Hnub no kuv yuav qhia koj yuav ua li cas npaj lub network hauv ib lub tuam txhab me me. Peb tau mus txog ib theem ntawm kev cob qhia rau kev hloov pauv - hnub no peb yuav muaj cov yeeb yaj kiab kawg, xaus lub ntsiab lus ntawm Cisco keyboards. Tau kawg, peb yuav rov qab mus rau cov kev hloov pauv, thiab hauv zaj lus qhia video tom ntej no kuv yuav qhia koj txog daim ntawv qhia txoj kev kom txhua tus nkag siab tias peb tab tom txav mus rau qhov twg thiab qhov twg peb tau kawm tiav.
Hnub 18 ntawm peb cov chav kawm yuav yog qhov pib ntawm lub ncauj lus tshiab rau cov routers, thiab kuv yuav mob siab rau zaj lus qhia tom ntej, Hnub 17, rau kev tshuaj xyuas cov ncauj lus kawm thiab tham txog cov phiaj xwm rau kev cob qhia ntxiv. Ua ntej peb nkag mus rau lub ntsiab lus qhia hnub no, Kuv xav kom koj nco ntsoov muab cov yeeb yaj kiab no, sau npe rau peb channel YouTube, mus saib peb pawg Facebook thiab lub vev xaib , qhov twg koj tuaj yeem nrhiav cov lus tshaj tawm ntawm cov lus qhia tshiab.
Yog li cia peb pib tsim lub chaw ua haujlwm network. Yog tias koj rhuav tshem cov txheej txheem no mus rau hauv qhov chaw, thawj qhov koj yuav tsum tau ua yog xam cov kev cai uas lub network no yuav tsum txaus siab. Yog li ua ntej koj pib tsim lub network rau lub chaw ua haujlwm me me, hauv tsev network lossis lwm lub network hauv zos, koj yuav tsum tau ua ib daim ntawv teev cov cai rau nws.
Qhov thib ob uas yuav tsum tau ua yog tsim lub network tsim, txiav txim siab seb koj npaj yuav ua li cas kom tau raws li qhov yuav tsum tau ua, thiab qhov thib peb yog los tsim lub cev kev teeb tsa ntawm lub network.
Piv txwv li peb tab tom tham txog ib lub chaw ua haujlwm tshiab uas muaj ntau lub tuam tsev: Kev Lag Luam Kev Lag Luam, Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas, Lub Tuam Txhab Nyiaj Txiag Nyiaj Txiag, Lub Chaw Pabcuam Tib Neeg thiab Chav Ua Haujlwm, nyob rau hauv uas koj yuav nyob hauv IT kev txhawb nqa tshwj xeeb thiab tus thawj tswj hwm. Tom ntej no yog chav muag khoom.
Cov kev cai rau lub network tsim yog tias cov neeg ua haujlwm ntawm cov tuam tsev sib txawv yuav tsum tsis txhob txuas rau ib leeg. Qhov no txhais tau hais tias, piv txwv li, cov neeg ua haujlwm ntawm lub chaw muag khoom nrog 7 lub khoos phis tawj tuaj yeem hloov pauv cov ntaub ntawv thiab cov lus sib tham hauv lub network. Ib yam li ntawd, ob lub khoos phis tawj hauv chav ua lag luam tsuas tuaj yeem sib txuas lus nrog ib leeg. Lub chaw tswj hwm, uas muaj 1 lub computer, yav tom ntej yuav nthuav dav rau ntau tus neeg ua haujlwm. Ib yam li ntawd, lub tuam txhab nyiaj txiag thiab cov neeg ua haujlwm pabcuam yuav tsum muaj lawv tus kheej sib cais.
Cov no yog cov kev cai rau peb lub network. Raws li kuv tau hais, chav neeg rau zaub mov yog chav uas koj yuav zaum thiab los ntawm qhov chaw koj yuav txhawb nqa tag nrho cov chaw ua haujlwm network. Txij li qhov no yog lub network tshiab, koj tuaj yeem xaiv nws qhov kev teeb tsa thiab yuav npaj li cas. Ua ntej peb mus ntxiv, kuv xav qhia koj seb chav server zoo li cas.
