Lero tipitiliza zokambirana zathu za VLAN ndikukambirana za VTP protocol, komanso malingaliro a VTP Pruning ndi Native VLAN. Tidalankhula kale za VTP m'mavidiyo am'mbuyomu, ndipo chinthu choyamba chomwe chiyenera kubwera m'maganizo mwanu mukamva za VTP ndikuti si trunking protocol, ngakhale imatchedwa "VLAN trunking protocol."
Monga mukudziwa, pali awiri trunking protocols - mwini Cisco ISL protocol, amene sagwiritsidwa ntchito masiku ano, ndi 802.q protocol, amene ntchito maukonde zipangizo kuchokera opanga osiyanasiyana encapsulate trunking magalimoto. Protocol iyi imagwiritsidwanso ntchito pakusintha kwa Cisco. Tanena kale kuti VTP ndi VLAN synchronization protocol, ndiko kuti, idapangidwa kuti igwirizanitse database ya VLAN pama switch onse a netiweki.
Tinatchula mitundu yosiyanasiyana ya VTP - seva, kasitomala, zowonekera. Ngati chipangizocho chimagwiritsa ntchito seva, izi zimakulolani kuti musinthe, kuwonjezera kapena kuchotsa ma VLAN. Makasitomala samakulolani kuti musinthe masinthidwe osinthira, mutha kukonza nkhokwe ya VLAN pokhapokha kudzera pa seva ya VTP, ndipo idzabwerezedwanso kwa makasitomala onse a VTP. Kusintha kwamawonekedwe owonekera sikusintha ku database yake ya VLAN, koma kumangodutsa yokha ndikusamutsa zosinthazo ku chipangizo chotsatira mumachitidwe a kasitomala. Njirayi ndi yofanana ndi kuletsa VTP pa chipangizo china, ndikuchisintha kukhala chotengera cha kusintha kwa VLAN.
Tiyeni tibwerere ku pulogalamu ya Packet Tracer ndi ma network topology omwe takambirana m'phunziro lapitalo. Tidakonza netiweki ya VLAN10 ya dipatimenti yogulitsa ndi netiweki ya VLAN20 ya dipatimenti yotsatsa, kuwaphatikiza ndi ma switch atatu.
Pakati pa ma switch SW0 ndi SW1 kulumikizana kumachitika pa netiweki ya VLAN20, ndipo pakati pa SW0 ndi SW2 pali kulumikizana pa netiweki ya VLAN10 chifukwa tawonjezera VLAN10 ku database ya VLAN ya switch SW1.
Kuti tiganizire ntchito ya VTP protocol, tiyeni tigwiritse ntchito imodzi mwa masiwichi ngati seva ya VTP, ikhale SW0. Ngati mukukumbukira, mwachisawawa zosintha zonse zimagwira ntchito mu seva ya VTP. Tiyeni tipite ku mzere wolamula wosinthira ndikulowetsa chiwonetsero cha vtp status command. Mukuwona ndondomeko yamakono ya VTP protocol ndi 2 ndipo nambala yokonzanso kasinthidwe ndi 4. Ngati mukukumbukira, nthawi zonse kusintha kumapangidwa ku database ya VTP, nambala yokonzanso ikuwonjezeka ndi imodzi.
Chiwerengero chachikulu cha ma VLAN omwe amathandizidwa ndi 255. Chiwerengerochi chimadalira mtundu wa kusintha kwa Cisco, popeza kusintha kosiyana kungathe kuthandizira manambala osiyanasiyana amtundu wapafupi. Chiwerengero cha ma VLAN omwe alipo ndi 7, mu mphindi imodzi tiwona zomwe maukondewa ali. VTP control mode ndi seva, dzina la domain silinakhazikitsidwe, VTP Pruning mode yayimitsidwa, tibwereranso ku izi pambuyo pake. Mitundu ya VTP V2 ndi VTP Traps Generation imayimitsidwanso. Simufunikanso kudziwa zamitundu iwiri yomaliza kuti mudutse mayeso a 200-125 CCNA, chifukwa chake musade nkhawa nazo.
Tiyeni tiwone nkhokwe ya VLAN pogwiritsa ntchito show vlan command. Monga tawonera kale muvidiyo yapitayi, tili ndi maukonde 4 osagwiritsidwa ntchito: 1002, 1003, 1004 ndi 1005.
