Dhammaanteen waan ognahay in isla LAN-ka, isku xirka hubku uu abuuri doono goob colaadeed.Marka la beddelo, barta isku dhaca waa la xallin karaa, waxaa jiri doona qayb baahineed.Si loo xalliyo domainkan baahinta, waxaa lagama maarmaan ah in la soo bandhigo router si ay u kala qaybiyaan LAN-yada kala duwan ee qaybaha warbaahineed ee kala duwan si loo yareeyo faragelinta domainka ee u dhexeeya qalabka.Ma soo jeedin karnaa in furaha uu sidoo kale leeyahay shaqada routerkan?Horumarinta ka dib, fikradda VLAN ayaa la soo jeediyay.Waa maxay VLAN?
"VLAN" macnaheedu waa "Shabakadda Aagga Deegaanka Virtual."
Shabakad maxalli ah oo dalwad ah (VLAN) si macquul ah ayaa loo qaybiyaa qaybo badan oo warbaahin ah, goob kasta oo warbaahineedna waa VLAN.Sida loo qaybsado.
Jaantuskan soo socdaa waxa uu muujinayaa in dawiishku u qaybsan yahay LAN-yada casriga ah.Dhanka bidix, iyada oo loo marayo goobaha gudaha, beddelkaani wuxuu u qaybiyaa domainka baahinta saddex qaybood oo warbaahin ah, VLAN1, VLAN2, iyo VLAN3.Muuqaal ahaan, qalabkani waxa uu ku socdaa hal shid, laakiin caqli ahaan, waxa loo qaybiyay saddex shid, markaa waxa jiri doona saddex LAN (virtual LANs) iyo saddex domains.
Kala qaybintu waxay u beddeshaa LAN-yada casriga ah
Qaybta VLAN ee furaha waxay tilmaamaysaa in VLAN 1, lambarka VLAN, uu guud ahaan ka shaqeeyo kooxda maaraynta, markaa VLAN-yada caadiga ah waxaa lagu tiriyaa 2 ilaa 3. Sida caadiga ah, dhammaan VLAN-yada waxay leeyihiin VALN1.
Kor ku xusan waa sharaxaadda fikradda VLAN, ama LAN dalwaddii, oo ay keentay Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. Shenzhen HDV Phoelectron Technology Co., Ltd. waa soo saaraha ku takhasusay qalabka isgaarsiinta indhaha.
