VLAN (Virtual Local Area Network) imatchedwa "Virtual LAN" mu Chitchaina.
VLAN imagawa LAN yakuthupi kukhala ma LAN angapo omveka, ndipo VLAN iliyonse ndi malo owulutsa. Okhala mu VLAN amatha kulumikizana ndi mauthenga kudzera mumayendedwe achikhalidwe a Efaneti, koma pakati pa makamu mu VLAN yosiyana, kulumikizana kuyenera kuchitika kudzera pazida zosanjikiza maukonde mongarautakapena magawo atatukusintha.
Zotsatirazi zikufotokozera lamulo la Vlan lokhazikika padoko:
Kufikira, Doko likhoza kukhala la 1 VLAN, kotero VLAN yake yosasinthika ndi VLAN komwe ili, palibe seti; doko la Hybrid ndi doko la Trunk litha kukhala la VLAN zingapo, chifukwa chake muyenera kukhazikitsa ID ya VLAN ya doko.
1. Doko lolowera: Mukalandira uthenga wopanda tag, landirani uthengawo ndikuwonjezera chizindikiro cha VLAN ku uthengawo; Uthenga wolandiridwa ndi Tag, ① ukalandira uthengawo pamene ID ya VLAN ili yofanana ndi ID ya VLAN yosasinthika, taya uthengawo pamene VLAN ID ndi VLAN ID yokhazikika, kutumiza Tag popanda kuyika.
2. Thumba la thunthu: litalandira popanda Tag, Pamene doko lalowa kale VLAN yosasinthika, Phukusi ndi kutsogolo Tag kwa kusakhulupirika kwa uthenga ndi VLAN, Pamene doko siliphatikizapo VLAN yosasinthika, Tayani uthengawo; Pamene uthenga wolandiridwa umanyamula Tag, Pamene ID ya VLAN ndi ID ya VLAN yololedwa ndi doko ili, Kulandira uthenga, Pamene ID ya VLAN si VLAN ID yololedwa ndi doko limenelo, Tayani uthengawo; Uthengawo ukatumizidwa, Pamene ID ya VLAN ili yofanana ndi ID ya VLAN yosasinthika, 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 yolandila uthenga ndi yofanana ndi doko la Trunk. Mukatumiza uthenga, pomwe ID ya VLAN yonyamula uthengawo ndi ID ya VLAN yololedwa ndi doko, uthengawo utha kutumizidwa, ndipo doko likhoza kukhazikitsidwa kuti linyamule Tag potumiza uthenga wa VLAN (kuphatikiza VLAN yosasintha).
Chithunzi chotsatira ndi HDV 8pon pakamwa pa EPONOLT
EPON yathu ya HDV 8pon portOLTkukonza lamulo losakhazikika la vlan padoko ndi: port default-vlan 100.
Lamulo lowonjezera doko ku vlan lolingana ndi: vlan hybrid 100 untagged. Mutha kulowa m'malo osakanizidwa kuti mupeze ndikuyesa, ndipo osatchulidwa amatha kuyikidwa, kutengera zomwe mukufuna.