Imalembanso maukonde awiri omwe tidapanga, VLAN2 ndi 10, ndi netiweki yosasinthika, VLAN20. Tsopano tiyeni tipitirire pakusintha kwina ndikuyika lamulo lomwelo kuti muwone mawonekedwe a VTP. Mukuwona kuti nambala yosinthidwa ya switch iyi ndi 1, ili mu seva ya VTP ndipo zidziwitso zina zonse ndizofanana ndikusintha koyamba. Ndikalowa muwonetsero wa VLAN, ndikutha kuwona kuti tapanga kusintha kwa 3 ku zoikamo, imodzi yocheperako SW2, chifukwa chake nambala yobwereza ya SW0 ndi 1. Tapanga kusintha kwa 3 pazosintha zoyambira zoyambira. kusintha, chifukwa chake chiwerengero chake chosinthidwa chinakwera kufika pa 3.
Tsopano tiyeni tiwone momwe SW2 ilili. Nambala yokonzanso apa ndi 1, zomwe ndi zachilendo. Tiyenera kukonzanso kachiwiri chifukwa 1 zosintha zidapangidwa. Tiyeni tiwone VLAN database.
Tinapanga kusintha kumodzi, kupanga VLAN10, ndipo sindikudziwa chifukwa chake chidziwitsocho sichinasinthidwe. Mwina izi zidachitika chifukwa tilibe netiweki yeniyeni, koma pulogalamu yoyeserera yamapulogalamu, yomwe ingakhale ndi zolakwika. Mukakhala ndi mwayi wogwira ntchito ndi zida zenizeni mukamagwira ntchito ku Cisco, zidzakuthandizani kuposa simulator ya Packet Tracer. Chinanso chothandiza pakapanda zida zenizeni chingakhale GNC3, kapena choyimira cha Cisco network. Ichi ndi emulator yomwe imagwiritsa ntchito machitidwe enieni a chipangizo, monga rauta. Pali kusiyana pakati pa simulator ndi emulator - yoyamba ndi pulogalamu yomwe imawoneka ngati router yeniyeni, koma si imodzi. The emulator mapulogalamu amalenga kokha chipangizo palokha, koma amagwiritsa ntchito mapulogalamu enieni ntchito. Koma ngati mulibe kuthekera koyendetsa mapulogalamu enieni a Cisco IOS, Packet Tracer ndiye njira yanu yabwino kwambiri.
Choncho, tifunika kukonza SW0 ngati seva ya VTP, chifukwa cha izi ndikupita kumayendedwe adziko lonse ndikulowetsa lamulo vtp version 2. Monga ndanenera, tikhoza kukhazikitsa ndondomeko ya protocol yomwe tikufunikira - 1 kapena 2, mu izi. ngati tikufuna mtundu wachiwiri. Kenako, pogwiritsa ntchito vtp mode command, timayika njira ya VTP yosinthira - seva, kasitomala kapena kuwonekera. Pankhaniyi, timafunikira mawonekedwe a seva, ndipo mutalowa mu vtp mode seva lamulo, dongosolo limasonyeza uthenga kuti chipangizocho chiri kale mu seva. Kenako, tiyenera kukonza dera la VTP, lomwe timagwiritsa ntchito vtp domain nwking.org lamulo. Nβchifukwa chiyani zimenezi zili zofunika? Ngati pali chipangizo china pa netiweki chomwe chili ndi nambala yokonzanso kwambiri, zida zina zonse zomwe zili ndi nambala yocheperako zimayamba kutengeranso nkhokwe ya VLAN kuchokera pachidacho. Komabe, izi zimachitika pokhapokha ngati zidazo zili ndi dzina lomwelo. Mwachitsanzo, ngati mumagwira ntchito pa nwking.org, mumasonyeza domain iyi, ngati ku Cisco, ndiye domain cisco.com, ndi zina zotero. Dzina la domeni lazida za kampani yanu limakupatsani mwayi wozisiyanitsa ndi zida za kampani ina kapena zida zilizonse zakunja zapaintaneti. Mukapereka dzina la kampani ku chipangizo, mumachipanga kukhala gawo la netiweki ya kampaniyo.
Chotsatira choti muchite ndikukhazikitsa mawu achinsinsi a VTP. Ndikofunikira kuti wobera, yemwe ali ndi chipangizo chokhala ndi nambala yosinthidwa kwambiri, sangathe kutengera zokonda zake za VTP pakusintha kwanu. Ndimalowetsa mawu achinsinsi a cisco pogwiritsa ntchito vtp password cisco command. Pambuyo pake, kubwereza kwa deta ya VTP pakati pa masinthidwe kutheka kokha ngati mawu achinsinsi akugwirizana. Ngati mawu achinsinsi olakwika agwiritsidwa ntchito, database ya VLAN sidzasinthidwa.