Nws yog nyob ntawm koj, raws li tus thawj tswj hwm network, seb koj chav neeg rau zaub mov yuav zoo li qhov pom ntawm thawj tus swb lossis ib qho uas pom nyob rau zaum ob.
Qhov sib txawv ntawm ob lub servers no nyob ntawm seb koj muaj kev qhuab ntuas li cas. Yog tias koj ua raws li kev coj ua ntawm kev sau npe network cables nrog cov cim npe thiab cov ntawv nplaum, koj tuaj yeem khaws koj lub chaw ua haujlwm hauv kev sib txuas. Raws li koj tau pom, nyob rau hauv lub thib ob neeg rau zaub mov chav tsev tag nrho cov cables nyob rau hauv kev txiav txim thiab txhua pab pawg neeg ntawm cables yog txawm peem rau nrog ib tug tag uas qhia qhov twg cov cables mus. Piv txwv li, ib lub cable mus rau lub chaw muag khoom, lwm qhov mus rau kev tswj hwm, thiab lwm yam, uas yog, txhua yam tau txheeb xyuas.
Koj tuaj yeem ua ib chav neeg rau zaub mov raws li qhia hauv thawj tus swb yog tias koj tsuas muaj 10 lub khoos phis tawj xwb. Koj tuaj yeem lo cables hauv qhov kev txiav txim tsis sib xws thiab npaj cov keyboards yam tsis muaj qhov system hauv lawv qhov kev npaj. Qhov no tsis yog teeb meem tsuav koj muaj lub network me me. Tab sis raws li ntau lub khoos phis tawj tau ntxiv thiab lub tuam txhab network nthuav dav, yuav muaj lub ntsiab lus uas koj yuav siv sijhawm feem ntau txheeb xyuas tag nrho cov cables. Tej zaum koj yuav txiav ib lub cable mus rau lub computer lossis tsuas yog tsis nkag siab tias cable txuas rau qhov chaw nres nkoj twg.
Yog li, lub koom haum ntse ntawm kev npaj cov khoom siv hauv koj chav neeg rau zaub mov yog qhov koj nyiam tshaj plaws. Tom ntej no tseem ceeb tshaj plaws los tham txog yog kev txhim kho network - cables, plugs thiab cables. Peb tham ntau txog cov keyboards, tab sis tsis nco qab tham txog cables.
Ib qho CAT5 lossis CAT6 cable feem ntau hu ua ib qho tsis muaj kev sib tw twisted lossis UTP cable. Yog hais tias koj tshem tawm cov ntaub thaiv npog ntawm xws li ib tug cable, koj yuav pom 8 xov hlau twisted ua khub: ntsuab thiab dawb-ntsuab, txiv kab ntxwv thiab dawb-txiv kab ntxwv, xim av thiab dawb-xim av, xiav thiab dawb-xiav. Vim li cas lawv twist? Electromagnetic cuam tshuam ntawm cov teeb liab hluav taws xob nyob rau hauv ob qho tib si nyob ntawm cov xaim hluav taws xob tsim suab nrov, uas ua rau lub teeb liab tsis muaj zog thaum cov xov hlau ntev ntev. Twisting cov xov hlau sib koom ua ke them nyiaj rau qhov tshwm sim induced tam sim no, txo kev cuam tshuam thiab ua rau kom lub teeb liab sib kis.
Peb muaj 6 pawg ntawm lub network cable - los ntawm 1 mus rau 6. Raws li qeb nce, lub teeb liab kis tau tus mob nyob ntawm qhov nce, feem ntau yog vim lub fact tias cov degree ntawm twisting ntawm cov khub nce. CAT6 cable muaj ntau qhov kev hloov pauv ntawm ib chav tsev ntev dua li CAT5, yog li nws kim dua. Raws li, Qeb 6 cables muab ntau dua cov ntaub ntawv hloov ceev tshaj qhov ntev dua. Cov kab hluav taws xob ntau tshaj plaws ntawm kev ua lag luam yog 5, 5e thiab 6. 5e cable yog ib qho kev txhim kho qib 5, nws yog siv los ntawm cov tuam txhab feem ntau, tab sis thaum tsim cov chaw ua haujlwm niaj hnub no lawv tsuas yog siv CAT6.
