I-LAN inowanikwa (Local Area Network) inonzwisisika inowanika pasi iyo inogona kuunganidza pamwe chete kuunganidza zvishandiso kubva kuLAN dzakasiyana-siyana. Makambani makuru emakombiyuta emakombiyuta anowanzogadzira VLANs kuti vadzokezve ruwavo rwavo kuti vawedzere kugadziriswa kwemigwagwa.
Mhando dzinoverengeka dzakasiyana-siyana dzehutano hwepanyama dzinotsigira vese LANs kusanganisira zvose Ethernet uye Wi-Fi .
Kubatsirwa kweVLAN
Kana yakagadzirirwa zvakanaka, maLAN anokwanisa kuvandudza kushanda kwematokari akawandisa. VLANs inotarisirwa kuunganidza pamwe chete maklayiti ekushandisa anotaurirana nguva nenguva. Migwagwa pakati pemichina inoparadzaniswa pamakwikwi maviri kana kupfuura emagetsi anowanzofanira kushandiswa nemakambani ekutengesa, asi neVLAN kuti motokari inogona kugadziriswa zvakanyatsonaka kuburikidza nemagetsi ekuchinja panzvimbo.
VLANs inounzawo zvimwe zvekuchengetedza zvikwereti pamagetsi makuru kuburikidza nekubvumira kukura kwakanyanya pane zviyero zvine ruzivo rwemunharaunda kune umwe neumwe. Wi-Fi guest network dzinowanzoshandiswa kuburikidza nekusvibisa mafungiro ekushandisa anotsigira VLAN.
Vatican Static uye Dynamic
Vatungamiri veMatare vanowanzoreva maVLAN anosimudzira se "VLAN-port-based VLAN" Hazvina mhosva kuti chii chipi uye muhomwe iyoyo, inova nhengo yeiyo yakafanirwa kugoverwa.
Dynamic VLAN configuration inobvumira mutungamiriri kurondedzera hutano hwehutano maererano nemaitiro ezvirongwa ivo pachavo pane nzvimbo yavo yekushandura nzvimbo. Semuenzaniso, simba reVLAN rinogona kurondedzerwa neurongwa rweateresi dzemuviri ( MAC aderesi) kana mazita e-akhawunti yenethiwekhi.
VLAN Tagging uye Standard VLANs
VLAN tags for network Ethernet inotevera IEEE 802.1Q inoshandiswa mumhizha. Chinoti 802.1Q chinosvika 32 bits (4 bytes ) yedheta inowanikwa muEheadet frame header. Mitsara yekutanga 16 yemunda iyi ine nhamba yakaoma 0x8100 inokonzera Ethernet mafaira kuti aone fomu seyayo ye 802.1Q VLAN. Maviri gumi ekupedzisira emunda uyu ane nhamba yeVLAN, nhamba iri pakati pe1 ne4094.
Nzira dzakanakisisa dzeVLAN administration dzinotsanangura mhando dzakasiyana dzemhando dze virtual network:
- Native LAN: Ethernet VLAN madivayiri anobata mapuranga ose asina kubvumwa seavo vemunharaunda yeLAN kuburikidza. Iko munharaunda yeLAN iVLAN 1, kunyange zvazvo vatungamiri vanogona kuchinja iyi nhamba isina kuwanikwa.
- Kutungamira VLAN: Inoshandiswa kutsigira kure zvakasangana kubva kune network network. Mimwe mitambo inoshandisa VLAN 1 sevatungamiri veVLAN apo vamwe vanogadzira nhamba chaiyo nokuda kwechinangwa ichi (kuti isapesana nedzimwe nzira yekutengesa)
Kugadza VLAN
Pamusoro wepamusoro, vateereri vetaneti vanogadzira VLAN itsva sezvinotevera:
- Sarudza nhamba yakakodzera yeVLAN
- Sarudza pachepa IP pikisheni yepamusoro yezvigadzirwa paVLAN iyo yekushandisa
- Gadzirisa shandura chipikisi neine static kana kushandiswa kwemamiriro. Kugadziriswa kwakasimba kunoda kuti mutungamiri ape nhamba yeVLAN kune rimwe gonji rechinja apo kushandiswa kwakasimba kunoda kugovera urongwa hweMAC mazita kana mazita omudzimai kuNhamba yeVLAN.
- Gadzira nzira yekuendesa pakati peVLAN sezvinodiwa. Kugadzirisa maviri kana kupfuura VLAN kuti vataurirane zvinoda kushandiswa kweVLAN-aware router kana Layer 3 switch .
Izvo zvinoshandiswa zvekutungamirira uye zvishandiso zvinoshandiswa zvakasiyana zvikuru zvichienderana nemichina yakabatanidzwa.
