Hnub no zaj lus qhia peb yuav mob siab rau kev teeb tsa VLAN, uas yog, peb yuav sim ua txhua yam uas peb tau tham hauv cov tshooj dhau los. Tam sim no peb yuav saib 3 nqe lus nug: tsim VLAN, muab VLAN cov chaw nres nkoj, thiab saib VLAN database.
Cia peb qhib lub qhov rais Cisco Packer tracer program nrog lub logical topology ntawm peb lub network kos los ntawm kuv.
Thawj qhov hloov SW0 txuas nrog 2 lub khoos phis tawj PC0 thiab PC1, koom ua ke hauv VLAN10 network nrog qhov chaw nyob IP ntawm 192.168.10.0/24. Raws li, IP chaw nyob ntawm cov khoos phis tawj no yuav yog 192.168.10.1 thiab 192.168.10.2. Feem ntau cov neeg txheeb xyuas tus lej VLAN los ntawm qhov thib peb octet ntawm tus IP chaw nyob, hauv peb cov ntaub ntawv nws yog 10, txawm li cas los xij qhov no tsis yog qhov yuav tsum tau tsim cov tes hauj lwm, koj tuaj yeem muab tus cim VLAN, txawm li cas los xij qhov kev txiav txim no tau txais hauv cov tuam txhab loj vim nws ua kom yooj yim rau configure lub network.
Tom ntej no yog hloov SW1, uas txuas nrog VLAN20 network nrog tus IP chaw nyob 192.168.20.0/24 nrog ob lub laptops Laptop1 thiab Laptop2.
VLAN10 nyob rau hauv pem teb 1 ntawm lub tuam txhab chaw ua haujlwm thiab sawv cev rau kev tswj xyuas kev muag khoom. Tus neeg lag luam lub Laptop0, uas yog VLAN0, txuas nrog tib lub hloov SW20. Lub network no txuas mus rau 2nd pem teb, qhov chaw uas lwm tus neeg ua haujlwm nyob, thiab nws txuas nrog rau lub chaw muag khoom, uas tej zaum yuav nyob rau hauv lwm lub tsev lossis hauv 3rd pem teb ntawm tib lub chaw ua haujlwm. Muaj 3 lub khoos phis tawj ntxiv rau ntawm no - PC2,3 thiab 4, uas yog ib feem ntawm VLAN10 network.
VLAN10, zoo li VLAN20, yuav tsum muaj kev sib txuas lus tsis muaj kev cuam tshuam rau txhua tus neeg ua haujlwm, tsis hais seb lawv nyob ntawm cov plag tsev sib txawv lossis hauv ntau lub tsev. Nov yog lub tswv yim network peb yuav saib hnub no.
Cia peb pib teeb tsa thiab pib nrog PC0. Los ntawm txhaj rau lub cim, peb yuav nkag mus rau hauv lub computer lub network teeb tsa thiab nkag mus rau IP chaw nyob 192.168.10.1 thiab subnet npog 255.255.255.0. Kuv tsis nkag mus rau qhov chaw nyob qhov rooj vim tias nws yuav tsum tau tawm ntawm ib lub zos hauv zos mus rau lwm qhov, thiab hauv peb cov ntaub ntawv peb yuav tsis cuam tshuam nrog OSI txheej 3, peb tsuas yog txaus siab rau txheej 2, thiab peb yuav tsis xav txog. routing tsheb mus rau lwm lub net.
Peb tab tom yuav teeb tsa lub intranet thiab tsuas yog cov tswv uas yog ib feem ntawm nws. Tom qab ntawd peb yuav mus rau PC2 thiab ua tib yam peb tau ua rau thawj PC. Tam sim no cia saib seb kuv puas tuaj yeem ping PC1 ntawm PC0. Raws li koj tuaj yeem pom, ping hla, thiab lub khoos phis tawj nrog tus IP chaw nyob 192.168.10.2 ntseeg siab rov qab pob ntawv. Yog li, peb tau ua tiav kev sib txuas lus ntawm PC0 thiab PC1 los ntawm kev hloov.
Txhawm rau nkag siab tias vim li cas peb ua tiav, cia peb mus rau hauv qhov hloov pauv thiab saib VLAN lub rooj.
