VLAN (Virtual Local Area Network) imatchedwa "Virtual LAN" mu Chitchaina.
VLAN imagawanitsa LAN yakuthupi kukhala LAN yambiri yomveka, ndipo VLAN iliyonse ndi malo owulutsa.Magulu a VLAN amatha kuyanjana ndi mauthenga kudzera mukulankhulana kwachikhalidwe cha Efaneti, pamene ngati makamu mu VLAN yosiyana akufunikira kulankhulana, ziyenera kukwaniritsidwa kudzera pazida zosanjikiza maukonde monga rauta. kapena kusintha kwa magawo atatu.
Zotsatirazi zikufotokozera lamulo la Vlan lokhazikika padoko:
Doko la Access likhoza kukhala la VLAN imodzi, kotero VLAN yake yosasinthika ndi VLAN komwe ili, palibe chifukwa chokhazikitsa;madoko a Hybrid ndi Trunk madoko amatha kukhala a VLAN angapo, chifukwa chake khazikitsani ID ya VLAN ya doko.
1. Doko lolowera: landirani uthenga womwe walandilidwa popanda tag ndikuwonjezera Tag yokhazikika ku uthengawo.Mukalandira uthenga wokhala ndi Tag, ① ikalandira ID ya VLAN imakhala yofanana ndi ID yokhazikika ya VLAN.Ngati uthengawo utatayidwa pamene VLAN ID yatumizidwa, Tag imachotsedwa.
2. Thumba la thunthu: Pamene uthenga walandiridwa popanda Tag, doko litawonjezedwa kale ku VLAN yosasinthika, Phatikizani Tag ya VLAN yosasinthika ya uthengawo ndikuyitumiza, Pamene doko siligwirizana ndi VLAN yosasinthika, Tayani. uthenga;Pamene uthenga wolandira umanyamula Tag, Pamene ID ya VLAN ndi ID ya VLAN yololedwa kupyolera ndi doko ili, Kulandira uthenga, Pamene ID ya VLAN si VLAN ID yololedwa ndi doko limenelo, Tayani uthengawo;Mukatumiza uthenga, Pamene ID ya VLAN ili yofanana ndi ID yosasinthika ya VLAN, chotsani Tag, Tumizani uthenga uwu pamene ID ya VLAN ili yosiyana ndi ID ya VLAN yosasinthika, Kusunga Tag yoyambirira, Tumizani uthengawo.
3. Doko la Hybrid: Ntchito mukalandira uthenga ndi yofanana ndi ya Trunk port.Mukatumiza uthenga, ID ya VLAN yonyamula mu uthengawo ndi ID ya VLAN yololedwa padoko, ndipo doko limatha kukonza ngati kunyamula Tag potumiza uthenga wa VLAN (kuphatikiza VLAN yosasintha).
Chithunzi chotsatira ndi HDV 8pon port epon olt yathu:
Yathu HDV 8pon port epon olt kukonza lamulo losakhazikika la vlan padoko ndi: port default-vlan 100.
Lamulo lowonjezera doko ku vlan logwirizana ndilo: vlan hybrid 100 untagged.Mungathe kusintha wosakanizidwa kuti mufike ndi thunthu, ndipo osatchulidwa akhoza kusinthidwa kukhala otchulidwa, malingana ndi zomwe mukufuna.