Yog hais tias koj strip no cable ntawm nws sheath nws yuav muaj 4 twisted khub raws li qhia nyob rau hauv lub swb. Koj kuj muaj RJ-45 connector uas muaj 8 tus pins hlau. Koj yuav tsum tau ntxig cov hlua cable rau hauv qhov txuas thiab siv lub cuab yeej crimping hu ua crimper. Yuav kom crimp twisted khub xov hlau, koj yuav tsum paub yuav ua li cas muab lawv kom raug nyob rau hauv lub connector. Cov txheej txheem hauv qab no yog siv rau qhov no.
Muaj ncaj qha thiab crossover, los yog crossover crimping ntawm twisted khub cables. Hauv thawj kis, koj txuas cov xov hlau ntawm tib xim rau ib leeg, uas yog, koj txuas cov hlau dawb-txiv kab ntxwv mus rau 1 tus pin ntawm RJ-45 connector, txiv kab ntxwv ib mus rau ob, cov xaim dawb-ntsuab mus rau. thib peb thiab lwm yam, raws li qhia hauv daim duab.
Feem ntau, yog tias koj txuas 2 yam khoom sib txawv, piv txwv li, hloov thiab lub hub lossis hloov thiab router, koj siv ncaj qha crimping. Yog tias koj xav txuas cov khoom siv zoo ib yam, piv txwv li kev hloov mus rau lwm qhov hloov, koj yuav tsum siv crossover. Nyob rau hauv ob qho tib si, ib tug hlau ntawm tib xim yog txuas nrog ib tug hlau ntawm tib xim; koj tsuas yog hloov cov txheeb ze txoj hauj lwm ntawm cov xov hlau thiab connector pins.
Kom nkag siab qhov no, xav txog xov tooj. Koj hais lus rau hauv lub xov tooj lub microphone thiab mloog lub suab ntawm tus hais lus. Yog tias koj tham nrog koj tus phooj ywg, qhov koj hais rau hauv lub microphone los ntawm nws lub xov tooj tus neeg hais lus, thiab qhov koj tus phooj ywg hais rau hauv nws lub microphone tawm ntawm koj tus neeg hais lus.
Qhov no yog qhov crossover kev twb kev txuas. Yog tias koj txuas koj lub microphones ua ke thiab txuas koj cov neeg hais lus, cov xov tooj yuav tsis ua haujlwm. Qhov no tsis yog qhov kev sib piv zoo tshaj plaws, tab sis kuv vam tias koj yuav tau txais lub tswv yim ntawm kev sib tw: cov xaim xaim mus rau cov xaim xaim, thiab cov xaim xaim mus rau lub receiver.
Kev sib txuas ncaj qha ntawm cov khoom siv sib txawv ua haujlwm zoo li no: qhov hloov pauv thiab lub router muaj cov chaw nres nkoj sib txawv, thiab yog tias tus pins 1 thiab 2 ntawm qhov hloov pauv tau npaj rau kev sib kis, ces pins 1 thiab 2 ntawm lub router yog npaj rau kev txais. Yog tias cov khoom siv zoo ib yam, ces kev sib cuag 1 thiab 2 ntawm ob qho tib si thawj thiab thib ob hloov pauv tau siv rau kev sib kis, thiab txij li cov xaim xaim tsis tuaj yeem txuas nrog tib cov xov hlau, kev sib cuag 1 thiab 2 ntawm lub tshuab xa hluav taws xob ntawm thawj tus hloov pauv txuas nrog. tiv tauj 3 thiab 6 ntawm qhov hloov thib ob, uas yog, nrog tus txais. Qhov ntawd yog qhov crossover yog rau.
