VLAN (Shabakadda Deegaanka Virtual) waxa loogu magac daray "Virtual LAN" ee Shiinaha.
VLAN waxay u qaybisaa LAN jireed LAN badan oo macquul ah, VLAN kastana waa domain baahinta. Martigeliyayaasha VLAN waxay la falgali karaan farriimaha iyaga oo isticmaalaya isgaarsiin dhaqameed, halka haddii martigeliyayaasha VLAN kala duwan ay u baahan yihiin isgaarsiin, waa in lagu gaaraa iyada oo loo marayo qalabka lakabka shabakada sida.routerama saddex lakabbeddelo.
Waxa soo socda ayaa qeexaya xeerka Vlan ee ku salaysan dekedda:
Dekadda Access waxay yeelan kartaa oo keliya hal VLAN, markaa VLAN-keeda caadiga ah waa VLAN halka ay ku taal, looma baahna in la dejiyo; Dekedda Hybrid iyo dekedaha jirku waxay ka tirsan yihiin VLAN badan, markaa deji aqoonsiga VLAN ee dekedda.
1. Gelitaanka dekedda: hel fariinta la helay iyada oo aan calaamad lahayn oo ku dar calaamadda caadiga ah ee fariinta. Marka fariinta la helo ee Tag leh, ① helo aqoonsiga VLAN wuxuu la mid yahay aqoonsiga VLAN ee caadiga ah. Haddii fariinta la tuuro marka VLAN ID la diro, Tag waa la saarayaa.
2. Port Trunk: Marka fariinta la helo iyada oo aan Tag la'aan ahayn, Marka dekeddu horay loogu daro VLAN-ga caadiga ah, xidho Tag of the default VLAN ee fariinta oo u gudbi, Marka ay dekeddu ku biiri waydo VLAN-ga caadiga ah, iska tuur. fariinta; Marka fariinta la helay ay sido Tag, Marka VLAN ID uu yahay VLAN ID-ga loo ogol yahay in la soo maro dekeddu, Helitaanka fariinta, Marka VLAN ID ma aha VLAN ID ee dekeddaas u ogol yahay, tuur fariinta; Markaad direyso fariinta, Marka VLAN ID uu la mid yahay aqoonsiga VLAN ee caadiga ah, ka saar Tag, dir fariintan marka VLAN ID ka duwan yahay VLAN ID-ga caadiga ah, Haysashada Tag asalka ah, dir fariinta.
3. Deked isku-dhafan: Hawlgalka marka farriinta la helayo waxay la mid tahay ta dekedda jirridda. Marka fariinta la dirayo, aqoonsiga VLAN ee fariinta xambaarsan waa VLAN ID-ga loo ogol yahay dekeddu, dekedduna waxay habayn kartaa in ay sido Tag marka la dirayo fariinta VLAN (oo ay ku jiraan VLAN default).
Sawirka soo socdaa waa HDV 8pon port eponolt:
HDV 8pon dekedda eponoltSi loo habeeyo amarka caadiga ah ee vlan ee dekeddu waa: port default-vlan 100.
Amarka lagu daro dekedda vlan u dhigma waa: vlan hybrid 100 untagged. Waxaad bedeli kartaa hybrid si aad u hesho iyo jirridda, iyo untagged waxaa loo bedeli karaa sumad, ku xiran tahay baahida.
