Waa maxay 8 fiilooyinka fiilooyinka ethernet ah

VLAN (Shabakad maxalli ah oo maxalliga ah) waa tikniyoolajiyad isgaarsiineed oo macno ahaan u kala qaybinaysa kulan jir ahaaneed oo loogu talagalay xayawaanada badan ee baahinta leh. Vlan kasta waa qeyb-bixinno-baahin halkaas oo martigeliyadu si toos ah ula xiriiri karaan, halka wada xiriirka ka dhexeeya VLUNS kala duwan tahay. Natiijo ahaan, farriimaha baahinta ah waxay ku xadidan yihiin hal vfan.

Maxaa loogu baahan yahay VLUS

Shabakadaha hore ee Ethernet waxay ahaayeen teknolojiyadda isku xirka macluumaadka ee ku saleysan CSMMA / CD (oo dareenka xamuulka ah ee ogaanshaha isku-darka / isku-darka shilka) ee loo adeegsaday isgaarsiinta la wadaago. Markii tirada ciidammada ay kordheen, waxay horseeday isku dhacyo halis ah, oo ah duufaano la baahiyo, xaalufinta waxqabadka ee muhiimka ah, iyo xitaa isbadalka shabakada. In kasta oo laxiriira lamaanaha loo adeegsado lakabka lakabka 2 ee lakab ah ayaa xallin kara arrimaha isku dhaca, haddana waxaa lagu guuldareystay inay ka go'do farriimaha baahinta iyo wanaajinta tayada shabakadda. Tani waxay horseeday horumarinta tikniyoolajiyadda VLAN, oo qaylisa ku taal Lan in dhowr VLIC ah oo macquul ah; VLAN kastaa wuxuu matalaa xog baahin, taasoo awood u siineysa isgaarsiinta gudaheeda VLAN sida haddii ay ka hor tagayso isgaarsiinta Inter-VLAN iyo in lagu xiro farriimaha warbaahinta ee Vlan.

Sawirka 1: Doorka VLANS

Sidaa darteed, VLANs waxay leeyihiin faa'iidooyinka soo socda:

· Xaddididda Domains Domains: Domain-ka la-baahineed waxay ku koobnaadaan gudaha VLAN, oo kaashanaya xarkaha xarkaha iyo kor u qaadida awoodda shabakadda shabakadda.
· Kobcinta amniga LAN: Farriimaha ka socda VLUNs kala duwan ayaa go'doonsan inta lagu gudajiro gudbinta, taasoo la micno ah isticmaaleyaasha ka mid ah VLAN si toos ah ugula xiriiri karin isticmaaleyaasha vlan.
Kordhinta adkaanta shabakada
Dhismaha shaqada kacsan ee dabacsan: VLANs-ka ayaa u qaybin kara isticmaaleyaasha koox-kooxeedyo kala duwan, iyagoo u oggolaanaya xubnaha isla goobta shaqada inay ku shaqeeyaan iyada oo aan la xadidin dhisme gaar ah, oo saadaalineysa shabakad dhisme iyo dayactir oo dabacsan oo dabacsan.

Vlan vs. balarnet

Adoo ku sii qaybsanaanta shabakadda shabakadda ee cinwaannada IP-ga ee cinwaanno dhawr ah, heerka adeegsiga hoose ee cinwaanka IP-ga ee Cinwaanka IP-ga iyo Cinwaanka IP-ga ee laba-heer ah ayaa wax laga qaban karaa. La mid ah VLANs, buufinnada ayaa sidoo kale ka go'day wada xiriirka ka dhexeeya kooxaha martida loo yahay. Martigaliyayaasha ay leeyihiin VLANs kala duwan ma wada xiriirin karaan si toos ah, sida martida loo leeyahay ee qeybaha kala duwan ee malaha. Si kastaba ha noqotee, majiraan xiriir toos ah oo u dhexeeya labada.

Vfan	Badeto
Kala duwansho	Waxaa loo isticmaalaa in lagu kala qaybiyo lakabka 2 shabakadda.
	Ka dib markii la dejiyo isdhaafsiga VLAN, isticmaaleyaasha ku jira VLANs kala duwan ayaa la xiriiri kara oo keliya haddii marinnada loo dejiyo.
	Illaa 4094 VLANs waa la qeexi karaa; Tirada aaladaha gudaha vlan ma xadidan tahay.
Xiriirto	Isla vlan, hal ama in ka badan oo hoosaadyo ah ayaa lagu qeexi karaa.

VLAN TAG iyo VLAN ID

Si loo suurto geliyo isu beddelashada fariimaha ka soo jeeda VLANs kala duwan, goob lagu aqoonsado macluumaadka VLAN waa in lagu daraa fariimaha. Borotokoolka 'IEEE 802.1Q Bocotorol' ayaa qeexaya in 4-BYTE TO BLAN TAG (oo loo yaqaan 'VLAN TAG' in lagu daro xirmooyinka xogta EtherNet si loo garto macluumaadka VLAN.

Goobta Vid ee xogta xogta ayaa tilmaamaysa VLAN oo ay xogtu ka tirsan tahay; Xogta xogta waxaa lagu kala qaadi karaa oo keliya gudaha loo qoondeeyay Vlan. Goobta VID waxay matalaysaa Aqoonsiga VLAN, oo u dhexeeyey 0 ilaa 4095. Tan iyo 4095 waxaa lagu habeeyay aaladaha 'VLAN's The Indepens-ka oo ay ku xirnaadaan oo ay ku xirnaadaan xargaha' VLENET 'oo ay ku xirnaadaan oo ay ka helaan xirmooyinka' Ethernet 'oo aan lahayn calaamadaha VLAN.

Sidaa darteed, in lala macaamilo aaladan, isweydaarsiga beddelayaashu waa inay aqoonsadaan xirmooyinka Ethernet-ka ee Ethernet-ka oo ku dar ama strip vlan calaamadaha inta lagu gudajiro gudbinta. The Vlan Tag wuxuu intaas raacay wuxuu u dhigantaa interface-ka caadiga ah ee vlan (dekada 'dereford vlan id', pvid).

Noocyada vlan Interfaces iyo farsamooyinka farsamada ee VLAN TAG

Shabakadaha hadda jira, dadka isticmaala ee la mid ah VLAN isku mid ah ayaa lagu xiri karaa wareejinta kala duwan, waxaana jiri kara VLANs fara badan oo ku baahsan wareejinta. Haddii loo baahan yahay is-weydaarsiga is-gaadhsiinta inuu muhiim yahay, is-dhexgalka u dhexeeya wareejinta waa inay awood u yeeshaan inay aqoonsadaan oo ay u diraan xirmooyinka xogta ka yimaada VLANs badan isla mar. Iyada oo ku xidhan walxaha iskuxiran iyo sida loo farsameeyo xargaha, waxaa jira noocyo kala duwan oo ah noocyo kala duwan oo VLAN ah si loogu habeeyo xiriirro kala duwan iyo xiriirin.