Technically, qhov hloov pauv no muaj 5 VLANs: VLAN1 los ntawm lub neej ntawd, nrog rau 1002,1003,1004 thiab 1005. Yog tias koj saib ntawm 4 lub network kawg, koj tuaj yeem pom tias lawv tsis tau txais kev txhawb nqa thiab raug cim tias tsis txhawb nqa. Cov no yog cov network virtual ntawm qub thev naus laus zis - fddi, fddinet, trnet. Lawv tsis tau siv tam sim no, tab sis raws li kev xav tau lawv tseem suav nrog hauv cov khoom siv tshiab. Yog li, qhov tseeb, peb qhov hloov pauv tau los ntawm lub neej ntawd tsuas yog ib lub network virtual - VLAN1, yog li txhua qhov chaw nres nkoj ntawm Cisco hloov tawm ntawm lub thawv tau teeb tsa rau lub network no. Cov no yog 24 Fast Ethernet ports thiab 2 Gigabit Ethernet ports. Qhov no ua rau kev sib raug zoo ntawm cov keyboards tshiab yooj yim dua, vim tias los ntawm lub neej ntawd lawv yog txhua feem ntawm tib VLAN1.
Peb yuav tsum rov muab cov chaw nres nkoj uas tau teeb tsa los ntawm lub neej ntawd los ua haujlwm nrog VLAN1 ua haujlwm nrog VLAN10. Pob ntawv Tracer qhia tau hais tias nyob rau hauv peb cov ntaub ntawv no yog cov chaw nres nkoj Fa0 thiab Fa0/2.
Cia peb rov qab los hloov SW0 thiab teeb tsa ob lub chaw nres nkoj no. Ua li no, kuv siv lub configure davhlau ya nyob twg hais kom nkag mus rau lub ntiaj teb no configuration hom, thiab nkag mus rau cov lus txib kom configure no interface - int fastEthernet 0/1. Kuv yuav tsum tau teeb tsa qhov chaw nres nkoj no kom nkag mus rau hom kev ua haujlwm vim nws yog qhov chaw nkag nkag thiab kuv tab tom siv qhov hloov pauv hom nkag mus rau cov lus txib.
Qhov chaw nres nkoj no tau teeb tsa ua qhov chaw nres nkoj zoo li qub, tab sis yog tias kuv txuas lwm qhov hloov mus rau nws, siv DTP raws tu qauv nws yuav hloov mus rau dynamic trunk hom. Los ntawm lub neej ntawd, qhov chaw nres nkoj no belongs rau VLAN1, yog li kuv yuav tsum siv lub switchport nkag vlan 10 hais kom ua. Hauv qhov no, lub kaw lus yuav muab lus rau peb tias VLAN10 tsis muaj thiab yuav tsum tau tsim. Yog tias koj nco qab, hauv VLAN database peb tsuas muaj ib lub network - VLAN1, thiab tsis muaj VLAN10 network nyob ntawd. Tab sis peb tau thov kom hloov pauv kom nkag mus rau VLAN10, yog li peb tau txais cov lus yuam kev.
Yog li ntawd, peb yuav tsum tsim VLAN10 thiab muab qhov chaw nkag mus rau nws. Tom qab no, yog tias koj mus rau VLAN database, koj tuaj yeem pom VLAN0010 uas tau tsim tshiab, uas yog nyob rau hauv lub xeev nquag thiab uas yog tus tswv chaw nres nkoj Fa0/1.
Peb tsis tau hloov pauv rau lub khoos phis tawj, tab sis tsuas yog teeb tsa lub chaw hloov chaw uas nws txuas nrog. Tam sim no cia peb sim ping tus IP chaw nyob 192.168.10.2, uas peb tau ua tiav ob peb feeb dhau los. Peb ua tsis tiav vim qhov chaw nres nkoj PC0 txuas nrog tam sim no ntawm VLAN10, thiab qhov chaw nres nkoj PC1 txuas nrog tseem nyob ntawm VLAN1, thiab tsis muaj kev sib txuas ntawm ob lub network. Txhawm rau tsim kev sib txuas lus ntawm cov khoos phis tawj no, koj yuav tsum teeb tsa ob lub chaw nres nkoj ua haujlwm nrog VLAN10. Kuv nkag mus rau lub ntiaj teb configuration hom dua thiab ua tib yam rau switchport f0/2.
Wb rov saib dua ntawm lub rooj VLAN. Tam sim no peb pom tias VLAN10 tau teeb tsa ntawm cov chaw nres nkoj Fa0/1 thiab Fa0/2. Raws li peb tuaj yeem pom, tam sim no ping tau ua tiav, vim tias ob qhov chaw nres nkoj ntawm SW0 hloov mus rau cov khoom siv txuas nrog rau tib lub network. Cia peb sim hloov lub npe ntawm lub network los qhia nws lub hom phiaj. Yog tias peb xav hloov pauv rau VLAN, peb yuav tsum mus rau hauv kev teeb tsa ntawm lub network no.