Tiyeni tiyese kupanga ma VLAN ena. Kuti ndichite izi, ndimagwiritsa ntchito lamulo la config t, gwiritsani ntchito lamulo la vlan 200 kuti mupange nambala ya network 200, ndipatseni dzina lakuti TEST ndikusunga zosinthazo ndi lamulo lotuluka. Kenako ndimapanga vlan 500 ina ndikuyitcha TEST1. Ngati tsopano lowetsani lamulo la vlan, ndiye kuti patebulo la ma network pafupifupi osinthira mutha kuwona maukonde awiriwa, omwe palibe doko limodzi lomwe limaperekedwa.
Tiyeni tipitirire ku SW1 ndikuwona mawonekedwe ake a VTP. Tikuwona kuti palibe chomwe chasintha pano kupatula dzina lachidziwitso, kuchuluka kwa VLAN kumakhalabe kofanana ndi 7. Sitikuwona maukonde omwe tidapanga akuwonekera chifukwa mawu achinsinsi a VTP sakugwirizana. Tiyeni tiyike mawu achinsinsi a VTP pa switch iyi ndikulowetsa motsatizana malamulo conf t, vtp pass ndi vtp password Cisco. Dongosololi linanena kuti nkhokwe ya VLAN ya chipangizocho tsopano ikugwiritsa ntchito mawu achinsinsi a Cisco. Tiyeni tionenso momwe VTP ilili kuti tiwone ngati zomwe zafotokozedwazo zabwerezedwanso. Monga mukuonera, chiwerengero cha ma VLAN omwe alipo chawonjezeka kufika pa 9.
Mukayang'ana database ya VLAN ya switch iyi, mutha kuwona kuti maukonde a VLAN200 ndi VLAN500 omwe tidapanga adawonekera momwemo.
Zomwezo ziyenera kuchitika ndi switch yomaliza SW2. Tiyeni tilowe muwonetsero vlan lamulo - mukhoza kuona kuti palibe kusintha kwachitika mmenemo. Momwemonso, palibe kusintha kwa VTP. Kuti kusinthaku kusinthe zambiri, muyeneranso kukhazikitsa mawu achinsinsi, ndiye kuti, lowetsani malamulo omwewo ngati a SW1. Pambuyo pake, chiwerengero cha ma VLAN mu SW2 chidzakwera kufika pa 9.
Ndicho chimene VTP ndi yake. Ichi ndi chinthu chabwino chomwe chimangosintha zidziwitso pazida zonse zamakasitomala zitasintha pa chipangizo cha seva. Simufunikanso kusintha pamanja nkhokwe ya VLAN ya masiwichi onse - kubwereza kumachitika zokha. Ngati muli ndi zida za netiweki 200, zosintha zomwe mumapanga zidzasungidwa pazida mazana awiri nthawi imodzi. Zikatero, tiyenera kuwonetsetsa kuti SW2 ndi kasitomala wa VTP, ndiye tiyeni tipite ku zoikamo ndi config t command ndikulowetsa vtp mode kasitomala lamulo.
Chifukwa chake, mu network yathu yokha yosinthira yoyamba ili mu VTP Server mode, enawo amagwira ntchito mu VTP Client mode. Ngati tsopano ndipita ku zoikamo za SW2 ndikulowetsa lamulo la vlan 1000, ndidzalandira uthengawo: "Kukonza VTP VLAN sikuloledwa pamene chipangizocho chili mumayendedwe a kasitomala." Chifukwa chake, sindingathe kusintha nkhokwe ya VLAN ngati chosinthira chili mu kasitomala wa VTP. Ngati ndikufuna kusintha, ndiyenera kupita ku seva yosinthira.
Ndimapita ku zoikamo za SW0 ndikulowetsa malamulo vlan 999, dzina IMRAN ndikutuluka. Netiweki yatsopanoyi yawonekera mu nkhokwe ya VLAN ya switch iyi, ndipo ngati ndipita ku database ya kasitomala switch SW2, ndiwona kuti zomwezi zawonekera apa, ndiye kuti, kubwereza kwachitika.