Tab sis niaj hnub no cov tswv yim no yog outdated, es tsis txhob Auto-MDIX yog siv - cov ntaub ntawv hloov chaw interface uas nyob ntawm ib puag ncig. Koj tuaj yeem paub txog nws los ntawm Google lossis Wikipedia tsab xov xwm, Kuv tsis xav nkim sijhawm rau qhov ntawd. Nyob rau hauv luv luv, qhov no hluav taws xob thiab mechanical interface tso cai rau koj siv tej cable, xws li ib tug ncaj qha kev twb kev txuas, thiab lub ntse ntaus ntawv nws tus kheej yuav txiav txim siab seb hom ntawm cable yog siv - ib tug transmitter los yog ib tug receiver, thiab txuas nws raws li.
Tam sim no peb tau saib yuav ua li cas cables yuav tsum tau txuas nrog, cia peb mus rau lub network tsim cov cai. Cia peb qhib Cisco Packet Tracer thiab pom tias kuv tau muab cov duab kos ntawm peb lub chaw ua haujlwm ua lub substrate rau txheej saum toj kawg nkaus ntawm kev txhim kho network. Txij li cov tuam tsev sib txawv muaj cov tes hauj lwm sib txawv, nws yog qhov zoo tshaj los npaj lawv los ntawm kev ywj pheej hloov. Kuv yuav tso ib qho kev hloov pauv hauv txhua chav, yog li peb muaj tag nrho ntawm rau lub hloov pauv ntawm SW0 txog SW5. Tom qab ntawd kuv yuav npaj 1 lub computer rau txhua tus neeg ua haujlwm hauv chaw ua haujlwm - tag nrho ntawm 12 daim ntawm PC0 txog PC11. Tom qab ntawd, kuv yuav txuas txhua lub khoos phis tawj mus rau qhov hloov pauv siv lub cable. Qhov kev npaj no muaj kev ruaj ntseg zoo, ib lub tuam tsev cov ntaub ntawv tsis tuaj yeem nkag mus rau lwm lub tuam tsev, koj tsis muaj kev paub txog lwm lub tuam tsev ua tiav lossis tsis ua tiav, thiab nws yog txoj cai hauv chaw ua haujlwm zoo. Tej zaum ib tug neeg hauv lub tuam tsev muag khoom muaj kev txawj nyiag nkas thiab tuaj yeem nkag mus rau hauv lub tuam txhab lag luam cov khoos phis tawj hauv kev sib koom tes thiab tshem tawm cov ntaub ntawv, lossis cov neeg nyob hauv ntau lub tuam tsev tsuas yog yuav tsum tsis txhob muab cov ntaub ntawv rau kev lag luam, thiab lwm yam, yog li cais cov tes hauj lwm pab tiv thaiv cov xwm txheej zoo sib xws. .
Qhov teeb meem yog qhov no. Kuv mam li ntxiv huab rau hauv qab ntawm daim duab - qhov no yog Is Taws Nem, uas tus thawj tswj hwm lub khoos phis tawj network hauv chav server txuas nrog los ntawm kev hloov.
Koj tsis tuaj yeem muab txhua chav haujlwm rau ib tus neeg nkag mus rau Is Taws Nem, yog li koj yuav tsum txuas cov chaw hloov pauv mus rau qhov hloov pauv hauv chav server. Qhov no yog raws nraim li qhov yuav tsum tau ua rau kev sib txuas hauv chaw ua haujlwm hauv Is Taws Nem zoo li - txhua tus neeg siv khoom siv yuav tsum txuas mus rau ib qho kev hloov pauv uas muaj kev nkag mus sab nraum chaw ua haujlwm network.
Ntawm no peb muaj ib qho teeb meem uas paub zoo: yog tias peb tawm hauv lub network nrog kev teeb tsa tsis raug, ces txhua lub khoos phis tawj yuav muaj peev xwm sib txuas lus vim tias lawv yuav txuas nrog tib haiv neeg VLAN1. Txhawm rau zam qhov no, peb yuav tsum tsim VLANs sib txawv.