Ua li no, kuv ntaus vlan 10 thiab koj tuaj yeem pom tias cov lus txib tau hloov pauv los ntawm Hloov (config) # mus rau Hloov (config-vlan) #. Yog tias peb sau cov lus nug, lub kaw lus yuav qhia peb tsuas yog 3 cov lus txib: tawm, npe thiab tsis yog. Kuv tuaj yeem muab lub npe rau lub network siv lub npe hais kom ua, xa cov lus txib rov qab rau lawv lub xeev qub los ntawm kev ntaus ntawv tsis yog, lossis txuag kuv cov kev hloov pauv siv cov lus txib tawm. Yog li kuv nkag mus rau cov lus txib npe SALES thiab tawm.
Yog tias koj saib ntawm VLAN database, koj tuaj yeem paub tseeb tias peb cov lus txib tau raug ua tiav thiab cov qub VLAN10 tam sim no hu ua SALES - sales department. Yog li, peb txuas 2 lub khoos phis tawj hauv peb lub chaw ua haujlwm rau lub network tsim ntawm chav muag khoom. Tam sim no peb yuav tsum tau tsim ib lub network rau lub tuam txhab lag luam. Txhawm rau txuas lub Laptop0 lub laptop rau lub network no, koj yuav tsum nkag mus rau nws lub network teeb tsa thiab nkag mus rau IP chaw nyob 192.168.20.1 thiab subnet npog 255.255.255.0; peb tsis xav tau lub rooj vag qub. Tom qab ntawd koj yuav tsum rov qab mus rau qhov hloov chaw, nkag mus rau qhov chaw nres nkoj nrog cov lus txib int fa0/3 thiab nkag mus rau cov lus txib hloov chaw nkag. Cov lus txib tom ntej yuav yog switchport nkag vlan 20.
Peb rov tau txais cov lus hais tias xws li VLAN tsis muaj thiab yuav tsum tau tsim. Koj tuaj yeem mus rau lwm txoj kev - Kuv yuav tawm ntawm Hloov chaw teeb tsa (config-yog), mus rau Hloov (config) thiab nkag mus rau vlan 20 hais kom ua, yog li tsim VLAN20 network. Ntawd yog, koj tuaj yeem ua ntej tsim VLAN20 network, muab nws lub npe MARKETING, txuag cov kev hloov pauv nrog cov lus txib tawm, thiab tom qab ntawd teeb tsa qhov chaw nres nkoj rau nws.
Yog tias koj nkag mus rau hauv VLAN database nrog sh vlan hais kom ua, koj tuaj yeem pom MARKETING network peb tsim thiab qhov chaw sib txuas Fa0/3. Kuv yuav tsis muaj peev xwm ping computers los ntawm lub laptop no rau ob qho laj thawj: peb muaj VLANs sib txawv thiab peb cov khoom siv sib txawv subnets. Txij li thaum lawv koom nrog VLANs sib txawv, qhov hloov pauv yuav tso lub laptop cov pob ntawv xa mus rau lwm lub network vim nws tsis muaj qhov chaw nres nkoj uas yog VLAN20.
Raws li kuv tau hais, lub tuam txhab tab tom nthuav dav, lub chaw ua haujlwm me me hauv pem teb tsis txaus, yog li nws tso lub tuam txhab lag luam rau hauv 2nd pem teb ntawm lub tsev, nruab cov khoos phis tawj rau 2 tus neeg ua haujlwm thiab xav muab kev sib txuas lus nrog lub tuam txhab lag luam ntawm thawj pem teb. Txhawm rau ua qhov no, koj yuav tsum xub tsim lub cev ntawm ob lub keyboards - chaw nres nkoj Fa0/4 ntawm thawj qhov hloov pauv thiab chaw nres nkoj Fa0/1 ntawm qhov hloov thib ob. Txhawm rau ua qhov no, kuv mus rau hauv SW0 nqis thiab nkag mus rau cov lus txib int f0/4 thiab hloov pauv hom pob tw.