Monga ndanenera, VTP ndi pulogalamu yabwino kwambiri, koma ikagwiritsidwa ntchito molakwika, imatha kusokoneza maukonde onse. Chifukwa chake, muyenera kusamala kwambiri mukamayendetsa netiweki yakampani ngati dzina la domain ndi mawu achinsinsi a VTP sanakhazikitsidwe. Pankhaniyi, onse owononga ayenera kuchita ndi pulagi chingwe chosinthira wake mu maukonde zitsulo pakhoma, kulumikiza ofesi iliyonse lophimba ntchito DTP protocol ndiyeno, pogwiritsa ntchito thunthu analenga, kusintha mfundo zonse ntchito VTP protocol. . Mwanjira imeneyi, wowononga akhoza kuchotsa ma VLAN onse ofunika, pogwiritsa ntchito mfundo yakuti nambala yosinthidwa ya chipangizo chake ndi yapamwamba kuposa chiwerengero chosinthidwa cha ma switch ena. Izi zikachitika, zosintha zamakampani zimangolowetsa zidziwitso zonse za database ya VLAN ndi zidziwitso zotsatiridwa ndikusintha koyipa, ndipo netiweki yanu yonse idzagwa.
Izi ndichifukwa choti makompyuta amalumikizidwa pogwiritsa ntchito chingwe cha netiweki ku doko linalake losinthira lomwe VLAN 10 kapena VLAN20 imaperekedwa. Ma netiwekiwa akachotsedwa pankhokwe ya LAN yosinthira, ingoyimitsa doko la netiweki yomwe palibe. Nthawi zambiri, maukonde akampani amatha kugwa ndendende chifukwa masiwichi amangoletsa madoko okhudzana ndi ma VLAN omwe adachotsedwa pakusinthidwa kotsatira.
Kuti mupewe vuto lotere kuti lisachitike, muyenera kukhazikitsa dzina lachidziwitso cha VTP ndi mawu achinsinsi kapena gwiritsani ntchito Cisco Port Security Mbali, yomwe imakupatsani mwayi wowongolera ma adilesi a MAC a ma switch ports, ndikuyambitsa zoletsa zosiyanasiyana pakugwiritsa ntchito kwawo. Mwachitsanzo, ngati wina ayesa kusintha adilesi ya MAC, doko limatsika nthawi yomweyo. Tikhala tikuyang'anitsitsa mbali iyi ya Cisco masinthidwe posachedwa, koma pakadali pano zomwe muyenera kudziwa ndikuti Port Security imakupatsani mwayi woonetsetsa kuti VTP imatetezedwa kwa wowukira.
Tiyeni tifotokoze mwachidule zomwe makonzedwe a VTP ndi. Uku ndiye kusankha kwa mtundu wa protocol - 1 kapena 2, magawo a VTP - seva, kasitomala kapena kuwonekera. Monga ndanenera kale, mawonekedwe omalizawa sasintha nkhokwe ya VLAN ya chipangizocho, koma amangotumiza zosintha zonse kuzipangizo zoyandikana nazo. Otsatirawa ndi malamulo operekera dzina lachidziwitso ndi mawu achinsinsi: vtp domain <domain name> ndi vtp password <password>.
Tsopano tiyeni tikambirane za VTP Pruning zoikamo. Mukayang'ana pa topology yamaneti, mutha kuwona kuti masiwichi onse atatu ali ndi database ya VLAN, zomwe zikutanthauza kuti VLAN10 ndi VLAN20 ndi gawo la masiwichi atatu onse. Mwaukadaulo, kusintha SW3 sikufuna VLAN2 chifukwa ilibe madoko a netiweki iyi. Komabe, mosasamala kanthu za izi, magalimoto onse otumizidwa kuchokera pakompyuta ya Laptop20 kudzera pa netiweki ya VLAN0 amafika pa switch ya SW20 ndipo amadutsa thunthu kupita ku madoko a SW1. Ntchito yanu yayikulu ngati katswiri wapa netiweki ndikuwonetsetsa kuti deta yocheperako yomwe ingatheke imafalikira pamaneti. Muyenera kuonetsetsa kuti deta yofunikira imafalitsidwa, koma mungachepetse bwanji kufalitsa kwa chidziwitso chomwe sichikufunika ndi chipangizocho?
Muyenera kuwonetsetsa kuti magalimoto opita ku zida za VLAN20 sakuyenda kupita ku madoko a SW2 kudzera mu thunthu ngati sikofunikira. Ndiye kuti, kuchuluka kwa magalimoto a Laptop0 kuyenera kufika pa SW1 kenako kumakompyuta pa VLAN20, koma zisapitirire doko loyenera la SW1. Izi zitha kuchitika pogwiritsa ntchito kudulira kwa VTP.
