Tashar Access tana iya zama na VLAN guda ɗaya kawai, don haka tsohuwar VLAN ɗinta ita ce VLAN ɗin da take ciki kuma baya buƙatar saitawa. Matakan tashar jiragen ruwa da tashoshin jiragen ruwa na Trunk na iya kasancewa na VLan fiye da ɗaya, don haka kuna buƙatar saita tsoffin ID na VLAN don tashoshin jiragen ruwa.
1, Shiga tashar jiragen ruwa: karbi fakitin ba tare da tag ba, kuma ƙara tsoho VLAN Tag don fakitin; Lokacin da fakitin da aka karɓa yana da Tag, ① lokacin da VLAN ID yayi daidai da tsohuwar VLAN ID, ana karɓar fakitin; ② lokacin da VLAN ID ya bambanta da tsohon VLAN ID, ana zubar da fakitin; Lokacin aika fakitin, VLAN ID shine tsohuwar VLAN ID, don haka ba ya buƙatar saita shi, kuma ana aika shi bayan cire Tag.
2. Tashar jirgin ruwa: idan fakitin da aka karɓa ba shi da Tag, lokacin da tashar jiragen ruwa ta shiga tsohuwar VLAN, ana sanya Tag na tsoho VLAN don fakitin kuma a tura shi, lokacin da tashar jiragen ruwa ba ta shiga tsohuwar VLAN ba, fakitin. ana jefar da shi; Lokacin da fakitin da aka karɓa yana da Tag, za a karɓi fakitin idan VLAN ID shine ID na VLAN da aka yarda da shi na tashar jiragen ruwa. Lokacin da VLAN ID ba shine izinin VLAN ID na tashar jiragen ruwa ba, za a jefar da fakitin. Lokacin aika fakitin, lokacin da VLAN ID yayi daidai da tsohon VLAN ID, cire Tag ɗin kuma aika fakitin. Lokacin da VLAN ID ya bambanta da tsohon VLAN ID, ajiye ainihin Tag kuma aika fakitin.
3. Hybrid port: Aikin lokacin karbar fakiti daidai yake da aikin tashar jirgin ruwa. Lokacin aika fakiti, lokacin da VLAN ID ɗin da ke cikin fakitin shine VLAN ID ɗin da tashar tashar ta ba da izini, ana aika fakitin, kuma zaku iya saita ko tashar tana ɗaukar Tag lokacin aika fakitin VLAN (ciki har da tsoho VLAN) ta hanyar umarnin.