Muaj ib qho kev hloov pauv lub cev enc encapsulation hais kom ua, tab sis nws tsis yog siv rau hauv cov keyboards tshiab vim tias lawv siv 802.1q encapsulation technology. Txawm li cas los xij, cov qauv qub ntawm Cisco keyboards siv cov txheej txheem ISL uas yog tus tswv, uas tsis siv lawm, txij li tag nrho cov keyboards tam sim no nkag siab txog .1Q raws tu qauv. Txoj kev no koj tsis tas yuav siv qhov hloov pauv lub cev enc hais kom ua.
Yog tias koj tam sim no mus rau VLAN database, koj tuaj yeem pom qhov chaw nres nkoj Fa0/4 tau ploj ntawm nws. Qhov no yog vim lub rooj no tsuas yog teev cov chaw nkag nkag uas muaj nyob rau ntawm VLAN tshwj xeeb. Txhawm rau kom pom lub pob tw ntawm qhov hloov pauv, koj yuav tsum siv sh int trunk hais kom ua.
Nyob rau hauv lub qhov rais kab hais kom ua, peb pom tias chaw nres nkoj Fa0/4 yog enabled, encapsulates tshaj 802.1q raws tu qauv, thiab belongs rau haiv neeg vlan 1. Raws li peb paub, yog hais tias qhov chaw nres nkoj lub cev no tau txais untagged tsheb, nws cia li xa nws mus rau haiv neeg vlan. 1 network. Nyob rau hauv zaj lus qhia tom ntej peb yuav tham txog kev teeb tsa ib txwm vlan, rau tam sim no cia li nco ntsoov tias lub pob tw qhov chaw zoo li cas rau ib qho khoom siv.
Tam sim no kuv mus rau qhov thib ob hloov SW1, nkag mus rau int f0/1 chaw teeb tsa hom thiab rov ua qhov chaw nres nkoj teeb tsa ib ntus zoo ib yam li rooj plaub dhau los. Ob lub chaw nres nkoj Fa0/2 thiab Fa0/3, uas lub laptops ntawm lub tuam txhab lag luam cov neeg ua haujlwm txuas nrog, yuav tsum tau teeb tsa hauv hom kev nkag thiab xa mus rau VLAN20 network.
Hauv cov ntaub ntawv dhau los, peb tau teeb tsa txhua qhov chaw nres nkoj ntawm qhov hloov pauv ib tus zuj zus, thiab tam sim no kuv xav qhia koj yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Koj tuaj yeem nkag mus rau cov lus txib kom teeb tsa qhov ntau ntawm cov interfaces int range f0/2-3, uas yuav ua rau cov kab hais kom ua kom dhau los ua Hloov (config-if-range)#, thiab koj tuaj yeem nkag mus rau tib qhov kev txwv lossis siv tib cov lus txib. txhawm rau teev ntau yam ntawm cov chaw nres nkoj, piv txwv li, ib txhij rau 20 chaw nres nkoj.
Hauv qhov piv txwv yav dhau los, peb siv tib hom kev nkag mus rau switchport thiab switchport access vlan 10 commands ob peb zaug rau ob peb lub chaw hloov chaw. Cov lus txib no tuaj yeem nkag mus ib zaug yog tias koj siv ntau qhov chaw nres nkoj. Tam sim no kuv yuav nkag mus rau switchport hom nkag thiab switchport nkag vlan 20 cov lus txib rau qhov chaw nres nkoj xaiv.
Txij li thaum VLAN20 tseem tsis tau muaj, lub kaw lus yuav tsim nws txiav. Kuv ntaus tawm kom txuag kuv cov kev hloov pauv thiab nug kom pom VLAN lub rooj. Raws li koj tuaj yeem pom, cov chaw nres nkoj Fa0/2 thiab Fa0/3 tam sim no yog ib feem ntawm VLAN20 tsim tshiab.
Tam sim no kuv yuav teeb tsa tus IP chaw nyob ntawm lub laptops nyob rau hauv pem teb thib ob ntawm peb qhov chaw ua haujlwm: Laptop1 yuav tau txais qhov chaw nyob ntawm 192.168.20.2 thiab subnet npog ntawm 255.255.255.0, thiab Laptop2 yuav tau txais IP chaw nyob ntawm 192.168.20.3. Cia peb kuaj xyuas lub network ua haujlwm los ntawm pinging thawj lub laptop ntawm qhov thib ob. Raws li koj tuaj yeem pom, ping tau ua tiav vim tias ob lub cuab yeej yog ib feem ntawm tib VLAN thiab txuas nrog tib lub hloov pauv.