Peb yuav ua haujlwm nrog 192.168.1.0/24 network, uas peb yuav faib ua ob peb subnets me. Cia peb pib los ntawm kev tsim lub suab network VLAN10 nrog qhov chaw nyob 192.168.1.0/26. Koj tuaj yeem saib ntawm lub rooj hauv ib qho ntawm cov kev qhia hauv video dhau los thiab qhia kuv tias pes tsawg tus tswv yuav muaj nyob rau hauv lub network no - / 26 txhais tau tias 2 cov khoom qiv uas faib lub network rau 4 feem ntawm 64 chaw nyob, yog li yuav muaj 62 tus IP pub dawb chaw nyob hauv koj lub subnet rau hosts. Peb yuav tsum tsim kom muaj kev sib txuas lus sib txuas lus rau lub suab sib txuas lus los ntawm kev sib txuas lus ntawm cov ntaub ntawv. Qhov no yuav tsum tau ua los tiv thaiv tus neeg tawm tsam los ntawm kev sib txuas nrog kev sib tham hauv xov tooj thiab siv Wireshark los txiav txim siab cov ntaub ntawv xa mus rau tib lub channel raws li lub suab sib txuas lus.
Yog li, VLAN10 tsuas yog siv rau IP xov tooj xwb. A slash 26 txhais tau hais tias 62 lub xov tooj tuaj yeem txuas nrog lub network no. Tom ntej no, peb yuav tsim ib qho chaw tswj xyuas network VLAN20 nrog qhov chaw nyob ntawm 192.168.1.64/27, uas yog, qhov chaw nyob hauv network yuav yog 32 nrog 30 tus tswv tsev IP chaw nyob. VLAN30 yuav raug xa mus rau chav ua lag luam, VLAN40 yuav yog chav muag khoom, VLAN50 yuav yog chav haujlwm nyiaj txiag, VLAN60 yuav yog chav haujlwm HR, thiab VLAN100 yuav yog IT department network.
Cia peb sau cov tes hauj lwm no nyob rau hauv lub chaw ua hauj lwm network topology daim duab thiab pib nrog VLAN20 vim VLAN10 yog tseg rau xov tooj. Tom qab no, peb tuaj yeem xav tias peb tau tsim cov qauv tsim ntawm lub chaw ua haujlwm tshiab.
Yog tias koj nco qab, kuv tau hais tias koj chav neeg rau zaub mov tuaj yeem muaj qhov teeb meem chaotic lossis ua tib zoo npaj. Txawm li cas los xij, koj yuav tsum tsim cov ntaub ntawv - cov no tuaj yeem yog cov ntaub ntawv sau rau ntawm daim ntawv lossis hauv lub computer, uas yuav sau cov qauv ntawm koj lub network, piav qhia tag nrho cov subnets, kev sib txuas, IP chaw nyob thiab lwm yam ntaub ntawv tsim nyog rau kev ua haujlwm ntawm tus thawj tswj hwm network. Nyob rau hauv cov ntaub ntawv no, raws li lub network tsim, koj yuav ib txwm nyob rau hauv kev tswj ntawm qhov teeb meem. Qhov no yuav pab koj txuag lub sijhawm thiab tsis txhob muaj teeb meem thaum txuas cov khoom siv tshiab thiab tsim cov subnets tshiab.
Yog li, tom qab peb tau tsim cais subnets rau txhua chav haujlwm, uas yog, peb tau ua nws kom cov khoom siv tsuas yog sib txuas lus hauv lawv tus kheej VLAN, cov lus nug hauv qab no tshwm sim. Raws li koj nco qab, qhov hloov pauv hauv chav neeg rau zaub mov yog lub hauv paus kev sib txuas lus uas tag nrho lwm cov keyboards txuas nrog, yog li nws yuav tsum paub txog txhua lub network hauv chaw ua haujlwm. Txawm li cas los xij, hloov SW0 tsuas yog xav paub txog VLAN30 vim tias tsis muaj lwm lub network hauv chav haujlwm no. Tam sim no xav txog tias peb lub tuam txhab muag khoom tau nthuav dav thiab peb yuav tau hloov qee tus neeg ua haujlwm mus rau qhov chaw ntawm kev lag luam. Nyob rau hauv cov ntaub ntawv no, peb yuav tsum tau tsim ib tug VLAN40 network nyob rau hauv lub lag luam department, uas kuj yuav tsum tau txuas mus rau lub SW0 hloov.
