ʻO VLAN (Virtual Local Area Network) kahi ʻenehana kamaʻilio e hoʻokaʻawale pono i kahi LAN kino i nā kikowaena hoʻolaha lehulehu. ʻO kēlā me kēia VLAN kahi kahua hoʻolaha kahi e hiki ai i nā mea hoʻokipa ke kamaʻilio pololei, ʻoiai ua kaupalena ʻia ke kamaʻilio ʻana ma waena o nā VLAN like ʻole. ʻO ka hopena, ua kaupalena ʻia nā leka hoʻolaha i hoʻokahi VLAN.
VLAN | Uena lalo |

ʻokoʻa | Hoʻohana ʻia e hoʻokaʻawale i nā pūnaewele Layer 2. |
Ma hope o ka hoʻonohonoho ʻana i nā loulou VLAN, hiki i nā mea hoʻohana i nā VLAN ʻokoʻa ke kamaʻilio wale inā hoʻokumu ʻia ke alahele. | |
Hiki ke wehewehe ʻia a hiki i 4094 VLAN; ʻAʻole kaupalena ka helu o nā mea hana i loko o kahi VLAN. | |
Pilina | I loko o ka VLAN hoʻokahi, hiki ke wehewehe i hoʻokahi a ʻoi aku paha nā subnets. |
ʻO ke kahua VID i loko o ke kiʻi ʻikepili e ʻike i ka VLAN nona ka ʻikepili; hiki ke hoʻouna wale ʻia ka ʻikepili i loko o kāna VLAN i koho ʻia. ʻO ke kahua VID e hōʻike ana i ka VLAN ID, hiki ke loaʻa mai ka 0 a hiki i 4095. No ka mea ua mālama ʻia ka 0 a me 4095 e ka protocol, ʻo ka palena kūpono no nā VLAN ID ʻo 1 a 4094. ʻO nā papa ʻikepili āpau i hana ʻia i loko e ka hoʻololi e lawe i nā hōʻailona VLAN, ʻoiai ʻO kekahi mau mea hana (e like me nā mea hoʻohana a me nā kikowaena) i hoʻopili ʻia i ka hoʻololi e hoʻouna wale a loaʻa i nā kiʻi Ethernet kuʻuna me ka ʻole o nā hōʻailona VLAN.
No laila, no ka launa pū ʻana me kēia mau hāmeʻa, pono e ʻike nā mea hoʻololi i nā papa Ethernet kuʻuna a hoʻohui a wehe paha i nā huaʻōlelo VLAN i ka wā o ka lawe ʻana. ʻO ka hōʻailona VLAN i hoʻohui ʻia e pili ana i ka VLAN paʻamau (Port Default VLAN ID, PVID).
