Yintoni iVLAN? IiVLAN kufuneka zahlulwe njani?

Umhlobo ukhankanye indlela yokwahlulahlula ii-vlans, kodwa eneneni, ukwahlulahlula i-vlans kubalulekile kwizicelo zetekhnoloji yenethiwekhi. Iinethiwekhi ezininzi zifuna ukwahlulahlula kwe-vlan. Namhlanje, masifunde kunye ngalo mba.
Inkcazo ye-VLAN:
I-VLAN sisishunqulelo seNethiwekhi yeNdawo yeNgingqi yeNgingqi ngesiNgesi, ekwaziwa njengenethiwekhi yendawo enenyani. Bubuchwephesha obuqonda amaqela okusebenza abonakalayo ngokwahlulahlula ngokusengqiqweni izixhobo ngaphakathi kuthungelwano lwendawo yendawo zibe ngamacandelo othungelwano endaweni yokuzahlula ngokwasemzimbeni. Ukwahlulahlula iiVLAN, kufuneka uthenge izixhobo zenethiwekhi ezixhasa ukusebenza kweVLAN.
Injongo yokwahlula iiVLAN:
I-VLAN icetywayo ukujongana nemiba yosasazo kunye nokhuseleko lwe-Ethernet, kunye nokusasazwa kunye ne-unicast traffic ngaphakathi kweVLAN enye ayiyi kuthunyelwa kwezinye iiVLAN. Nokuba iikhompyuter ezimbini ezikwicandelo lothungelwano olufanayo azikho kwi-VLAN enye, imijelo yazo yosasazo eyahlukeneyo ayiyi kuthunyelwa enye kwenye.
Ukwahlula ii-VLAN kunceda ukulawula i-traffic, ukunciphisa utyalo-mali lwesixhobo, ukwenza lula ulawulo lwenethiwekhi, kunye nokuphucula ukhuseleko lwenethiwekhi. Ngenxa ye-VLAN yokwahlula izaqhwithi zokusasaza kunye nonxibelelwano phakathi kweeVLAN ezahlukeneyo, unxibelelwano phakathi kweeVLAN ezahlukeneyo kufuneka luxhomekeke kwii-routers okanye kwi-switch-layer switches.
Indlela yokwahlulahlula kweVLAN:
Kukho iindlela ezine zokwahlulahlula iiVLAN, nganye ineengenelo zayo kunye nezinto ezingeloncedo. Xa ukwahlula iiVLAN kuthungelwano, kuyimfuneko ukukhetha indlela efanelekileyo yokwahlula ngokusekelwe kwimeko yokwenene yothungelwano.
1. I-VLAN esekelwe kulwahlulo lwezibuko: Abavelisi abaninzi bothungelwano basebenzisa amazibuko okutshintsha ukwahlula amalungu eVLAN. Njengoko igama licebisa, izibuko esekwe kwi-VLAN ukwahlulahlula kubhekisa ekuchazeni izibuko ezithile zokutshintsha njengeVLAN.

