Tisanalowe m'zofunikira za VLAN, ndingafunse nonse kuti muyime vidiyoyi, dinani chizindikiro chomwe chili kumanzere kumanzere komwe akuti Networking consultant, pitani ku tsamba lathu la Facebook ndikukonda pamenepo. Kenako bwererani ku kanema ndikudina chizindikiro cha King pakona yakumanja kumanja kuti mulembetse ku njira yathu yovomerezeka ya YouTube. Tikuwonjezera mndandanda watsopano nthawi zonse, tsopano izi zikukhudza maphunziro a CCNA, ndiye tikukonzekera kuyambitsa maphunziro a kanema CCNA Security, Network +, PMP, ITIL, Prince2 ndikusindikiza mndandanda wodabwitsawu pa njira yathu.
Kotero, lero tidzakambirana za zofunikira za VLAN ndikuyankha mafunso atatu: VLAN ndi chiyani, chifukwa chiyani timafunikira VLAN ndi momwe tingayikonzere. Ndikukhulupirira kuti mutatha kuwonera kanemayu mudzatha kuyankha mafunso onse atatu.
VLAN ndi chiyani? VLAN ndi chidule cha maukonde amdera lanu. Pambuyo pake mu phunziroli tiwona chifukwa chake maukondewa ali pafupifupi, koma tisanapite ku VLAN, tiyenera kumvetsetsa momwe kusintha kumagwirira ntchito. Tikambirana ena mwa mafunso omwe takambirana mβmaphunziro apitawa.
Choyamba, tiyeni tikambirane kuti Multiple Collision Domain ndi chiyani. Tikudziwa kuti 48-port switch iyi ili ndi madera 48 ogundana. Izi zikutanthauza kuti chilichonse mwa madokowa, kapena zida zolumikizidwa ndi madoko awa, zimatha kulumikizana ndi chipangizo china padoko losiyana popanda kukhudzana.
Madoko onse 48 a switch iyi ndi gawo limodzi la Broadcast Domain. Izi zikutanthauza kuti ngati zida zambiri zilumikizidwa ku madoko angapo ndipo imodzi mwaiwo ikuwulutsa, idzawonekera pamadoko onse omwe zida zotsalazo zimalumikizidwa. Umu ndi momwe switch imagwirira ntchito.
Zimakhala ngati anthu akukhala mβchipinda chimodzi moyandikana, ndipo wina akalankhula mokweza mawu, aliyense ankamva. Komabe, izi sizothandiza konse - anthu akamawonekera m'chipindamo, phokoso limakhala lokulirapo ndipo omwe alipo sadzamvanso wina ndi mnzake. Zomwe zimachitikanso ndi makompyuta - zida zambiri zikalumikizidwa ndi netiweki imodzi, "kufuula" kumakulirakulira, komwe sikulola kulumikizana koyenera kukhazikitsidwa.
Tikudziwa kuti ngati chimodzi mwa zidazi chikugwirizana ndi netiweki ya 192.168.1.0/24, zida zina zonse ndi gawo la maukonde omwewo. Kusinthaku kuyeneranso kulumikizidwa ndi netiweki yokhala ndi adilesi yomweyo ya IP. Koma apa chosinthira, monga chipangizo cha OSI layer 2, chikhoza kukhala ndi vuto. Ngati zida ziwiri zilumikizidwa ku netiweki imodzi, zimatha kulumikizana mosavuta ndi makompyuta a wina ndi mnzake. Tiyerekeze kuti kampani yathu ili ndi "munthu woyipa", wowononga, yemwe ndimujambule pamwambapa. Pansi pake pali kompyuta yanga. Chifukwa chake, ndizosavuta kuti wowonongayo alowe mu kompyuta yanga chifukwa makompyuta athu ndi gawo la maukonde omwewo. Ndilo vuto.
Ngati ndili m'gulu la oyang'anira ndipo munthu watsopanoyu atha kupeza mafayilo pakompyuta yanga, sizingakhale bwino. Zoonadi, kompyuta yanga ili ndi chowotcha moto chomwe chimateteza ku zowopseza zambiri, koma sizingakhale zovuta kuti wowononga azichilambalala.
Choopsa chachiwiri chomwe chilipo kwa aliyense yemwe ali membala wa tsamba lowulutsali ndikuti ngati wina ali ndi vuto ndi kuwulutsa, kusokonezako kumakhudza zida zina pamaneti. Ngakhale madoko onse a 48 amatha kulumikizidwa ndi makamu osiyanasiyana, kulephera kwa gulu limodzi kumakhudza ena 47, zomwe sizomwe timafunikira.
