Niki insinga 8 muri kabili ya ethernet ikora

Vlan (virtual moteri yakarere) ni tekinoroji itumanaho igabanya umurongo wumubiri mubice byinshi byatangajwe. Buri Vlan ni urugero rwatangajwe aho kuba ingabo zishobora gutuma mu buryo butaziguye, mugihe itumanaho hagati ya Venne zitandukanye rirabujijwe. Nkigisubizo, ubutumwa bwo gutangaza bugarukira kuri VLAN imwe.

Kuki Vlans ikenewe

Imiyoboro ya Ethernet ya mbere yari imbuga zamakuru zishingiye kuri CSMA / CD (Ubwumvikane buke bwo kugera / kuyaburaho) byakoresheje uburyo bwo gutumanaho. Iyo umubare w'ingabo wiyongereye, wateje impaka zikomeye, utanga amakuru, kwangirika kw'imikorere ikomeye, ndetse no mu miyoboro y'urusobe. Nubwo guhuza Lans ukoresheje ibikoresho 2 byashoboraga gukemura ibibazo byo kugongana, biracyatsindwaho ubutumwa bwo gutangaza ubutumwa no kunoza imico. Ibi byatumye habaho iterambere ryikoranabuhanga rya Vlan, rigabanijwe lan mumirongo myinshi yumvikana; Buri Vlan yerekana indangarubuga yatangajwe, ifasha itumanaho muri VLAN nkaho ari LAN mugihe arinda itumanaho hagati kandi rifite impushya zo gutangaza ubutumwa muri VLAN.

Icyitegererezo 1: Uruhare rwa Vlans

Rero, Vlans ifite ibyiza bikurikira:

· Kugabanya ibyatsi byatangajweho: Impapuro zitangazwa zigarukira muri VLAN, kubungabunga umurongo unDadth no kuzamura ubushobozi bwo gutunganya imiyoboro.
· Engera umutekano wa LAN: Ubutumwa buva kuri Vlans butandukanye mugihe cyo kohereza, bivuze kubakoresha muri VLAN imwe ntibishobora kuvugana mu buryo butaziguye nabakoresha muyindi VLAN.
· Kongera umuyoboro ukomeye: Amakosa abujijwe kumvikanisha imwe, bityo ibibazo biri muri VLAN imwe ntibigira ingaruka kumikorere isanzwe yabandi.
· Flexible Kubaka akazi: Vlans irashobora kugabana abakoresha muburyo butandukanye, bituma abanyamuryango bakazi runaka bakora batabazwaga ahantu runaka, gukora imiyoboro yo kubaka no gufata neza kandi byoroshye.

Vlan na Subnet

Nukugabanye urusobe rwa IP kuri aderesi nyinshi, igipimo cyo gukoresha hasi cya IP cya Aderesi ya Aderesi hamwe na aderesi za IP ebyiri zirashobora gukemurwa. Bisa na Vlans, amasuka birashobora kandi gutandukanya itumanaho hagati ya seja. Abashitsi ba Vlans batandukanye ntibashobora kuvugana mu buryo butaziguye, nkuko abashyitsi bafite amatsinda atandukanye ntibashobora. Ariko, nta yandi manza yo kwandikirana byombi.

Vlan	Subnet
Itandukaniro	Ikoreshwa mu kugabana urwego 2.
	Nyuma yo kugena Vlan interfaces, abakoresha muburyo butandukanye barashobora kuvugana gusa niba inzira zashyizweho.
	Abasorwamo bagera kuri 4094 barashobora gusobanurwa; Umubare wibikoresho biri muri VLAN ntibigarukira.
Isano	Muri VLAN imwe, imwe cyangwa nyinshi zitandukanye zirashobora gusobanurwa.

Vlan tag na vlan id

Gushoboza guhinduranya ubutumwa bwa Vlans butandukanye, umurima ugaragaza amakuru ya Vlan agomba kongerwaho mubutumwa. Ieee 802.1q yerekana ko tagi 4-byte vlan Vlan (bizwi nka Vlan tag) yongerwaho amakuru ya ethernet kugirango amenye amakuru ya Vlan.

Umurima wa vid muri data yerekana VLAN kuri gahunda yamakuru ari iyamakuru; Amakuru yamakuru arashobora gutangwa gusa muri Vlan yagenwe. Umurima wa vid ugereranya indangamuntu ya VLAN, ishobora kuva kuri 0 kugeza kuri 4095. Kuva 0 na 4095 byabitswe kuri protomeri, bikaba abakoresha

Kubwibyo, gukorana nibikoresho, hindura Imigaragarire igomba kumenya amakadiri gakondo ya Ethernet hanyuma wongere cyangwa wambure Vlan Tags mugihe cyo kohereza. ID ya VLANI YIFATANYIJE GUHINDUKA N'UMUNTU W'INGENZI VLAN (PR PRC ID ID, Pngiro).

Ubwoko bwa Vlan Interfaces na Vlan Tag Gukoresha uburyo

Mu miyoboro iriho, abakoresha ba Vlan imwe barashobora guhuzwa no guhinduranya bitandukanye, kandi hashobora kubaho ibisog byinshi bikaba binyuramo. Niba ushinzwe gukora akenewe, interineti iri hagati yimpimbazi igomba kuba ishobora kumenya no kohereza amakuru ya Data muri Vlans nyinshi icyarimwe. Ukurikije ibintu bihujwe nuburyo amakadiri atunganywa, hari ubwoko butandukanye bwumukoresha wa VLAN kugirango akire amasano atandukanye.