Ukwahlulahlula kweVLAN okusekwe kumazibuko yeyona ndlela ixhaphakileyo yokwahlulahlula kweVLAN. Iinzuzo zokwahlulahlula iiVLAN ezisekelwe kumazibuko zilula kwaye zicacile, kwaye ulawulo lukwaluncedo kakhulu. Ukungalungi kukuba ulondolozo lunzima.
2. Ulwahlulo lweVLAN olusekelwe kwidilesi ye-MAC: Ikhadi ngalinye lothungelwano linedilesi yendawo eyodwa kwihlabathi jikelele, eyidilesi ye-MAC. Ngokusekwe kwidilesi ye-MAC yekhadi lothungelwano, iikhomputha ezininzi zinokuhlulwa zibe yiVLAN enye.
Inzuzo enkulu yale ndlela kukuba xa indawo yendawo yomsebenzisi ihamba, oko kukuthi, xa utshintshela ukusuka kwelinye iswitshi ukuya kwelinye iswitshi, iVLAN ayifuni ukuphinda iqwalaselwe; Ukungalungi kukuba xa uqalisa iVLAN, bonke abasebenzisi kufuneka bayiqwalasele, kwaye umthwalo kubasebenzi unzima kakhulu.
3. Yahlula iiVLAN ngokusekwe kumaleko womnatha: Le ndlela yokwahlula iiVLAN isekwe kwidilesi yomaleko womnatha okanye uhlobo lweprotocol yenginginya nganye, kunokuba kuthungelwano. Qaphela: Le ndlela yokwahlulahlula kweVLAN ilungele uthungelwano lwendawo ebanzi kwaye ayifuni uthungelwano lwengingqi.
4. Ukuhlelwa kweVLAN okusekwe kwi-IP multicast: IP multicast eneneni yinkcazo yeVLAN, nto leyo ethetha ukuba iqela lemulticast yiVLAN. Le ndlela yokwahlula-hlula yandisa ii-VLAN kuthungelwano lwendawo ebanzi kwaye ayifanelekanga kuthungelwano lwengingqi yendawo, njengoko isikali sothungelwano lwamashishini ayikafikeleli kumlinganiselo omkhulu kangaka.
Kucacile ukuba zonke iitekhnoloji zeVLAN azifanelekanga ngokupheleleyo kusetyenziso lwenethiwekhi. Emva kokufumana ukuqonda okubanzi kweeVLANs, kufuneka sikwazi ukwenza izigwebo ezichanekileyo malunga nokuba ukwahlula kweVLAN kuyimfuneko ngokusekelwe kwindawo yethu yenethiwekhi.
Khetha imo yendlela yokwahlula yeVLAN efanelekileyo
Abasebenzi abaninzi bobugcisa bayazi kuphela ukuba ukwahlula kweVLAN kunokuphucula ukusebenza kothumelo lwenethiwekhi, kodwa abaqapheli ukuba imowudi yokwahlulahlula yeVLAN engafanelekanga iya kunciphisa ukusebenza kwenethiwekhi. Ngenxa yeemeko ezahlukeneyo zothungelwano olwahlukeneyo, eyona ndlela ifanelekileyo yokwahlulahlula kweVLAN yokusetyenziswa kwayo yahlukile. Apha ngezantsi, siza kucacisa ukuba yeyiphi imowudi yokwahlulahlula yeVLAN enengqiqo ngakumbi kuthungelwano lwamashishini kusetyenziswa imizekelo.
Umzekelo, kwinethiwekhi yenkampani, kukho iikhomputha ze-43 zabathengi, apho i-35 i-desktop computers kunye ne-8 yi-laptops. I-traffic yenethiwekhi ayinkulu kakhulu. Ngenxa yedatha ebuthathaka kwisebe lezemali abaqeshwa abaqhelekileyo abangafuniyo ukuyibona, ukuze kuphuculwe ukhuseleko lothungelwano, ulawulo lothungelwano lugqibe ekubeni lwahlule uthungelwano lube ziiVLAN ukwahlula unxibelelwano phakathi kwabasebenzi abaqhelekileyo kunye neePC zabasebenzi besebe lezemali.
Iimfuno zesicelo: Ukususela kwinkcazo engentla, kunokubonwa ukuba ishishini lihlula iiVLAN ukuphucula ukhuseleko, ngelixa ukuphuculwa komsebenzi wokuhanjiswa kwenethiwekhi akuyona injongo ephambili. Ngenxa yenani eliqingqiweyo labathengi kwishishini, iilaptops zinamandla okushukuma. Kumsebenzi wemihla ngemihla, abaphathi badla ngokuhambisa iilaptops ukuya kumagumbi okuhlangana ukuze bahlangabezane neemfuno zomsebenzi ophathwayo. Kule meko, imowudi yokwahlula yeVLAN esekwe kumazibuko ayifanelekanga kwishishini, kwaye eyona ndlela ifanelekileyo yokwahlulahlula kweVLAN isekwe kwiidilesi zeMAC.

Ke kumashishini, eyona ndlela ifanelekileyo yokwahlulahlula kweVLAN isekwe kulwahlulo lwezibuko kunye nokwahlulwa kwedilesi ye-MAC. Kuthungelwano lwamashishini kunye nenani elincinci labathengi kunye nesidingo esihlala sikhona somsebenzi weselula, ukwahlula iiVLAN ezisekelwe kwiidilesi ze-MAC yeyona ndlela yokwahlulahlula. Kuthungelwano lwamashishini kunye nenani elikhulu labathengi kwaye akukho mfuneko ye-ofisi ehambayo, iiVLAN zinokwahlulwa ngokusekelwe kumachweba. Isishwankathelo, khetha imo ye-VLAN efanelekileyo yokwahlula ngokusekelwe kwiimfuno zenethiwekhi.
Isiphelo:
Ukwahlulahlula iiVLAN kubonakala kuyisihloko, kodwa kwizicelo eziphathekayo, bambalwa abantu abaye bakwazi ukusebenzisa kakuhle ukwahlulahlula kweVLAN njengesixhobo solawulo. Okubaluleke ngakumbi, ezinye iinethiwekhi azifuni ukwahlula kwe-VLAN, kodwa ngenxa yoko, abasebenzi bezobugcisa bahlula ii-VLAN kubo, okukhokelela ekunciphiseni ukunxibelelana kwenethiwekhi. Kuncinci okwaziwayo ukuba ukwahlulahlula okufanelekileyo kweVLAN kunokuphucula ukusebenza kakuhle kothumelo lwenethiwekhi, singasathethi ke ngokuqwalasela ukwahlulahlula kweVLAN njengesisombululo esilungileyo sokucotha isantya sothungelwano.
