Isifundo sanamhlanje siza kuzinikela kwiisetingi zeVLAN, oko kukuthi, siya kuzama ukwenza yonke into ebesithetha ngayo kwizifundo ezidlulileyo. Ngoku siza kujonga imibuzo emi-3: ukwenza iVLAN, ukwabela izibuko zeVLAN, nokujonga i-database yeVLAN.
Masivule ifestile yenkqubo yokulandelela iCisco Packer ngetopology enengqondo yothungelwano lwethu ezotywe ndim.
Ukutshintsha kokuqala kwe-SW0 kuqhagamshelwe kwiikhompyuter ezi-2 ze-PC0 kunye ne-PC1, ezidityaniswe kwinethiwekhi ye-VLAN10 enoluhlu lwedilesi ye-IP ye-192.168.10.0/24. Ngokufanelekileyo, iidilesi ze-IP zezi khompyutha ziya kuba ngu-192.168.10.1 kunye no-192.168.10.2. Ngokuqhelekileyo abantu bachonga inombolo ye-VLAN nge-octet yesithathu yedilesi ye-IP, kwimeko yethu yi-10, nangona kunjalo oku akusiyo imeko enyanzelekileyo yokutyumba amanethiwekhi, unokwabela nayiphi na isazisi seVLAN, nangona kunjalo lo myalelo wamkelwa kwiinkampani ezinkulu kuba yenza kubelula ukuqwalasela inethiwekhi.
Okulandelayo kukutshintsha i-SW1, eqhagamshelwe kuthungelwano lweVLAN20 ngedilesi ye-IP 192.168.20.0/24 ngeelaptops ezimbini zeLaptop1 kunye neLaptop2.
I-VLAN10 ifumaneka kumgangatho we-1 weofisi yenkampani kwaye imele inethiwekhi yolawulo lokuthengisa. ILaptop0 yomthengisi, eyeVLAN0, iqhagamshelwe kwiswitshi efanayo SW20. Le nethiwekhi ifikelela kumgangatho we-2, apho abanye abasebenzi bakhona, kwaye ixhunyiwe kwisebe lokuthengisa, elinokuthi libekwe kwesinye isakhiwo okanye kumgangatho we-3 kwiofisi enye. Kukho ezinye iikhompyuter ezi-3 ezifakwe apha - i-PC2,3 kunye ne-4, eziyinxalenye yenethiwekhi ye-VLAN10.
I-VLAN10, njenge-VLAN20, kufuneka ibonelele ngonxibelelwano olungaphazamisekiyo kubo bonke abasebenzi, nokuba babekwe kwimigangatho eyahlukeneyo okanye kwizakhiwo ezahlukeneyo. Lo ngumbono womnatha esiza kuwujonga namhlanje.
Masiqalise ukuseta kwaye siqale ngePC0. Ngokunqakraza kwi icon, siya kungena useto lwenethiwekhi yekhompyuter kwaye singenise idilesi ye-IP 192.168.10.1 kunye ne-subnet mask 255.255.255.0. Andiyifaki idilesi yesango engagqibekanga kuba iyadingeka ukuphuma kwinethiwekhi yendawo ukuya kwenye, kwaye kwimeko yethu asiyi kujongana ne-OSI layer 3, sinomdla kuphela kwi-2, kwaye asiyi kuqwalasela. ukuhambisa itrafikhi ukuya komnye umnatha.
Siza kuqwalasela i-intranethi kwaye kuphela abo bamkeli abayinxalenye yayo. Emva koko siya kwiPC2 kwaye senze into enye esiyenze kwiPC yokuqala. Ngoku makhe sibone ukuba ndiyakwazi uku-ping PC1 ukusuka kwi-PC0. Njengoko ubona, i-ping idlula, kunye nekhompyutheni enedilesi ye-IP 192.168.10.2 ngokuzithemba ibuyisela iipakethi. Ke, siseke ngempumelelo unxibelelwano phakathi kwePC0 kunye nePC1 ngokutshintsha.
Ukuqonda ukuba kutheni siphumelele, masingene kwisethingi yokutshintsha kwaye sijonge itafile yeVLAN.
