Qodobka ugu caansan ee maanta loo isticmaalo in lagu taageero VLANs waa IEEE 802.1Q. Kooxda shaqada ee IEEE 802.1 waxay qeexeen habkan loo adeegsado VLANs isku dhafan si ay u bixiyaan taageerada VLAN ee alaab-qeybiyeyaasha badan. Ka hor inta aan la soo bandhigin heerka 802.1Q, dhowr borotokool oo lahaansho leh ayaa jiray, sida Cisco Inter-Switch Link (ISL) iyo 3Com's Virtual LAN Trunk (VLT). Cisco ayaa sidoo kale hirgelisay VLANs FDDI iyadoo ku xiran macluumaadka VLAN ee madaxa IEEE 802.10 frame, taas oo ka soo horjeedda ujeedada heerka IEEE 802.10. Su'aal: Maxay yihiin hababka loo adeegsaday ka hor heerka 802.1Q?