Txawm li cas los xij, lub tuam txhab lag luam laptops ntawm thawj thiab thib ob pem teb txuas nrog cov hloov pauv sib txawv, txawm tias lawv nyob ntawm tib VLAN. Cia peb xyuas seb kev sib txuas lus ntawm lawv tau ua li cas, ua li no, kuv yuav ping lub laptop ntawm thawj pem teb nrog IP chaw nyob 2 los ntawm Laptop192.168.20.1. Raws li koj tuaj yeem pom, txhua yam ua haujlwm tsis muaj teeb meem txawm hais tias lub laptops txuas nrog cov keyboards sib txawv. Kev sib txuas lus yog nqa tawm vim qhov tseeb tias ob lub keyboards txuas nrog lub cev.
Kuv puas tuaj yeem tsim kev sib txuas ntawm Laptop2 thiab PC0? Tsis yog, kuv ua tsis tau, vim lawv koom nrog VLANs sib txawv. Tam sim no peb yuav teeb tsa lub network ntawm cov khoos phis tawj PC2,3,4, uas peb yuav xub tsim lub pob tw ntawm qhov hloov thib ob Fa0/4 thiab qhov thib peb hloov Fa0/1.
Kuv mus rau hauv SW1 nqis thiab ntaus config t hais kom ua, tom qab uas kuv hu rau int f0/4, ces nkag mus rau lub switchport hom pob tw thiab tawm commands. Kuv configure peb hloov SW2 tib yam. Peb tsim ib lub pob tw, thiab koj tuaj yeem pom tias tom qab qhov kev teeb tsa tau siv, cov xim ntawm cov chaw nres nkoj tau hloov ntawm txiv kab ntxwv mus rau ntsuab. Tam sim no koj yuav tsum teeb tsa cov chaw nres nkoj Fa0 / 2,0 / 3,0 / 4, uas lub chaw muag khoom cov khoos phis tawj koom nrog VLAN10 network txuas nrog. Txhawm rau ua qhov no, kuv nkag mus rau hauv qhov chaw ntawm SW2 hloov, xaiv qhov ntau ntawm cov chaw nres nkoj f0/2-4 thiab siv qhov hloov chaw nkag mus thiab hloov chaw nkag nkag vlan 10 cov lus txib rau lawv. Vim tias tsis muaj VLAN10 network ntawm cov chaw nres nkoj no, nws yog tsim los ntawm qhov system. Yog tias koj saib ntawm VLAN database ntawm qhov hloov pauv no, koj tuaj yeem pom tias tam sim no ports Fa0/2,0/3,0/4 belongs rau VLAN10.
Tom qab ntawd, koj yuav tsum teeb tsa lub network rau txhua tus ntawm 3 lub khoos phis tawj no los ntawm kev nkag mus rau IP chaw nyob thiab lub qhov ncauj qhov ntswg subnet. PC2 tau txais qhov chaw nyob 192.168.10.3, PC3 tau txais qhov chaw nyob 192.168.10.4, thiab PC4 tau txais IP chaw nyob 192.168.10.5.
Txhawm rau teb cov lus nug ntawm seb peb lub network puas ua haujlwm, cia peb ping PC0 ntawm thawj pem teb los ntawm PC4, nyob rau hauv pem teb 3 lossis hauv lwm lub tsev. Pinging ua tsis tiav, yog li cia peb sim xyuas seb vim li cas peb ua tsis tau.
Thaum peb sim ping Laptop0 los ntawm Laptop2, txhua yam ua haujlwm zoo, txawm hais tias lub laptops tau txuas nrog cov keyboards sib txawv. Vim li cas nws thiaj li tam sim no, thaum peb lub tuam txhab muag khoom siv computer tau txuas nrog cov keyboards sib txawv txuas nrog lub cev, lub ping tsis ua haujlwm? Yuav kom nkag siab qhov ua rau ntawm qhov teeb meem, koj yuav tsum nco ntsoov tias qhov hloov pauv ua haujlwm li cas.
Thaum peb xa ib pob ntawv los ntawm PC4 los hloov SW2, nws pom tias pob ntawv tuaj txog ntawm chaw nres nkoj Fa0/4. Qhov hloov mus kuaj nws cov ntaub ntawv thiab pom tias chaw nres nkoj Fa0/4 belongs rau VLAN10. Tom qab qhov no, qhov hloov pauv cim npe nrog tus lej xov tooj, uas yog, txuas VLAN10 header mus rau pob ntawv tsheb, thiab xa nws raws lub pob tw mus rau qhov thib ob hloov SW1. Qhov kev hloov no "nyeem" lub header thiab pom tias pob ntawv yog destined rau VLAN10, saib rau hauv nws VLAN database thiab, pom tias tsis muaj VLAN10 nyob ntawd, muab cov pob ntawv pov tseg. Yog li, cov khoom siv PC2,3 thiab 4 tuaj yeem sib txuas lus nrog ib leeg yam tsis muaj teeb meem, tab sis kev sim tsim kev sib txuas lus nrog cov khoos phis tawj PC0 thiab PC1 ua tsis tiav vim hloov SW1 tsis paub dab tsi txog VLAN10 network.