Ngokobuchwephesha, olu tshintsho lune-5 VLANs: VLAN1 ngokungagqibekanga, kunye ne-1002,1003,1004 kunye ne-1005. Ukuba ujonga kwinethiwekhi ezi-4 zokugqibela, ungabona ukuba azixhaswanga kwaye ziphawulwe ukuba azixhaswanga. Olu luthungelwano lwenyani lobuchwephesha obudala - fddi, fddinet, trnet. Azisetyenziswa okwangoku, kodwa ngokweemfuno zobugcisa zisaqukwa kwizixhobo ezitsha. Ngaloo ndlela, eneneni, iswitshi yethu iye ngokungagqibekanga inethwekhi enye kuphela virtual - VLAN1, ngoko onke amazibuko naluphi na utshintsho Cisco ngaphandle kwebhokisi ziqwalaselwe le network. Ezi zichwephesha ze-24 Fast Ethernet kunye ne-2 Gigabit Ethernet port. Oku kwenza ukuhambelana kokutshintsha okutsha kube lula kakhulu, kuba ngokungagqibekanga zonke ziyinxalenye yeVLAN1 efanayo.
Kufuneka siwanike ngokutsha amazibuko abumbeke ngokungagqibekanga ukuze asebenze neVLAN1 ukuze asebenze neVLAN10. I-Packet Tracer ibonisa ukuba kwimeko yethu ezi zichwephesha ze-Fa0 kunye ne-Fa0 / 2.
Masibuyele ekutshintsheni i-SW0 kwaye siqwalasele la mazibuko mabini. Ukwenza oku, ndisebenzisa umyalelo woqwalaselo lwe-terminal ukufaka imo yoqwalaselo lwehlabathi, kwaye ngenisa umyalelo wokuqwalasela olu jongano- int fastEthernet 0/1. Ndifuna ukuseta elizibuko ukufikelela kwindlela yokusebenza kuba lizibuko lofikelelo kwaye ndisebenzisa umyalelo wofikelelo lwendlela yokutshintsha.
Eli zibuko liqwalaselwe njengezibuko lonikezelo olungatshintshiyo, kodwa ukuba ndidibanisa enye iswitsha kuyo, usebenzisa iDTP protocol izakutshintshela kwindlela yesiqu esiguqukayo. Ngokungagqibekanga, elizibuko lelika VLAN1, ngoko ke kufuneka ndisebenzise i-switchport ufikelelo vlan 10. Kulo mzekelo, inkqubo iya kusinika umyalezo wokuba iVLAN10 ayikho kwaye kufuneka yenziwe. Ukuba uyakhumbula, kwi-database ye-VLAN sinenethiwekhi enye kuphela - i-VLAN1, kwaye akukho intanethi ye-VLAN10 apho. Kodwa sicele iswitshi ukunika ukufikelela kwi-VLAN10, ke sifumene umyalezo wempazamo.
Ke ngoko, kufuneka senze iVLAN10 kwaye sinikeze eli zibuko lokufikelela kuyo. Emva koku, ukuba uya kwi-database ye-VLAN, ungabona i-VLAN0010 esanda kwenziwa, ekwimo esebenzayo kwaye ephethe i-port Fa0/1.
Asizange senze naluphi na utshintsho kwikhompyuter, kodwa siqwalasele ngokulula izibuko eliqhagamshelwe kulo. Ngoku makhe sizame ukubethelela idilesi yeIP 192.168.10.2, esiyenze ngempumelelo kwimizuzu embalwa edlulileyo. Asiphumelelanga kuba i-port0 ye-PC10 iqhagamshelwe kuyo ngoku ikwiVLAN1, kwaye izibuko i-PC1 eqhagamshelwe kuyo isekwi-VLAN10, kwaye akukho nxibelelwano phakathi kweenethiwekhi ezimbini. Ukuze kusekwe unxibelelwano phakathi kwezi khompyutha, kufuneka uqwalasele omabini amazibuko ukusebenza nge VLAN0. Ndifaka imowudi yoqwalaselo lwehlabathi kwakhona kwaye ndenze okufanayo kwi-switchport f2/XNUMX.
Masijonge kwakhona kwitafile yeVLAN. Ngoku siyabona ukuba iVLAN10 iqwalaselwe kumazibuko eFa0/1 kunye neFa0/2. Njengoko sibona, ngoku i-ping iphumelele, kuba omabini amazibuko e-SW0 switsha apho izixhobo ziqhagamshelwe kuthungelwano olufanayo. Masizame ukutshintsha igama lenethiwekhi ukubonisa injongo yayo. Ukuba sifuna ukwenza naluphi na utshintsho kwiVLAN, kufuneka singene kuqwalaselo lwale network.