Kuti tithetse vutoli timagwiritsa ntchito lingaliro la VLAN, kapena netiweki yapafupi. Zimagwira ntchito mophweka kwambiri, kugawa chosinthira chimodzi chachikulu chokhala ndi madoko 48 kukhala masiwichi ang'onoang'ono angapo.
Tikudziwa kuti ma subnets amagawa netiweki imodzi yayikulu kukhala maukonde angapo ang'onoang'ono, ndipo ma VLAN amagwira ntchito mofananamo. Imagawaniza 48-port switch, mwachitsanzo, mu masinthidwe 4 a madoko 12, omwe ali gawo la netiweki yatsopano yolumikizidwa. Nthawi yomweyo, titha kugwiritsa ntchito madoko a 12 oyang'anira, ma doko 12 a IP telephony, ndi zina zotero, ndiye kuti, kugawaniza kusinthana osati mwakuthupi, koma momveka, pafupifupi.
Ndidapereka madoko atatu abuluu pa switch yapamwamba pa netiweki ya buluu ya VLAN10, ndikuyika madoko atatu alalanje a VLAN20. Chifukwa chake, magalimoto aliwonse ochokera kumodzi mwa madoko abuluu awa amangopita ku madoko ena abuluu, osakhudza madoko ena a switch iyi. Magalimoto ochokera kumadoko alalanje adzagawidwa mofanana, ndiye kuti, zimakhala ngati tikugwiritsa ntchito masiwichi awiri osiyana. Chifukwa chake, VLAN ndi njira yogawa ma switch kukhala ma switch angapo pamaneti osiyanasiyana.
Ndinajambula masiwichi awiri pamwamba, apa tili ndi vuto pomwe kumanzere kumanzere kumangolumikizana ndi madoko abuluu a netiweki imodzi, ndipo kumanja - madoko alalanje okha pa netiweki ina, ndipo masiwichi awa samalumikizidwa mwanjira iliyonse. .
Tiyerekeze kuti mukufuna kugwiritsa ntchito madoko ambiri. Tiyerekeze kuti tili ndi nyumba 2, iliyonse ili ndi antchito ake, ndipo madoko awiri alalanje a switch yapansi amagwiritsidwa ntchito poyang'anira. Chifukwa chake, tifunika madoko awa kuti agwirizane ndi madoko onse alalanje a masiwichi ena. Zomwe zilili ndizofanana ndi madoko abuluu - madoko onse abuluu osinthira chakumtunda ayenera kulumikizidwa ndi madoko ena amtundu wofananira. Kuti tichite izi, tifunika kulumikiza masiwichi awiriwa m'nyumba zosiyanasiyana ndi mzere wolumikizana wosiyana; pachithunzichi, ndiye mzere pakati pa madoko awiri obiriwira. Monga tikudziwira, ngati zosintha ziwiri zikugwirizana ndi thupi, timapanga msana, kapena thunthu.
Kodi pali kusiyana kotani pakati pa chosinthira chokhazikika ndi VLAN? Sikusiyana kwakukulu. Mukagula chosinthira chatsopano, mwachisawawa madoko onse amapangidwa mu VLAN mode ndipo ndi gawo la netiweki yomweyo, yosankhidwa VLAN1. Ichi ndichifukwa chake tikalumikiza chipangizo chilichonse ku doko limodzi, chimatha kulumikizidwa ndi madoko ena onse chifukwa madoko onse 48 ndi a VLAN1 yomweyo. Koma ngati tikonza madoko abuluu kuti agwire ntchito pa netiweki ya VLAN10, madoko alalanje pa netiweki ya VLAN20, ndi madoko obiriwira pa VLAN1, tipeza masiwichi atatu osiyanasiyana. Chifukwa chake, kugwiritsa ntchito mawonekedwe a netiweki kumatilola kugawa madoko kukhala maukonde enieni, kugawa zowulutsa m'magawo, ndikupanga ma subnets. Pankhaniyi, madoko aliwonse amtundu winawake amakhala amtundu wosiyana. Ngati madoko a buluu amagwira ntchito pa netiweki ya 3 ndipo madoko a lalanje amagwira ntchito pa netiweki ya 192.168.1.0, ndiye kuti ngakhale adilesi ya IP imodzimodzi, sangalumikizidwe wina ndi mnzake, chifukwa momveka bwino adzakhala a masiwichi osiyanasiyana. Ndipo monga tikudziwira, masiwichi osiyanasiyana akuthupi samalumikizana wina ndi mnzake pokhapokha atalumikizidwa ndi chingwe cholumikizira wamba. Chifukwa chake timapanga ma subnet osiyanasiyana a VLAN osiyanasiyana.