Hauv ib qho ntawm cov yeeb yaj kiab dhau los, peb tau tham txog dab tsi hu ua kev tswj hwm interface, uas yog, peb tau mus rau VLAN1 interface thiab muab tus IP chaw nyob. Tam sim no peb yuav tsum teeb tsa 2 lub chaw tswj hwm lub khoos phis tawj kom lawv txuas nrog cov chaw nkag nkag ntawm qhov hloov pauv uas sib haum rau VLAN30.
Cia peb saib ntawm koj lub PC7 lub khoos phis tawj, uas koj, ua tus tswj hwm lub network, yuav tsum tswj hwm txhua lub network hloov pauv. Ib txoj hauv kev los xyuas kom meej qhov no yog mus rau lub chaw tswj hwm thiab manually teeb tsa SW0 hloov kom nws txuas nrog koj lub computer. Txawm li cas los xij, koj yuav tsum tuaj yeem teeb tsa qhov kev hloov pauv no nyob deb vim tias kev teeb tsa ntawm qhov chaw tsis tas yuav ua tau. Tab sis koj nyob ntawm VLAN100 vim PC7 txuas nrog VLAN100 hloov chaw nres nkoj.
Hloov SW0 tsis paub dab tsi txog VLAN100, yog li peb yuav tsum muab VLAN100 rau ib qho ntawm nws cov chaw nres nkoj kom PC7 tuaj yeem sib txuas lus nrog nws. Yog tias koj muab VLAN30 IP chaw nyob rau interface SW0, tsuas yog PC0 thiab PC1 tuaj yeem txuas rau nws. Txawm li cas los xij, koj yuav tsum muaj peev xwm tswj tau qhov kev hloov no los ntawm koj lub PC7 lub computer uas yog VLAN100 network. Yog li ntawd, peb yuav tsum tsim ib qho interface rau VLAN0 hauv kev hloov SW100. Peb yuav tsum ua tib yam nrog cov keyboards ntxiv - tag nrho cov khoom siv no yuav tsum muaj VLAN100 interface, uas peb yuav tsum muab tus IP chaw nyob los ntawm ntau qhov chaw nyob siv los ntawm PC7. Qhov chaw nyob no yog muab los ntawm 192.168.1.224/27 ntau yam ntawm IT VLAN thiab raug xa mus rau txhua qhov chaw hloov chaw uas VLAN100 raug muab.
Tom qab no, los ntawm chav neeg rau zaub mov, los ntawm koj lub computer, koj yuav tuaj yeem tiv tauj ib qho ntawm cov keyboards ntawm Telnet raws tu qauv thiab teeb tsa lawv raws li qhov xav tau ntawm lub network. Txawm li cas los xij, raws li tus thawj coj hauv lub network, koj kuj xav tau kev nkag mus rau cov keyboards no ntawm kev sib txuas lus sab nraud, lossis tawm ntawm kev nkag mus. Txhawm rau muab cov kev nkag tau zoo li no, koj xav tau lub cuab yeej hu ua Terminal Server, lossis lub davhlau ya nyob twg server.
Raws li cov laj thawj network topology, tag nrho cov keyboards no nyob rau hauv cov chav sib txawv, tab sis lub cev lawv tuaj yeem ntsia tau rau ntawm cov khib nyiab ntau hauv chav neeg rau zaub mov. Koj tuaj yeem ntxig lub davhlau ya nyob twg rau hauv tib lub khib, uas txhua lub khoos phis tawj yuav txuas nrog. Cov kab hluav taws xob kho qhov muag tawm los ntawm cov neeg rau zaub mov no, ntawm ib kawg ntawm uas muaj Serial connector, thiab nyob rau lwm qhov kawg muaj ib lub ntsaws rau CAT5 cable. Tag nrho cov cables no txuas nrog lub console ports ntawm cov keyboards ntsia hauv khib. Txhua qhov kho qhov muag cable tuaj yeem txuas 8 li. Lub davhlau ya nyob twg server yuav tsum txuas nrog koj lub PC7 lub computer. Yog li, los ntawm Terminal Server koj tuaj yeem txuas mus rau lub console chaw nres nkoj ntawm ib qho ntawm cov keyboards ntawm kev sib txuas lus sab nraud.