Ukwenza oku, ndichwetheza i-vlan 10 kwaye uyabona ukuba umyalelo womyalelo utshintshile ukusuka kwiTshintsho (config) # ukuya kwiTshintsho (config-vlan) #. Ukuba sifaka uphawu lombuzo, inkqubo iya kusibonisa kuphela imiyalelo emi-3 enokwenzeka: ukuphuma, igama kunye no. Ndinokwabela igama kuthungelwano usebenzisa umyalelo wegama, ukubuyisela imiyalelo kwimeko yabo engagqibekanga ngokuchwetheza uhayi, okanye ugcine utshintsho lwam usebenzisa umyalelo wokuphuma. Ngoko ke ndifaka imiyalelo igama UKUTHENGISA kwaye uphume.
Ukuba ujonga i-database ye-VLAN, unokuqinisekisa ukuba imiyalelo yethu yenziwe kwaye i-VLAN10 yangaphambili ibizwa ngokuba yi-SALES - isebe lokuthengisa. Ke, siqhagamshele iikhompyuter ezi-2 kwiofisi yethu kwinethiwekhi eyenziwe yecandelo lokuthengisa. Ngoku kufuneka senze inethiwekhi yesebe lezentengiso. Ukuze uqhagamshele iLaptop0 kule nethiwekhi, kufuneka ufake izicwangciso zayo zenethiwekhi kwaye ufake idilesi ye-IP 192.168.20.1 kunye ne-subnet mask 255.255.255.0; asiyifuni isango elingagqibekanga. Emva koko kufuneka ubuyele kwisethingi yokutshintsha, faka izicwangciso ze-port kunye nomyalelo we-int fa0/3 kwaye ufake umyalelo wokufikelela kwimodi yokutshintsha. Umyalelo olandelayo uya kuba yi-switchport ukufikelela kwi-vlan 20.
Siphinda sifumana umyalezo wokuba iVLAN enjalo ayikho kwaye kufuneka yenziwe. Ungahamba ngenye indlela - ndiza kuphuma kwi-Switch port configuration (config-ukuba), yiya kwiTshintsho (config) kwaye ufake i-vlan 20 umyalelo, ngokwenza oko udala inethiwekhi yeVLAN20. Oko kukuthi, ungadala inethiwekhi yeVLAN20 kuqala, uyinike igama UKUTHENGISA, gcina utshintsho ngomyalelo wokuphuma, kwaye emva koko uqwalasele izibuko kuyo.
Ukuba ungena kwi-database ye-VLAN ngomyalelo we-sh vlan, ungabona inethiwekhi YOKUTHENGISA esiyenzileyo kunye ne-port ehambelanayo Fa0/3. Andiyi kukwazi ukucofa iikhompyuter kule laptop ngenxa yezizathu ezibini: sineeVLAN ezahlukeneyo kunye nezixhobo zethu zeze-subnets ezahlukeneyo. Kuba bangabakwaVLANs ezahlukeneyo, iswitshi iya kuwisa iipakethe zelaptop eziqondiswe kwenye inethiwekhi kuba ayinayo izibuko eyeyakwaVLAN20.
Njengoko benditshilo, inkampani iyanda, iofisi encinci kumgangatho ophantsi ayanelanga, ngoko ibeka isebe lokuthengisa kumgangatho we-2 wesakhiwo, ifake iikhompyuter apho kubasebenzi be-2 kwaye ifuna ukubonelela ngonxibelelwano kunye nesebe lokuthengisa. umgangatho wokuqala. Ukwenza oku, kufuneka uqale wenze isiqu phakathi kweeswitshi ezimbini - izibuko Fa0/4 lokutshintsha kokuqala kunye nezibuko Fa0/1 sokutshintsha kwesibini. Ukwenza oku, ndingena kwisethingi ye-SW0 kwaye ndingenise imiyalelo int f0/4 kunye ne-switchport mode trunk.
