoelectron Technology Co., Ltd. yog cov chaw tsim khoom tshwj xeeb hauv cov khoom siv kho qhov muag sib txuas lus.
