Iyo VLAN (Virtual Local Area Network) inonzi "Virtual LAN" muchiChinese.
VLAN inokamura LAN yemuviri kuita LAN yakawanda inonzwisisika, uye VLAN yega yega inzvimbo yekutepfenyura.Vabati muVLAN vanogona kutaurirana nemharidzo kuburikidza neyakajairwa Ethernet kutaurirana, nepo kana mauto muVLAN akasiyana achida kutaurirana, inofanirwa kuwanikwa kuburikidza netiweki layer zvishandiso senge router. kana matatu-layer switch.
Izvi zvinotevera zvinotsanangura iyo port-based Vlan mutemo:
Iyo Access port inogona kungove yeVLAN imwe chete, saka iyo default VLAN ndiyo VLAN pairi, hapana chikonzero chekuisa;iyo Hybrid port uye Trunk ports inogona kuva yeVLAN yakawanda, saka isa iyo default VLAN ID yechiteshi.
1. Kusvika pachiteshi: gamuchira iyo yakagamuchirwa meseji isina tag uye wedzera iyo default Tag kune meseji.Kana iyo meseji yakagamuchirwa neTag, ① inogamuchira iyo VLAN ID yakafanana neiyo default VLAN ID.Kana meseji ikaraswa kana VLAN ID yatumirwa, iyo Tag inobviswa.
2. Trunk port: Kana iyo meseji yagamuchirwa isina Tag, Kana chiteshi chatowedzerwa kune yakasarudzika VLAN, Paka iyo Tag yeiyo default VLAN yemeseji uye woiendesa, Kana iyo chiteshi ikasabatana neiyo default VLAN, Rasa. the message;Kana iyo yakagamuchirwa meseji inotakura Tag, Kana iyo VLAN ID iri VLAN ID inotenderwa kuburikidza nechiteshi ichi, Kugamuchira meseji, Kana iyo VLAN ID isiri iyo VLAN ID inobvumirwa nechiteshi ichocho, Rasa meseji;Pakutumira meseji, Kana iyo VLAN ID yakafanana neiyo default VLAN ID, bvisa Tag, Tumira meseji iyi kana VLAN ID yasiyana neiyo default VLAN ID, Kuchengeta iyo yekutanga Tag, Tumira meseji.
3. Hybrid port: Kushanda kana uchigamuchira meseji kwakafanana neiyo yeTrunk port.Pakutumira meseji, iyo VLAN ID inotakurwa mumeseji ndiyo VLAN ID inotenderwa pachiteshi, uye chiteshi chinogona kugadzirisa kana kutakura Tag kana uchitumira meseji yeVLAN (kusanganisira iyo default VLAN).
Iyi inotevera nhamba ndeye yedu HDV 8pon port epon olt:
Yedu HDV 8pon port epon olt kugadzirisa iyo default vlan command muchiteshi ndeye: port default-vlan 100.
Murairo wekuwedzera chiteshi kune inoenderana vlan ndeiyi: vlan hybrid 100 untagged.Unogona kushandura hybrid kuti isvike uye trunk, uye isina kunyorwa inogona kuchinjwa kuti iite tagged, zvichienderana nezvinodiwa.