Kukho i-switchport trunk enc encapsulation command, kodwa ayisetyenziswanga ekutshintsheni okutsha kuba ngokungagqibekanga basebenzisa iteknoloji ye-802.1q encapsulation. Nangona kunjalo, iimodeli ezindala zokutshintsha kweCisco zisebenzise iprotocol ye-ISL yobunikazi, engasasetyenziswa, kuba zonke iitshintshi ngoku ziqonda iprotocol ye-.1Q. Ngale ndlela akusekho mfuneko yokuba usebenzise i-switchport trunk enc umyalelo.
Ukuba ngoku uye kwi-database ye-VLAN, ungabona ukuba i-port Fa0/4 ilahlekile kuyo. Oku kungenxa yokuba le theyibhile idwelisa kuphela izibuko zofikelelo ezizezeVLAN ethile. Ukuze ubone izibuko zesiqu sotshintsho, kufuneka usebenzise umyalelo we-sh int trunk.
Kwifestile yelayini yomyalelo, sibona ukuba izibuko iFa0/4 yenziwe, igqume ngaphezulu kwe 802.1q protocol, kwaye yeyemveli vlan 1. Njengoko sisazi, ukuba esi zibuko somboko sifumana itrafikhi engabhalwanga, iyigqithisela phambili ngokuzenzekelayo kwivlan yakudala. Inethiwekhi 1. Kwisifundo esilandelayo siza kuthetha ngokuseta i-vlan yendabuko, okwangoku khumbula nje ukuba izicwangciso ze-trunk zibukeka njani kwisixhobo esinikiweyo.
Ngoku ndiya kwiswitshi yesibini SW1, ngenisa int f0/1 useto lwemowudi kwaye uphinde ulandelelwano lokuseta izibuko olufana nolo lwangaphambili. Izibuko ezimbini ze-Fa0/2 kunye ne-Fa0/3, apho ii-laptops zabasebenzi besebe lokuthengisa zixhunyiwe, kufuneka ziqwalaselwe kwimodi yokufikelela kwaye zinikezelwe kwinethiwekhi yeVLAN20.
Kwimeko yangaphambili, siqwalasele izibuko ngalinye lokutshintsha ngokwahlukeneyo, kwaye ngoku ndifuna ukukubonisa indlela yokukhawulezisa le nkqubo usebenzisa ithemplate yomgca womyalelo. Ungangenisa umyalelo wokuqwalasela uluhlu lojongano lwe int kuluhlu f0/2-3, nto leyo eya kubangela ulayini womyalelo wokwazisa ukuba ube yiTshintsho (config-ukuba-uluhlu) #, kwaye ungangenisa iparameter efanayo okanye usebenzise umyalelo ofanayo. kuluhlu oluchaziweyo lwamazibuko, umzekelo, ngaxeshanye kumazibuko angama-20.
Kumzekelo wangaphambili, sisebenzise ukufikelela kwimowudi yokutshintsha okufanayo kunye nokufikelela kwi-switchport ye-vlan 10 imiyalelo kaninzi kwiizibuko ezininzi zokutshintsha. Le miyalelo ingangeniswa kube kanye ukuba usebenzisa uluhlu lwamazibuko. Ngoku ndiza kungena kwimowudi yokutshintsha kunye nokufikelela kwi-switchport ye-vlan 20 imiyalelo yoluhlu olukhethiweyo lwezibuko.
Ekubeni i-VLAN20 ingekho okwangoku, inkqubo iya kuyenza ngokuzenzekelayo. Ndichwetheza ukuphuma ukugcina utshintsho lwam kwaye ndicele ukubona itafile yeVLAN. Njengoko ubona, amazibuko Fa0/2 kunye Fa0/3 ngoku yinxalenye esanda kwenziwa VLAN20.
Ngoku ndiza kumisa iidilesi ze-IP zeelaptops kumgangatho wesibini weofisi yethu: ILaptop1 iya kufumana idilesi ye-192.168.20.2 kunye ne-subnet mask ye-255.255.255.0, kunye neLaptop2 iya kufumana idilesi ye-IP ye-192.168.20.3. Makhe sijonge ukusebenza kwenethiwekhi ngokubethelela ilaptop yokuqala ukusuka kweyesibini. Njengoko ubona, i-ping iphumelele kuba zombini izixhobo ziyinxalenye yeVLAN efanayo kwaye ziqhagamshelwe kwisitshixo esifanayo.