Ndikufuna kukuwonetsani kuti lingaliro la VLAN limagwira ntchito pazosintha zokha. Aliyense amene amadziwa ma encapsulation protocols monga .1Q kapena ISL amadziwa kuti ma routers kapena makompyuta alibe ma VLAN. Mukalumikiza kompyuta yanu, mwachitsanzo, ku imodzi mwamadoko abuluu, simusintha chilichonse pakompyuta; zosintha zonse zimachitika pamlingo wachiwiri wa OSI, mulingo wosinthira. Tikakonza madoko kuti azigwira ntchito ndi netiweki ya VLAN10 kapena VLAN20, kusinthaku kumapanga database ya VLAN. "Imalemba" m'chikumbukiro chake kuti madoko 1,3 ndi 5 ndi a VLAN10, madoko 14,15 ndi 18 ndi gawo la VLAN20, ndipo madoko otsala omwe akukhudzidwa ndi gawo la VLAN1. Chifukwa chake, ngati magalimoto ena amachokera ku doko la buluu 1, amangopita ku madoko 3 ndi 5 a VLAN10 yomweyo. Kusinthaku kumayang'ana nkhokwe yake ndikuwona kuti ngati magalimoto abwera kuchokera kumodzi mwamadoko alalanje, ayenera kupita kumadoko alalanje a VLAN20.
Komabe, kompyuta sadziwa kanthu za VLANs awa. Tikalumikiza masiwichi a 2, thunthu limapangidwa pakati pa madoko obiriwira. Mawu oti "thunthu" ndioyenera pazida za Cisco zokha; opanga zida zina zapaintaneti, monga Juniper, amagwiritsa ntchito mawu akuti Tag port, kapena "doko lodziwika". Ndikuganiza kuti dzina la Tag port ndiloyenera kwambiri. Magalimoto akayamba kuchokera pa netiweki iyi, thunthu limatumiza ku madoko onse a switch yotsatira, ndiye kuti, timalumikiza ma switch awiri a 48-port ndikupeza chosinthira chimodzi cha 96-port. Nthawi yomweyo, tikatumiza magalimoto kuchokera ku VLAN10, imayikidwa chizindikiro, ndiye kuti, imaperekedwa ndi chizindikiro chomwe chikuwonetsa kuti chimangopangidwira madoko a netiweki ya VLAN10. Kusintha kwachiwiri, atalandira magalimotowa, amawerenga chizindikirocho ndikumvetsetsa kuti awa ndi magalimoto makamaka pa netiweki ya VLAN10 ndipo ayenera kupita kumadoko abuluu okha. Momwemonso, magalimoto a "lalanje" a VLAN20 adayikidwa kuti asonyeze kuti akupita ku madoko a VLAN20 pa switch yachiwiri.
Tinatchulanso encapsulation ndipo apa pali njira ziwiri za encapsulation. Yoyamba ndi .1Q, ndiko kuti, pamene tikukonzekera thunthu, tiyenera kupereka encapsulation. Protocol ya .1Q encapsulation ndi muyezo wotseguka womwe umafotokoza njira yolembera ma tag traffic. Palinso protocol ina yotchedwa ISL, Inter-Switch link, yopangidwa ndi Cisco, yomwe imasonyeza kuti magalimoto ndi a VLAN yeniyeni. Zosintha zonse zamakono zimagwira ntchito ndi .1Q protocol, kotero pamene mutenga kusintha kwatsopano m'bokosi, simukusowa kugwiritsa ntchito malamulo a encapsulation, chifukwa mwachisawawa amachitidwa ndi .1Q protocol. Chifukwa chake, mutatha kupanga thunthu, kusungitsa magalimoto kumachitika zokha, zomwe zimalola kuti ma tag awerengedwe.
Tsopano tiyeni tiyambe kukhazikitsa VLAN. Tiyeni tipange maukonde momwe padzakhala zosintha ziwiri ndi zida ziwiri zomaliza - makompyuta PC2 ndi PC1, zomwe tidzalumikiza ndi zingwe kuti tisinthe # 2. Tiyeni tiyambe ndi zoikamo za Basic Configuration switch.