Peb tuaj yeem kho qhov teeb meem no yooj yim los ntawm kev mus rau SW1 nqis, tsim VLAN10 siv vlan 10 hais kom ua thiab nkag mus rau nws lub npe MARKETING. Cia peb sim rov ua qhov ping - koj pom tias thawj peb pob ntawv raug muab pov tseg, thiab thib plaub tau ua tiav. Qhov no tau piav qhia los ntawm qhov tseeb tias qhov hloov pauv thawj zaug tau kuaj xyuas IP chaw nyob thiab txiav txim siab MAC chaw nyob, qhov no tau siv qee lub sijhawm, yog li thawj peb pob ntawv raug muab pov tseg los ntawm lub sijhawm. Tam sim no qhov kev sib txuas tau tsim vim qhov hloov pauv tau hloov kho nws qhov chaw nyob MAC thiab xa cov pob ntawv ncaj qha mus rau qhov chaw nyob xav tau.
Txhua yam kuv tau ua los txhim kho qhov teeb meem yog mus rau hauv qhov chaw ntawm qhov hloov pauv nruab nrab thiab tsim VLAN10 network nyob ntawd. Yog li, txawm tias lub network tsis ncaj qha cuam tshuam nrog kev hloov pauv, nws tseem yuav tsum paub txog txhua qhov kev koom tes hauv kev sib txuas hauv network. Txawm li cas los xij, yog tias koj lub network muaj ntau pua lub keyboards, koj yuav tsis tuaj yeem nkag mus rau hauv qhov chaw ntawm txhua tus thiab manually configure VLAN IDs. Tias yog vim li cas peb siv VTP raws tu qauv, qhov kev teeb tsa uas peb yuav saib hauv video nyeem tom ntej.
Yog li, hnub no peb tau hais txog txhua yam peb tau npaj tseg: yuav ua li cas los tsim VLANs, yuav ua li cas muab VLAN ports, thiab saib VLAN database li cas. Txhawm rau tsim cov tes hauj lwm, peb nkag mus rau lub ntiaj teb hloov kev teeb tsa hom thiab siv vlan <number> hais kom ua, peb tuaj yeem muab lub npe rau lub network tsim siv lub npe <name> hais kom ua.
Peb tseem tuaj yeem tsim VLAN lwm txoj hauv kev los ntawm kev nkag mus rau hom interface thiab siv qhov hloov pauv nkag vlan <number> hais kom ua. Yog tias tsis muaj lub network nrog tus lej no, nws yuav raug tsim los ntawm qhov system. Nco ntsoov siv cov lus txib tawm tom qab hloov pauv rau qhov chaw pib, txwv tsis pub lawv yuav tsis raug cawm hauv VLAN database. Tom qab ntawd koj tuaj yeem xa cov chaw nres nkoj rau cov VLAN tshwj xeeb siv cov lus txib tsim nyog.
Lub switchport hom nkag mus hais kom hloov lub interface rau static nkag-chaw nres nkoj hom, tom qab uas tus naj npawb ntawm cov coj VLAN raug xa mus rau qhov chaw nres nkoj nrog switchport nkag vlan <number> hais kom ua. Txhawm rau saib VLAN database, siv cov lus qhia vlan, uas yuav tsum tau nkag mus rau hauv cov neeg siv EXEC hom. Txhawm rau saib cov npe ntawm cov chaw nres nkoj lub cev, siv cov lus qhia int trunk.
Ua tsaug uas koj nyob nrog peb. Koj puas nyiam peb cov ntawv? Xav pom cov ntsiab lus nthuav ntxiv? Txhawb nqa peb los ntawm kev tso ib qho kev txiav txim lossis qhia rau cov phooj ywg, 30% luv nqi rau cov neeg siv Habr ntawm qhov tshwj xeeb analogue ntawm nkag-theem servers, uas tau tsim los ntawm peb rau koj: (muaj nrog RAID1 thiab RAID10, mus txog 24 cores thiab mus txog 40GB DDR4).