Nangona kunjalo, iilaptops zesebe lokuthengisa kumgangatho wokuqala kunye nowesibini ziqhagamshelwe kwiiswitshi ezahlukeneyo, nangona zikwiVLAN enye. Makhe sijonge ukuba unxibelelwano phakathi kwabo luqinisekiswa njani.Ukwenza oku, ndiya kubethelela ilaptop kumgangatho wokuqala kunye nedilesi ye-IP 2 ukusuka kwiLaptop192.168.20.1. Njengoko ubona, yonke into isebenza ngaphandle kweengxaki nangona i-laptops ixhunyiwe kwiiswitshi ezahlukeneyo. Unxibelelwano lwenziwa ngenxa yokuba zombini iitshintshi zixhunyiwe nge-trunk.
Ngaba ndingaseka umdibaniso phakathi kweLaptop2 kunye nePC0? Hayi, andikwazi, kuba zezohlukeneyo VLANs. Ngoku siza kuqwalasela uthungelwano lweekhompyuter zePC2,3,4, apho siya kuqala ukudala i-trunk phakathi kokutshintsha kwesibini kweFa0/4 kunye neyesithathu iswitshi iFa0/1.
Ndingena kwisethingi ye-SW1 kwaye ndichwetheze i-config t yomyalelo, emva koko ndifowunela int f0/4, emva koko ndingenise imowudi yokutshintsha kwesiqu kunye nemiyalelo yokuphuma. Ndiqwalasela iswitshi yesithathu SW2 ngendlela efanayo. Senze i-trunk, kwaye unokubona ukuba emva kokuba useto lusebenze, umbala wamazibuko watshintsha ukusuka kwi-orenji ukuya eluhlaza. Ngoku kufuneka uqwalasele amazibuko Fa0/2,0/3,0/4, apho iikhomputha zecandelo lokuthengisa ezizezothungelwano lweVLAN10 ziqhagamshelwe. Ukwenza oku, ndingena kwizicwangciso zokutshintsha kwe-SW2, khetha uluhlu lwamazibuko f0/2-4 kwaye ndisebenzise imowudi yokutshintshela yokufikelela kunye nokufikelela kwi-switchport ye-vlan 10 imiyalelo kubo.Kuba akukho nethiwekhi ye-VLAN10 kula mazibuko. yenziwe ngokuzenzekelayo yinkqubo. Ukuba ujonga kuluhlu lwedatha yeVLAN yolu switsha, ungabona ukuba ngoku amazibuko Fa0/2,0/3,0/4 akwiVLAN10.
Emva koku, kufuneka uqwalasele inethiwekhi nganye kwezi 3 iikhomputha ngokungenisa iidilesi ze-IP kunye ne-subnet masks. I-PC2 ifumana idilesi 192.168.10.3, i-PC3 ifumana idilesi 192.168.10.4, kwaye i-PC4 ifumana idilesi ye-IP 192.168.10.5.
Ukuphendula umbuzo wokuba inethiwekhi yethu iyasebenza, masibethe i-PC0 kumgangatho wokuqala ukusuka kwi-PC4, ebekwe kumgangatho we-3 okanye kwesinye isakhiwo. I-Pinging ayiphumelelanga, ngoko ke makhe sizame ukufumanisa ukuba kutheni singenakuyenza.
Xa sizama ukucofa iLaptop0 kwiLaptop2, yonke into yasebenza kakuhle, nangona iilaptops ziqhagamshelwe kwizitshixo ezahlukeneyo. Kutheni le nto ngoku, xa iikhomputha zethu zecandelo lentengiso ziqhagamshelwe ngokuchanekileyo kwizitshixo ezahlukeneyo eziqhagamshelwe yi-trunk, i-ping ayisebenzi? Ukuze uqonde isizathu sengxaki, kufuneka ukhumbule indlela umtshintshi osebenza ngayo.