Kuti muchite izi, dinani pa chosinthira ndikupita ku mawonekedwe a mzere wa lamulo, ndiyeno ikani dzina la wolandirayo, ndikuyitcha switch iyi sw1. Tsopano tiyeni tipitirire ku zoikamo za kompyuta yoyamba ndikuyika adilesi ya IP yokhazikika 192.168.1.1 ndi subnet mask 255.255. 255.0. Palibe chifukwa chokhala ndi adilesi yolowera pachipata chifukwa zida zathu zonse zili pa netiweki yomweyo. Kenako, tidzachitanso chimodzimodzi pakompyuta yachiwiri, ndikuipatsa adilesi ya IP 192.168.1.2.
Tsopano tiyeni tibwerere ku kompyuta yoyamba kuti ping yachiwiri kompyuta. Monga mukuwonera, ping idachita bwino chifukwa makompyuta onsewa amalumikizidwa ndi chosinthira chimodzi ndipo ndi gawo la netiweki yomweyo mwa VLAN1. Ngati tsopano tiyang'ana mawonekedwe osinthira, tiwona kuti madoko onse a FastEthernet kuchokera ku 1 mpaka 24 ndi madoko awiri a GigabitEthernet amakonzedwa pa VLAN #1. Komabe, kupezeka kotereku sikofunikira, chifukwa chake timalowa pazosintha ndikulowetsa lamulo la vlan kuti tiyang'ane pankhokwe yapaintaneti.
Mukuwona apa dzina la netiweki ya VLAN1 komanso kuti madoko onse osinthira ndi a netiweki iyi. Izi zikutanthauza kuti mutha kulumikizana ndi doko lililonse ndipo onse azitha "kulankhulana" wina ndi mnzake chifukwa ali gawo la maukonde omwewo.
Tisintha izi; kuti tichite izi, tiyamba kupanga maukonde awiri enieni, ndiye kuti, onjezani VLAN10. Kuti mupange netiweki yeniyeni, gwiritsani ntchito lamulo ngati "vlan network number".
Monga mukuwonera, poyesa kupanga netiweki, makinawo adawonetsa uthenga wokhala ndi mndandanda wamalamulo osintha a VLAN omwe akuyenera kugwiritsidwa ntchito pochita izi:
tulukani - gwiritsani ntchito zosintha ndikutuluka;
dzina - lowetsani dzina la VLAN;
ayi - kuletsa lamulo kapena kuliyika ngati lokhazikika.
Izi zikutanthauza kuti musanalowe pakupanga lamulo la VLAN, muyenera kulowa dzina la lamulo, lomwe limatsegula njira yoyang'anira dzina, ndiyeno pitilizani kupanga netiweki yatsopano. Pankhaniyi, dongosolo limapangitsa kuti nambala ya VLAN igawidwe kuyambira 1 mpaka 1005.
Kotero tsopano tikulowetsa lamulo lopanga VLAN nambala 20 - vlan 20, ndiyeno tipatseni dzina la wogwiritsa ntchito, lomwe limasonyeza mtundu wa maukonde. Kwa ife, timagwiritsa ntchito dzina la Employees command, kapena network ya ogwira ntchito pakampani.
Tsopano tikufunika kupatsa doko linalake ku VLAN iyi. Timalowetsa masinthidwe osinthira int f0/1, kenaka sinthani pamanja doko kupita ku Njira Yofikira pogwiritsa ntchito njira yolumikizira ma switchport ndikuwonetsa kuti ndi doko liti lomwe liyenera kusinthidwa kukhala njira iyi - iyi ndiye doko la netiweki ya VLAN10.
Tikuwona kuti zitatha izi mtundu wa malo olumikizirana pakati pa PC0 ndi chosinthira, mtundu wa doko, wasintha kuchokera ku zobiriwira kupita ku lalanje. Idzakhalanso yobiriwira pomwe zosintha zikayamba kugwira ntchito. Tiyeni tiyese ping yachiwiri kompyuta. Sitinasinthe makonzedwe a netiweki pamakompyuta, akadali ndi ma adilesi a IP a 192.168.1.1 ndi 192.168.1.2. Koma ngati tiyesa kuyimba PC0 kuchokera pa kompyuta PC1, palibe chomwe chingagwire ntchito, chifukwa tsopano makompyutawa ali amitundu yosiyanasiyana: yoyamba ku VLAN10, yachiwiri kwa VLAN1.