Koj tuaj yeem nug yog vim li cas qhov no yog qhov tsim nyog yog tias tag nrho cov khoom siv no nyob ib sab ntawm koj hauv ib chav neeg rau zaub mov. Qhov tseeb yog tias koj lub computer tsuas tuaj yeem txuas ncaj qha mus rau ib qho chaw console. Yog li ntawd, txhawm rau kuaj ntau lub keyboards, koj yuav tsum tau txiav tawm lub cev ntawm ib lub cuab yeej txuas mus rau lwm qhov. Thaum siv lub davhlau ya nyob twg server, koj tsuas yog yuav tsum nias ib tus yuam sij ntawm koj lub khoos phis tawj keyboard kom txuas mus rau lub console chaw nres nkoj ntawm kev hloov # 0, hloov mus rau lwm qhov kev hloov koj tsuas yog yuav tsum nias lwm tus yuam sij, thiab lwm yam. Yog li, koj tuaj yeem tswj tau ib qho ntawm cov keyboards yooj yim los ntawm nias cov yuam sij. Yog li ntawd, nyob rau hauv ib txwm muaj xwm txheej, koj xav tau lub davhlau ya nyob twg server los tswj cov keyboards thaum daws teeb meem network.
Yog li, peb tau ua tiav nrog lub network tsim thiab tam sim no peb yuav saib cov kev teeb tsa hauv network yooj yim.
Txhua yam khoom siv yuav tsum tau muab lub npe hostname, uas koj yuav tsum ua siv cov kab hais kom ua. Kuv vam tias thaum koj ua tiav cov chav kawm no, koj yuav tau txais kev paub siv tau kom koj paub los ntawm lub siab cov lus txib uas xav tau los muab lub npe hostname, tsim ib daim ntawv txais tos, teeb tsa tus password console, teeb tsa Telnet password, thiab ua kom tus password prompting. . Koj yuav tsum paub yuav ua li cas tswj qhov hloov pauv tus IP chaw nyob, muab lub rooj vag qub qub, tswj xyuas lub cuab yeej, nkag mus rau cov lus txib tsis pom zoo, thiab txuag cov kev hloov pauv rau qhov hloov chaw.
Yog tias koj ua tiav tag nrho peb cov kauj ruam: txiav txim siab qhov yuav tsum tau ua rau lub network, kos ib daim duab ntawm lub network yav tom ntej tsawg kawg ntawm daim ntawv thiab tom qab ntawd txav mus rau qhov chaw, koj tuaj yeem yooj yim teeb tsa koj chav neeg rau zaub mov.
Raws li kuv twb tau hais lawm, peb yuav luag tiav kev kawm hloov pauv, txawm hais tias peb yuav rov qab mus rau lawv, yog li hauv cov tshooj video tom ntej peb yuav txav mus rau routers. Qhov no yog ib lub ntsiab lus nthuav heev, uas kuv yuav sim ua kom tag nrho raws li qhov ua tau. Peb yuav saib thawj daim vis dis aus txog routers los ntawm ib zaj lus qhia, thiab zaj lus qhia tom ntej, Hnub 17, Kuv yuav mob siab rau cov txiaj ntsig ntawm kev ua haujlwm ntawm kev kawm CCNA chav kawm, Kuv yuav qhia rau koj tias qhov twg ntawm chav kawm koj tau kawm tiav. thiab ntau npaum li cas koj tseem yuav tau kawm, kom txhua tus neeg nkag siab meej txog theem ntawm kev kawm lawv tau mus txog.
Kuv npaj yuav tshaj tawm cov kev xeem xyaum hauv peb lub vev xaib sai sai, thiab yog tias koj tso npe, koj yuav muaj peev xwm xeem tau zoo ib yam li cov uas koj yuav tau xeem CCNA xeem.