Kuti tichite izi, tiyenera kupita ku zoikamo VTP seva SW0, chifukwa monga ndanenera kale, VTP zoikamo zikhoza kupangidwa kudzera pa seva, kupita ku zoikamo kasinthidwe padziko lonse ndi kulemba vtp kudulira lamulo. Popeza Packet Tracer ndi pulogalamu yongoyerekeza, palibe lamulo lotere mumayendedwe ake amzere. Komabe, ndikalemba vtp kudulira ndikusindikiza Enter, dongosolo limandiuza kuti vtp kudulira kulibe.
Pogwiritsa ntchito chiwonetsero cha vtp status command, tidzawona kuti VTP Pruning mode ili m'malo olemala, kotero tifunika kuzipangitsa kuti zikhalepo pozisunthira kumalo otsegulira. Titachita izi, timatsegula njira ya VTP Kudulira pamasinthidwe onse atatu a netiweki yathu mkati mwa netiweki.
Ndiroleni ndikukumbutseni zomwe VTP Pruning ndi. Tikayambitsa njirayi, sinthani seva SW0 idziwitsa switch SW2 kuti VLAN10 yokha ndiyomwe imakhazikitsidwa pamadoko ake. Pambuyo pake, sinthani SW2 ikuwuzani SW1 kuti sifunika magalimoto ena kupatula magalimoto opangira VLAN10. Tsopano, chifukwa cha Kudulira kwa VTP, sinthani SW1 ili ndi chidziwitso kuti sichiyenera kutumiza magalimoto a VLAN20 pathunthu la SW1-SW2.
Izi ndizosavuta kwa inu ngati woyang'anira maukonde. Simusowa kuti pamanja kulowa malamulo chifukwa lophimba ndi wanzeru kutumiza ndendende zimene enieni chipangizo Intaneti amafuna. Ngati mawa muyika dipatimenti ina yotsatsa mnyumba yotsatira ndikulumikiza netiweki yake ya VLAN20 kuti musinthe SW2, kusinthako kumauza switch SW1 kuti tsopano ili ndi VLAN10 ndi VLAN20 ndikuyifunsa kuti itumize magalimoto pamanetiweki onsewa. Izi zimasinthidwa pafupipafupi pazida zonse, zomwe zimapangitsa kulumikizana bwino.
Palinso njira ina yofotokozera kufalikira kwa magalimoto - ndiko kugwiritsa ntchito lamulo lomwe limalola kufalitsa kwa data kokha kwa VLAN yotchulidwa. Ndikupita ku zoikamo lophimba SW1, kumene ine ndimakonda doko Fa0/4, ndi kulowa malamulo int fa0/4 ndi switchport thunthu analola vlan. Popeza ndikudziwa kale kuti SW2 ili ndi VLAN10 yokha, nditha kuuza SW1 kuti ilole magalimoto okha pamanetiwo padoko lake pogwiritsa ntchito lamulo lololedwa la vlan. Chifukwa chake ndidakonza doko la Fa0/4 kuti lizinyamula magalimoto okha a VLAN10. Izi zikutanthauza kuti dokoli sililola kuchuluka kwa magalimoto kuchokera ku VLAN1, VLAN20, kapena netiweki ina iliyonse kupatula yomwe yatchulidwayo.
Mutha kukhala mukuganiza kuti ndibwino kugwiritsa ntchito iti: Kudulira kwa VTP kapena lamulo lololedwa la vlan. Yankho lake ndi lokhazikika chifukwa nthawi zina zimakhala zomveka kugwiritsa ntchito njira yoyamba, ndipo zina ndizomveka kugwiritsa ntchito yachiwiri. Monga woyang'anira maukonde, zili ndi inu kusankha njira yabwino kwambiri. Nthawi zina, chisankho chokonzekera doko kuti alole magalimoto kuchokera ku VLAN inayake akhoza kukhala abwino, koma ena akhoza kukhala oipa. Pankhani ya netiweki yathu, kugwiritsa ntchito lamulo lololedwa la vlan kungakhale koyenera ngati sitisintha ma network topology. Koma ngati wina pambuyo pake akufuna kuwonjezera gulu la zida zogwiritsa ntchito VLAN2 ku SW 20, zingakhale bwino kugwiritsa ntchito njira yodulira ya VTP.