Tiyeni tibwerere ku mawonekedwe osinthira ndikukonzekera doko lachiwiri. Kuti ndichite izi, ndipereka lamulo int f0/2 ndikubwereza masitepe omwewo a VLAN 20 monga ndidachitira pokonza maukonde am'mbuyomu.
Tikuwona kuti tsopano doko lapansi la chosinthira, chomwe kompyuta yachiwiri imalumikizidwa, yasinthanso mtundu wake kuchokera ku zobiriwira kupita ku lalanje - masekondi angapo ayenera kudutsa zisanachitike kusintha kwa zoikamo ndikutembenukiranso zobiriwira. Ngati tiyambiranso kuyimbanso kompyuta yachiwiri, palibe chomwe chingagwire ntchito, chifukwa makompyuta akadali a maukonde osiyanasiyana, PC1 yokha ndi gawo la VLAN1, osati VLAN20.
Chifukwa chake, mwagawa kusinthana kumodzi kukhala masiwichi awiri osiyana. Mukuwona kuti mtundu wa doko tsopano wasintha kuchokera ku lalanje kupita ku wobiriwira, doko likugwira ntchito, komabe siliyankha chifukwa ndi la intaneti yosiyana.
Tiyeni tisinthe madera athu - chotsani kompyuta PC1 kuchokera pa switch yoyamba ndikuyilumikiza ku chosinthira chachiwiri, ndikulumikiza ma switch okha ndi chingwe.
Kuti ndikhazikitse kulumikizana pakati pawo, ndipita pazosintha zachiwiri ndikupanga VLAN10, ndikuyitcha kuti Management, ndiko kuti, network yoyang'anira. Kenako nditsegula mawonekedwe a Access ndikulongosola kuti njirayi ndi ya VLAN10. Tsopano mtundu wa madoko omwe masiwichi amalumikizidwa nawo wasintha kuchokera ku lalanje kupita ku wobiriwira chifukwa onse amapangidwa pa VLAN10. Tsopano tifunika kupanga thunthu pakati pa masiwichi onse awiri. Madoko onsewa ndi Fa0 / 2, kotero muyenera kupanga thunthu la Fa0 / 2 doko la switch yoyamba pogwiritsa ntchito switchport mode trunk command. Zomwezo ziyenera kuchitika pakusintha kwachiwiri, kenako thunthu limapangidwa pakati pa madoko awiriwa.
Tsopano, ngati ndikufuna ping PC1 kuchokera pa kompyuta yoyamba, chirichonse chidzayenda bwino, chifukwa kugwirizana pakati pa PC0 ndi kusintha # 0 ndi VLAN10 network, pakati pa lophimba #1 ndi PC1 ndi VLAN10, ndipo masiwichi onse olumikizidwa ndi thunthu. .
Chifukwa chake, ngati zida zili pa VLAN zosiyanasiyana, ndiye kuti sizilumikizidwa, koma ngati zili pamaneti omwewo, ndiye kuti magalimoto amatha kusinthanitsa mwaulere pakati pawo. Tiyeni tiyese kuwonjezera chipangizo chimodzi pa switch iliyonse.
Mu zoikamo maukonde kompyuta anawonjezera PC2, ine adzaika IP adiresi 192.168.2.1, ndi zoikamo PC3, adiresi adzakhala 192.168.2.2. Pankhaniyi, madoko omwe ma PC awiriwa amalumikizidwa adzasankhidwa Fa0/3. Muzokonda zosinthira #0 tidzakhazikitsa Njira Yofikira ndikuwonetsa kuti dokoli ndi la VLAN20, ndipo tidzachitanso chimodzimodzi pakusintha #1.
Ngati ndigwiritsa ntchito switchport access vlan 20 command, ndipo VLAN20 sinapangidwebe, dongosololi liwonetsa cholakwika ngati "Access VLAN kulibe" chifukwa masiwichi amakonzedwa kuti azigwira ntchito ndi VLAN10 yokha.
Tiyeni tipange VLAN20. Ndimagwiritsa ntchito lamulo la "show VLAN" kuti ndiwone zomwe zili pa intaneti.
Mutha kuwona kuti netiweki yosasinthika ndi VLAN1, komwe madoko Fa0/4 mpaka Fa0/24 ndi Gig0/1, Gig0/2 alumikizidwa. VLAN nambala 10, yotchedwa Management, yolumikizidwa ku doko Fa0/1, ndipo VLAN nambala 20, yotchedwa VLAN0020 mwachisawawa, imalumikizidwa ndi doko Fa0/3.