Xa sithumela ipakethi ukusuka kwi-PC4 ukutshintshela i-SW2, ibona ukuba ipakethi ifika kwi-port Fa0/4. Umtshintshi ujonga isiseko sayo kwaye ufumanisa ukuba izibuko Fa0/4 yeye-VLAN10. Emva koku, iswitshi ithegi isakhelo ngenombolo yenethiwekhi, oko kukuthi, incamathela i-VLAN10 header kwipakethi yetrafikhi, kwaye iyithumele ecaleni kwe-trunk kwi-SW1 yesibini yokutshintsha. Olu tshintsho "lufunda" i-header kwaye lubone ukuba ipakethe imiselwe i-VLAN10, ijonge kwi-database yayo ye-VLAN kwaye, ifumanisa ukuba akukho VLAN10 apho, ilahla ipakethi. Ngaloo ndlela, izixhobo PC2,3, 4 kunye 0 unako ukunxibelelana omnye komnye ngaphandle iingxaki, kodwa umzamo ukuseka unxibelelwano neekhompyutha PC1 kunye PC1 uyasilela kuba switsha SW10 akazi nto malunga womnatha VLANXNUMX.
Sinokuyilungisa ngokulula le ngxaki ngokuya kwizicwangciso ze-SW1, sisenza iVLAN10 sisebenzisa i-vlan 10 yomyalelo kwaye singenise igama layo UKUTHENGISA. Makhe sizame ukuphinda i-ping - ubona ukuba iipakethi ezintathu zokuqala zilahlwa, kwaye yesine iphumelele. Oku kuchazwa yinyaniso yokuba ukutshintshwa kuqala kuhlolisise iidilesi ze-IP kwaye kunqunywe idilesi ye-MAC, oku kwathatha ixesha elithile, ngoko ke iipakethi ezintathu zokuqala zalahlwa yi-timeout. Ngoku uxhulumaniso lusekiwe ngenxa yokuba umtshintshi uhlaziye itafile yedilesi ye-MAC kwaye ithumela iipakethi ngqo kwidilesi efunekayo.
Konke endikwenzileyo ukulungisa ingxaki kukungena kwizicwangciso zokutshintsha okuphakathi kwaye ndenze inethiwekhi yeVLAN10 apho. Ngaloo ndlela, nokuba inethiwekhi ayihambelani ngokuthe ngqo kunye nokutshintsha, kusafuneka ukwazi malunga nawo onke amanethiwekhi abandakanyekayo kunxibelelwano lwenethiwekhi. Nangona kunjalo, ukuba inethiwekhi yakho ineetshintshi ezilikhulu, awuyi kuba nakho ngokwasemzimbeni ukuya kusethingi nganye kwaye uqwalasele ngesandla ii-ID zeVLAN. Yiyo loo nto sisebenzisa i-protocol ye-VTP, ulungelelwaniso esiza kujonga kulo kwisifundo sevidiyo esilandelayo.
Ke, namhlanje sigubungele yonke into ebesiyicwangcisile: indlela yokudala iiVLAN, indlela yokwabela amazibuko eVLAN, kunye nendlela yokujonga isiseko sedatha yeVLAN. Ukudala amanethiwekhi, sifaka imodi yokucwangcisa inguqu yehlabathi jikelele kwaye sisebenzise umyalelo we-vlan <number>, sinokuphinda sinikeze igama kwinethiwekhi eyenziwe ngokusebenzisa igama <igama> umyalelo.
Singenza kwakhona iVLAN enye indlela ngokufaka imowudi ye-interface kunye nokusebenzisa i-switchport ukufikelela vlan <inombolo> umyalelo. Ukuba akukho nethiwekhi ngale nombolo, iya kwenziwa ngokuzenzekelayo yinkqubo. Khumbula ukusebenzisa umyalelo wokuphuma emva kokwenza utshintsho kwizicwangciso zokuqala, kungenjalo abayi kugcinwa kwi-database ye-VLAN. Uyakwazi ukwabela izibuko kwiiVLAN ezithile usebenzisa imiyalelo efanelekileyo.
Umyalelo wokufikelela kwimowudi yokutshintsha utshintsha ujongano kwimowudi yofikelelo olumileyo, emva koko inani leVLAN ehambelanayo yabelwe izibuko kunye nokufikelela kwi-switchport vlan <number> umyalelo. Ukujonga i-database ye-VLAN, sebenzisa i-show vlan command, ekufuneka ifakwe kwimodi ye-EXEC yomsebenzisi. Ukujonga uluhlu lwamazibuko esiqu, sebenzisa i show int trunk command.
Enkosi ngokuhlala nathi. Ngaba uyawathanda amanqaku ethu? Ngaba ufuna ukubona umxholo onomdla ngakumbi?