Chifukwa chake, kukhazikitsa VTP Kudulira kumaphatikizapo kugwiritsa ntchito malamulo otsatirawa. Lamulo lodulira la vtp limapereka kugwiritsa ntchito njira iyi. Ngati mukufuna kukonza VTP Kudulira kwa doko la thunthu kuti mulole magalimoto a VLAN kuti adutse pamanja, ndiye gwiritsani ntchito lamulo kuti musankhe mawonekedwe a doko la thunthu <#>, yambitsani thunthu la switchport mode thunthu ndikulola kufalikira kwa magalimoto. ku netiweki inayake pogwiritsa ntchito switchport trunk yololedwa vlan command .
Mu lamulo lomaliza mutha kugwiritsa ntchito magawo 5. Zonse zikutanthawuza kuti kutumiza kwa magalimoto kwa ma VLAN onse kumaloledwa, palibe - kutumiza kwa magalimoto kwa ma VLAN onse ndikoletsedwa. Ngati mugwiritsa ntchito zowonjezera, mutha kuwonjezera kuchuluka kwa magalimoto pamaneti ena. Mwachitsanzo, timalola magalimoto a VLAN10, ndipo ndi lamulo lowonjezera tikhoza kulola kuti magalimoto a VLAN20 adutse. Lamulo lochotsa limakupatsani mwayi wochotsa imodzi mwa maukonde, mwachitsanzo, ngati mugwiritsa ntchito chotsani 20 parameter, magalimoto a VLAN10 okha ndi omwe atsala.
Tsopano tiyeni tione VLAN mbadwa. Tanena kale kuti VLAN yachibadwidwe ndi netiweki yeniyeni yodutsa magalimoto osakhazikika padoko linalake.
Ndimalowa m'makonzedwe enieni a doko monga momwe zasonyezedwera ndi mutu wa mzere wa SW(config-if)# ndikugwiritsa ntchito lamulo switchport trunk native vlan <network number>, mwachitsanzo VLAN10. Tsopano magalimoto onse pa VLAN10 adzadutsa mu thunthu losatchulidwa.
Tiyeni tibwerere ku topology yomveka bwino pawindo la Packet Tracer. Ngati ndigwiritsa ntchito switchport trunk native vlan 20 command pa switch port Fa0/4, ndiye kuti magalimoto onse pa VLAN20 adzadutsa mu Fa0/4 - SW2 thunthu losatchulidwa. Kusintha kwa SW2 kukalandira kuchuluka kwa magalimotowa, imaganiza kuti: "awa ndi magalimoto osatchulidwa, zomwe zikutanthauza kuti ndiyenera kupita ku VLAN ya komweko." Pakusintha uku, VLAN yakubadwa ndi netiweki ya VLAN1. Ma Network 1 ndi 20 sanalumikizidwe mwanjira iliyonse, koma popeza mtundu wa VLAN wamba umagwiritsidwa ntchito, tili ndi mwayi woyendetsa magalimoto a VLAN20 kupita ku netiweki yosiyana kotheratu. Komabe, kuchuluka kwa magalimotowa kudzakhala kosasunthika, ndipo ma network omwewo ayenera kukhala ofanana.
Tiyeni tione izi ndi chitsanzo. Ndilowa muzokonda za SW1 ndikugwiritsa ntchito lamulo la switchport trunk native vlan 10. Tsopano magalimoto aliwonse a VLAN10 adzatuluka pa doko la thunthu losatchulidwa. Ikafika ku doko la SW2, chosinthiracho chidzamvetsetsa kuti chiyenera kutumiza ku VLAN1. Chifukwa cha chisankho ichi, magalimoto sangathe kufika pa makompyuta a PC2, 3 ndi 4, chifukwa amalumikizidwa ndi ma doko olowera ku VLAN10.
Mwaukadaulo, izi zipangitsa kuti dongosololi linene kuti VLAN yachibadwidwe cha doko Fa0/4, yomwe ili gawo la VLAN10, sichikugwirizana ndi doko Fa0/1, lomwe ndi gawo la VLAN1. Izi zikutanthauza kuti madoko omwe atchulidwa sangathe kugwira ntchito mumtundu wa thunthu chifukwa cha kusagwirizana kwa VLAN.
Zikomo chifukwa chokhala nafe. Kodi mumakonda zolemba zathu? Mukufuna kuwona zambiri zosangalatsa? Tithandizeni potipatsa oda kapena kulimbikitsa anzathu, 30% kuchotsera kwa ogwiritsa ntchito a Habr pa analogi yapadera yamaseva olowera, omwe tinapangira inu: (ikupezeka ndi RAID1 ndi RAID10, mpaka 24 cores mpaka 40GB DDR4).