M'malo mwake, dzina la intaneti lilibe kanthu, chinthu chachikulu ndikuti sichibwerezedwanso pamaneti osiyanasiyana. Ngati ndikufuna kusintha dzina la intaneti lomwe dongosolo limapereka mwachisawawa, ndimagwiritsa ntchito vlan 20 ndi dzina la Ogwira ntchito. Ndikhoza kusintha dzina ili ku chinthu china, monga ma IPphone, ndipo ngati tiyimba adilesi ya IP 192.168.2.2, tikhoza kuona kuti dzina la VLAN liribe tanthauzo.
Chinthu chotsiriza chimene ndikufuna kutchula ndi cholinga cha Management IP, chomwe tinakambirana m'phunziro lapitali. Kuti tichite izi timagwiritsa ntchito int vlan1 lamulo ndikulowetsa adilesi ya IP 10.1.1.1 ndi subnet mask 255.255.255.0 ndikuwonjezera lamulo loletsa kutseka. Tidapereka Management IP osati pakusintha konse, koma madoko a VLAN1 okha, ndiye kuti, tidapereka adilesi ya IP komwe network ya VLAN1 imayendetsedwa. Ngati tikufuna kuyang'anira VLAN2, tiyenera kupanga mawonekedwe ofanana a VLAN2. Kwa ife, pali madoko a buluu a VLAN10 ndi madoko a lalanje a VLAN20, omwe amafanana ndi ma adilesi 192.168.1.0 ndi 192.168.2.0.
VLAN10 iyenera kukhala ndi ma adilesi omwe ali mumtundu womwewo kuti zida zoyenera zitha kulumikizana nazo. Makonzedwe ofananawo ayenera kupangidwira VLAN20.
Zenera la mzere wosinthirawu likuwonetsa mawonekedwe a VLAN1, ndiye kuti, VLAN yakubadwa.
Kuti tikonze Management IP ya VLAN10, tiyenera kupanga mawonekedwe int vlan 10, ndikuwonjezera adilesi ya IP 192.168.1.10 ndi subnet mask 255.255.255.0.
Kukonza VLAN20, tiyenera kupanga mawonekedwe int vlan 20, ndiyeno kuwonjezera IP adiresi 192.168.2.10 ndi subnet chigoba 255.255.255.0.
Nβchifukwa chiyani zimenezi zili zofunika? Ngati kompyuta PC0 ndi doko chapamwamba kumanzere kwa lophimba #0 ndi 192.168.1.0 netiweki, PC2 ndi 192.168.2.0 maukonde ndipo chikugwirizana ndi mbadwa VLAN1 doko, amene ali 10.1.1.1 netiweki, ndiye PC0 sangathe kukhazikitsa kulumikizana ndi switch iyi kudzera pa protocol SSH chifukwa ndi ya ma network osiyanasiyana. Chifukwa chake, kuti PC0 ilumikizane ndi switch kudzera pa SSH kapena Telnet, tiyenera kuyipatsa mwayi wofikira. Ichi ndichifukwa chake timafunikira kasamalidwe ka maukonde.
Tiyenera kumanga PC0 pogwiritsa ntchito SSH kapena Telnet ku adilesi ya IP ya VLAN20 ndikupanga kusintha kulikonse komwe tingafune kudzera pa SSH. Chifukwa chake, Management IP ndiyofunikira makamaka pakukonza ma VLAN, chifukwa netiweki iliyonse iyenera kukhala ndi njira yake yolowera.
Mu kanema wamasiku ano, tidakambirana zambiri: zosintha zoyambira, kupanga ma VLAN, kugawa madoko a VLAN, kugawa Management IP kwa ma VLAN, ndikusintha mitengo ikuluikulu. Musachite manyazi ngati simukumvetsa chinachake, izi ndi zachilengedwe, chifukwa VLAN ndi nkhani yovuta kwambiri komanso yotakata yomwe tidzabwereranso m'maphunziro amtsogolo. Ndikukutsimikizirani kuti ndi chithandizo changa mutha kukhala mbuye wa VLAN, koma mfundo ya phunziroli inali kukufotokozerani mafunso atatu: ma VLAN ndi chiyani, chifukwa chiyani timawafuna komanso momwe tingawakhazikitsire.
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).
